Description: NOVEL PESTICIDAL COMPOSITION AND BACILLUS THURINGIENSIS STRAIN FIELD OF THE INVENTION The invention is related to a novel strain(s) of Bacillus thuringiensis in which essentially all of the pesticidal activity of said strain is in the supernatant of a fermentation of said strain. The strain produces a substance which has activity against an insect pest(s) of the order Coleoptera and which enhances the pesticidal activity of a Bacillus related pesticide. The invention further relates to pesticidal compositions comprising the substance and a pesticidal carrier, or the substance and a. Bacillus related pesticide, a chemical pesticide and/or a virus with pesticidal properties as well as methods of using the pesticidal compositions to control a pest. BACKGROUND OF THE INVENTION Every year, significant portions of the world's commercially important agricultural crops, including foods, textiles, and various domestic plants are lost to pest infestation, resulting in losses in the millions of dollars. Various strategies have been used in attempting to control such pests. One strategy is the use of broad spectrum pesticides, i.e., chemical pesticides with a broad range of activity. However, there are a number of disadvantages to using such chemical pesticides. Specifically, because of their broad spectrum of activity, these pesticides may destroy non-target organisms such as beneficial insects and parasites of destructive pests. Additionally, these chemical pesticides are frequently toxic to animals and humans, and targeted pests frequently develop resistance when repeatedly exposed to such substances. Another strategy has involved the use of biopesticides, which make use of naturally occurring pathogens to control insect, fungal and weed infestations of crops. Biopesticides comprise a bacterium which produces a toxin, a substance toxic to the pest Biopesticides are generally less harmful to non-target organisms and the environment as a whole than chemical pesticides. The most widely used biopesticide is Bacillus thuringiensis (B.tL). B.t. is a widely distributed, rod shaped, aerobic and spore-forming microorganism. During its sporulation cycle, B.t. produces a protein(s) known as a crystal delta-endotoxin(s), which kills insect larvae. B.t., therefore, is very useful as an agricultural pesticide. Some strains, e.g., Bacillus thuringiensis subsp. kurstaki and Bacillus thuringiensis subsp. aizawai, have been found to be specific for Lepidoptera. Bacillus thuringiensis subsp. israelensis has been found to be specific for Diptera (Goldberg, U.S. Patent No. 4,166,112). Other strains, e.g., Bacillus thuringiensis subsp. tenebrionis (Krieg et al., 1988, U.S. Patent No. 4,766,203), have been found to be specific for Coleoptera. The isolation of another coleopteran toxic Bacillus thuringiensis strain was reported in 1986 (Hernnstadt et al. Bio/Technology vol. 4, 305-308, 1986, US patent 4,764,372, 1988). This strain, designated "Bacillus thuringiensis subsp. san diego", M-7, has been deposited at the Northern Regional Research Laboratory, USA under accession number NRRL B-15939. However, the assignee of the '372 patent, Mycogen, Corp. has publicly acknowledged that Bacillus thuringiensis subsp. san diego is Bacillus thuringiensis subsp. tenebrionis. Furthermore, the '372 patent has been assigned to Novo Nordisk A/S. Additionally, there has been disclosed a B.t. strain which is toxic against Lepidoptera and Coleoptera (PCT Application No. WO 90/13651). The toxin disclosed in PCT Application No. WO 90/13651 has a molecular weight of 81 kd. During its sporulation cycle, B.t. produces a protein(s) in crystal form known as a crystal delta-endotoxin(s), having a molecular weight ranging from 27-140 kd, which upon ingestion kills insect larvae. Toxic activity may reside in one or more of such delta- endotoxins in a given B.t. strain. Most delta-endotoxins are protoxins that are proteolytically converted into smaller toxic (truncated) polypeptides in the target insect midgut (Hδfte and Whiteley, 1989, Microbiol. Rev. 53:242-255). The delta-endotoxins are encoded by c - crystal protein) genes. The cry genes have been divided into six classes and several subclasses based on structural similarities and pesticidal specificity. The major classes are Lepidoptera-specific (cry→T); Lepidoptera-and Diptera-specific crylf); Coleoptera-specific (crylll); Diptera-specific (crylV) (Hδfte and Whiteley, 1989, Microbiol. Rev. 53:242-255); Coleoptera- and Lepidoptera-specific (referred to as cryV genes by Tailor et al., 1992, Molecular Microbiology 6:1211-1217); and Nematode-specific (referred to as cryV and cryVI by Feitelson et al., 1992, Bio/Technology 10:271-275) genes. Delta-endotoxins have been produced by recombinant DNA methods. The delta-endotoxins produced by recombinant DNA methods may or may not be in crystal form. B.t. delta-endotoxin is water insoluble except at alkaline pH, and is almost always plasmid encoded. Some strains of Bacillus thuringiensis have been shown to produce a heat-stable pesticidal adenine-nucleotide analog, known as β-exotoxin or thuringiensin, which is pesticidal alone (Sebesta et al., in H.D. Burges (ed.), Microbiol Control of Pests and Plant Diseases, Academic Press, New York p. 249-281, 1981). β-exotoxin has been found in the supernatant of some Bacillus thuringiensis cultures. It has a molecular weight of 789 and is comprised of adenosine, glucose, and allaric acid (Lϋthy et al., in Kurstak (ed.), Microbial and Viral Pesticides, Marcel Dekker, New York, 1982, pp. 35-72). Its host range includes, but is not limited to, Musca domestica, Mamestra coηfigurata Walker, Tetranychus urticae, Drosophila melanogaster, and Tetranychus cinnabarinus. The toxicity of β-exotoxin is thought to be due to inhibition of DNA-directed RNA polymerase by competition with ATP. It has been shown that β-exotoxin is encoded by a Cry plasmid in five Bacillus thuringiensis (B.t.) strains and that β-exotoxin may be classified as type I or type II β-exotoxin (Levinson et al., 1990, /. Bacteriol. 172:3172-3179). β-exotoxin type I was found to be produced by B.t. subsp. thuringiensis serotype 1, B.t. subsp. tolworthi serotype 9, and -B.t. subsp. darmstadie sis serotype 10. β-exotoxin type II was found to be produced by B.t. subsp. morrisoni serotype 8ab and is active against Leptinotarsa decemlineata (Colorado potato beetle). Other water soluble substances that have been isolated from B.t. include alpha- exotoxin which is toxic against the larvae of Musca domestica (Luthy, 1980, FEMS Microbiol. Lett. 8:1-7); gamma-exotoxins, which are various proteolytic enzymes including lecithinases, chitinases, and proteases, the toxic effects of which are expressed only in combination with beta-exotoxin or delta-endotoxin (Forsberg et al., 1976, Bacillus thuringiensis: Its Effects on Environmental Quality, National Research Council of Canada, NRC Associate Committee on Scientific Criteria for Environmental Quality, Subcommittees on Pesticides and Related Compounds and Biological Phenomena); sigma exotoxin which has a structure sirnilar to beta- exotoxin, and is also active against Leptinotarsa decemlineata (Argauer et al., 1991, /. Entomol. Sci. 26:206-213); and anhydrothuringiensin (Coll. Czechoslovak Chem. Comm. 40, 1775, 1975). WO 94/09630 discloses a water soluble substance that enhances the activity of Bacillus thuringiensis var. kurstaki and Bacillus thuringiensis var. aizawai. Stonard et al. (1994, In Natural and Engineered Pest Management Agents, Paul A. Mann, Robert M. Hollingworth, eds., ACS, Washington, D.C., pp. 25-36) discloses diabroticins having the structure 1 R, Ri, R 2 =H, R 3 =OH Diabroticin A 2 R, R l5 R 2 , R 3 =H Diabroticin B Diabroticins were isolated from-B. subtilis and have activity against Diabrotica undecimpunctata, Leptinotarsa decemlineata, Anthomus grandis Boheman, mosquito larvae, Staphylococcus aureus, and Micrococcus lutea, but did not have activity against European corn borer, Escherichia coli, B. subtilis, and Pseudomonas aeruginosa. Activity against other pests were not disclosed in Stonard et al. Diabroticin A was also isolated from fermentation broths of B. cereus. The art has strived to achieve increased mortality of -B.t. formulations. Means have included searching for new strains with increased mortality, engineering present strains, and designing more effective formulations by combining B.t. spores and/or crystals with new pesticidal carriers or with chemical pesticides. It is an object of the present invention to improve the insecticidal activity of known B.t. formulations. It is also an object of the present invention to enhance the pesticidal activity of pesticides as well as find novel uses for known pesticidal products. It is advantageous to isolate new strains oi Bacillus thuringiensis to produce new substances so that there exists a wider spectrum of biopesticides for any given insect pest SUMMARY OF THE INVENTION The invention is related to a novel Bacillus thuringiensis strain in which essentially all of the pesticidal activity of said strain is in the supernatant of a fermentation of said strain. Crystal protein and spores obtained from a fermentation of a Bacillus thuringiensis strain of the present invention do not possess any pesticidal activity. In a specific embodiment, the strain is selected from the group consisting of EMCC-0077 having the identifying characteristics of NRRL B-21090, or mutants thereof having substantially the same properties of EMCC-0077, EMCC-0078 having the identifying characteristics of NRRL B-21091, or mutants thereof having substantially the same properties of EMCC-0078, EMCC-0079 having the identifying characteristics of NRRL B-21092, or mutants thereof having substantially the same properties of EMCC-0079, EMCC-0080 having the identifying characteristics of NRRL B-21093, or mutants thereof having substantially the same properties of EMCC-0080, and EMCC-0081 having the identifying characteristics of NRRL B-21094, or mutants thereof having substantially the same properties of EMCC-0081. A substance which has pesticidal activity against an insect pest of the order Coleoptera and acts together as, for example, a potentiator or synergizer with a different Bacillus related pesticide against a pest is obtained from a supernatant of a fermentation of said strain. In a preferred embodiment, said substance, has an LC 5 0 (LCsois the concentration of a given pesticidal substance required to -rill 50% of the pests) of 126 μg of active ingredient g of total material against Leptinotarsa texana. The LC 5 0 of the pellet of the fermentation of said strain is more than about 3000 μg of active ingredient/g of total material as assayed by bioassay. In another embodiment, said substance has pesticidal activity against an insect pest of the order Coleoptera. In a most specific embodiment, said substance has pesticidal activity against an insect pest of the species Diabrotica undecimpunctata, Leptinotarsa texana, Anthomus grandia, as well as surprisingly activity against an insect pest of the species Ips calligraphus, Popilliajaponicus, Epilachna varivastis, Leptinotarsa decemlineata, and Dendroctonusfrontalis of the order Coleoptera. In a specific embodiment, said substance enhances the insecticidal activity of Bacillus thuringiensis crystal delta-endotoxin(s) against an insect pest(s). In a specific embodiment, said substance enhances the insecticidal activity of Bacillus thuringiensis subsp. tenebrionis crystal delta-endotoxin against an insect pest(s) of the order Coleoptera. As defined herein, "a Bacillus related pesticide" is a Bacillus (e.g., Bacillus thuringiensis ox Bacillus subtilis) strain or spore. A Bacillus related pesticide may also be a substance derived from Bacillus, e.g., protein or fragment thereof having activity against or which kill pests; a substance that provides plant protection, e.g., antifeeding substance; or a microorganism capable of expressing a Bacillus gene encoding a Bacillus protein or fragment thereof having activity against or which kill pests (e.g., Bacillus thuringiensis delta-endotoxin) and an acceptable carrier (see next section on Compositions). The pest may be, for example, an insect, a nematode, a mite, or a snail. A microorganism capable of expressing a Bacillus gene encoding a Bacillus protein or fragment thereof having activity against or which kill pests inhabiting the phylloplane (the surface of the plant leaves), and/or the rhizosphere (the soil surrounding plant roots), and/or aquatic environments, and is capable of successfully competing in the particular environment (crop and other insect habitats) with the wild-type microorganisms and provide for the stable maintenance and expression of a Bacillus gene encoding a Bacillus protein or fragment thereof having activity against or which kill pests. Examples of such microorganisms include but are not limited to bacteria, e.g., genera Bacillus, Pseudomonas, Erwinia, Serratia, Klebsiella, Xanthomonas, Streptomyces, Rhizobium, Rhodopseudomonas, Methylophilius, Agrobacterium, Acetobacter, Lactobacillus, Arthrobacter, Azotobacter, Leuconostoc, Alcaligenes, and Clostridium; algae, e.g., families Cyanophyceae, Prochlorophyceae, Rhodophyceae, Dinophyceae, Chrysophyceae, Prymnesiophyceae, Xanthophyceae, Raphidophyceae, Bacillariophyceae, Eustigmatophyceae, Cryptophyceae, Euglenophyceae, Prasinophyceae, and Chlorophyceae; and fungi, particularly yeast, e.g., genera Saccharomyces, Cryptococcus, Kluyveromyces, Sporobolomyces, Rhodotorula, and Aureobasidium. As defined herein, "pesticidal activity" measures the amount of activity against a pest through killing or stunting of the growth of the pest or protecting the plant from pest infestation. The invention further relates to pesticidal compositions comprising the substance and a Bacillus related pesticide as well as methods of using the pesticidal compositions to control a pest. The invention is further directed to a method for obtaining "substantially pure" substance of the present invention comprising the steps of (a) culturing a Bacillus thuringiensis strain on a suitable growth medium; (b) recovering the supernatant of (a); and (c) subjecting the supernatant of step (b) to column chromatography to purify the substance. As defined herein a "substantially pure" substance means a substance which contains less than 5% of contaminants, for example, delta-endotoxin protein.

It is to be understood that the invention extends to each of the stereoisomeric forms of the compounds of structure I as well as racemates. In most specific embodiments, the substance has the structure la, hereafter referred to as "la" or lb, hereafter referred to as "lb". la: R, RL R 2 , R 3 =H lb: R, Ri, R 2 =H, R 3 =OH Bacillus thuringiensis may be cultured using media and fermentation techniques known in the art (see, for example, Rogoff et al., 1969, J. Invertebrate Path. 14:122-129; Dulmage et al., 1971, J. Invertebrate Path. 18:353-358; Dulmage et al., in Microbial Control of Pests and Plant Diseases, H.D. Bulges, ed., Academic Press, N.Y., 1980). Upon completion of the fermentation cycle, the supernatant can be recovered by separating B.t. spores and crystals from the fermentation broth by means well known in the art, e.g., centrifugation and/or ultrafiltration. Said substance is contained in the supernatant which may be recovered by means well known in the art, e.g., ultraf-ltration, evaporation, and spray-drying. Alternatively, the substance(s) of the present invention may be obtained by chemical synthesis using procedures known in the art. To obtain structure I, the simple pyrazine ring with appropriate substitution and protecting groups can be formed by a number of reactions, for example, spontaneous condensation of alpha-aminocarbonyl compounds. A dihydropyrazine intermediate is formed but is readily oxidized with oxygen to the pyrazine. Dimerization of a single alpha- aminocarbonyl compound by this method would lead to a single pyrazine, whereas a reaction with two different alpha-aminocarbonyl compounds would lead to three products; said substance would be isolated by chromatographic separation (see Figure 1). The latter reaction allows synthesis of pyrazines with different substituents off each side of the ring. Purification of the substance(s) can be carried out by various procedures known in the art, including but not limited to chromatography (e.g., ion exchange, affinity, and size exclusion column chromatography), electrophoretic procedures, differential solubility, extraction, or any other standard technique known in the art (see, for example, Protein Purification, eds. J-C. Janson and Lars Ryden, VCH Publishers, New York, 1989). The activity of said substance may be bioassayed using procedures known in the art, such as artificial diet incorporation, artificial diet overlay, leaf painting, leaf dip, and foliar spray. Specific examples of such bioassays are given in the Examples section, infra. Compositions Comprising the Substance Said substance can be formulated alone; along with a Bacillus related pesticide which as defined supra is a Bacillus strain, spore, protein or fragment thereof having activity against or which kills pests and optionally an acceptable carrier into an pesticidal composition(s) that is for example, a suspension, a solution, an emulsion, a dusting powder, a dispersible granule, a wettable powder, an emulsiflable concentrate, an aerosol or impregnated granule. Examples of such Bacillus strains include but are not limited to Bacillus thuringiensis subsp. kurstaki (marketed as DIPEL™ from Abbott Laboratories, Inc., JAVELIN™ from Sandoz, BIOBIT™ from Novo Nordisk A/S, FORAY™ from Novo Nordisk A/S, MVP™ from Mycogen, BACTOSPEINE™ from Novo Nordisk A/S, and THURICIDE™ from Sandoz); Bacillus thuringiensis subsp. aizawai (marketed as FLORBAC™ from Novo Nordisk A/S, and XENTAR1™ from Abbott Laboratories, Inc.); Bacillus thuringiensis subsp. tenebrionis (marketed as NOVODOR™ from Novo Nordisk A/S, TRIDENT™ from Sandoz, M-TRAK™ and M-ONE™ from Mycogen); Bacillus thuringiensis subsp. israelensis (marketed either as BACTIMOS™ or SKEETAL™ from Novo Nordisk A/S, TEKNAR™ from Sandoz, and VECTOBAC™ from Abbott Laboratories, Inc.); Bacillus sphaericus (marketed as SPHERIMOS™ from Novo Nordisk A/S); Bacillus thuringiensis kurstakiltenebrionis (marketed as FOIL™ from Ecogen); Bacillus thuringiensis kurstakil aizawai (marketed as CONDOR™ from Ecogen and AGREE™ from Ciba-Geigy); and Bacillus thuringiensis kurstaki/kurstaki (marketed as CUTLASS™ from Ecogen). The Bacillus related protein may be selected from the group including but not limited to Cryl, Cryπ, Cryiπ, CrylV, CryV, and CryVI. Said substance may also be formulated with other factors or substances obtained from the supernatant of a Bacillus supernatant including but not limited to an exotoxin and/or the enhancing factor disclosed in application serial no. 08/095,240, filed July 20, 1993, incorporated herein by reference. Optionally, the formulation may also comprise a Bacillus related pesticide, chemical pesticide and/or a virus with pesticidal properties and an acceptable carrier. In a specific embodiment, the components of said composition may act in a synergistic fashion. As a result, said composition may have greater efficacy than can be attained with each individual component. Synergism may also be manifested by equal or greater efficacy with lower and/or less frequent doses than would be required for each individual component Alternatively, said substance may act to enhance a Bacillus related pesticide. In compositions comprising the substance and a Bacillus related pesticide, the substance is present in the amount of about 0.001 to about 300 g per LTU. As defined herein, "LTU" is a Leptinotarsa texana unit as determined by bioassay. The bioassay compares the sample to a standard Bacillus reference material using Leptinotarsa texana or other pest as the standard test organism. The potency is determined by dividing the reference standard LC 50 then multiplying by the reference standard potency. In another embodiment, the composition may comprise said substance in substantially pure form or a supernatant from Bacillus in dry, concentrated, or liquid form and a suitable pesticidal carrier, examples of which are disclosed infra. This composition may be applied separately to a plant, e.g., transgenic plants. Specifically, the composition may be applied to a plant previously containing a Bacillus thuringiensis gene. In another embodiment the composition may be applied to a plant previously exposed to a Bacillus thuringiensis composition. The substance is present in the composition at a concentration of from about 0.001% to about 60% (w/w). Such compositions disclosed above may be obtained by the addition of a surface active agent an inert carrier, a preservative, a humectant a feeding stimulant an attractant an encapsulating agent, a binder, an emulsifier, a dye, a U. V. protectant, a buffer, a flow agent or other component to facilitate product handling and application for particular target pests. Suitable surface-active agents include but are not limited to anionic compounds such as a carboxylate, for example, a metal carboxylate of a long chain fatty acid; an N- acylsarcosinate; mono or di-esters of phosphoric acid with fatty alcohol ethoxylates or salts of such esters; fatty alcohol sulphates such as sodium dodecyl sulphate, sodium octadecyl sulphate or sodium cetyl sulphate; ethoxylated fatty alcohol sulphates; ethoxylated alkylphenol sulphates; lignin sulphonates; petroleum sulphonates; alkyl aryl sulphonates such as alkyl- benzene sulphonates or lower alkylnaphthalene sulphonates, e.g., butyl-naphthalene sulphonate; salts or sulphonated naphthalene-formaldehyde condensates; salts of sulphonated phenol-formaldehyde condensates; or more complex sulphonates such as the amide sulphonates, e.g., the sulphonated condensation product of oleic acid and N-methyl taurine or the dialkyl sulphosuccinates, e.g., the sodium sulphonate or dioctyl succinate. Non-ionic agents include but are not limited to condensation products of fatty acid esters, fatty alcohols, fatty acid amides or fatty-alkyl- or alkenyl-substituted phenols with ethylene oxide, fatty esters of polyhydric alcohol ethers, e.g., sorbitan fatty acid esters, condensation products of such esters with ethylene oxide, e.g., polyoxyethylene sorbitol fatty acid esters, block copolymers of ethylene oxide and propylene oxide, acetylenic glycols such as 2,4,7,9-tetraethyl-5-decyn- 4,7-diol, or ethoxylated acetylenic glycols. Examples of a cationic surface-active agent include, for instance, an aliphatic mono-, di-, or polyamine as an acetate, naphthenate or oleate; an oxygen-cont ning amine such as an amine oxide of polyoxyethylene alkylamine; an amide- linked amine prepared by the condensation of a carboxylic acid with a di- or polyamine; or a quaternary ammonium salt Examples of inert materials include but are not limited to inorganic minerals such as kaolin, mica, gypsum, fertilizer, phyllosilicates, carbonates, sulfates, or phosphates; organic materials such as sugar, starches, or cyclodextrins; or botanical materials such as wood products, cork, powdered corncobs, rice hulls, peanut hulls, and walnut shells. The compositions of the present invention can be in a suitable form for direct application or as a concentrate or primary composition which requires dilution with a suitable quantity of water or other diluent before application. The pesticidal concentration will vary depending upon the nature of the particular formulation, specifically, whether it is a concentrate or to be used directly. The composition contains 1 to 98% by weight of a solid or hquid inert carrier, and 0 to 50%, preferably 0.1 to 50% of a surfactant. These compositions will be administered at the labeled rate for the commercial product preferably about 0.01 pound to 5.0 pounds per acre when in dry form and at about 0.01 pint to 25 pints per acre when in hquid form. In a further embodiment the Bacillus related pesticide and/or substance can be treated prior to formulation to prolong the pesticidal activity when applied to the environment of a target pest as long as the pretreatment is not deleterious to the Bacillus related pesticide or substance. Such treatment can be by chemical and/or physical means as long as the treatment does not deleteriously affect the properties of the composition(s). Examples of chemical reagents include but are not limited to halogenating agents; aldehydes such as formaldehyde and glutaraldehyde; anti-infectives, such as zephiran chloride; alcohols, such as isopropranol and ethanol; and histological fixatives, such as Bouin's fixative and Helly's fixative (see, for example, Humason, Animal Tissue Techniques, W.H. Freeman and Co., 1967). The compositions of the invention can be applied directly to the plant by, for example, spraying or dusting at the time when the pest has begun to appear on the plant or before the appearance of pests as a protective measure. Plants to be protected within the scope of the present invention include but are not limited to cereals (wheat barley, rye, oats, rice, sorghum and related crops), beets (sugar beet and fodder beet), drupes, pomes and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries, and blackberries), leguminous plants (alfalfa, beans, lentils, peas, soybeans), oil plants (rape, mustard, poppy, olives, sunflowers, coconuts, castor oil plants, cocoa beans, groundnuts), cucumber plants (cucumber, marrows, melons), fibre plants (cotton, flax, hemp, jute), citrus fruit (oranges, lemons, grapefruit, mandarins), vegetables (spinach, lettuce, asparagus, cabbages and other brassicae, carrots, onions, tomatoes, potatoes), lauraceae (avocados, cinnamon, camphor), deciduous trees and conifers (e.g., linden-trees, yew-trees, oak-trees, alders, poplars, birch-trees, firs, larches, pines), or plants such as maize, turf plants, tobacco, nuts, coffee, sugar cane, tea, vines, hops, bananas and natural rubber plants, as well as ornamentals. The substance may be applied by foliar, furrow, broadcast granule, "lay-by", or soil drench application. It is generally important to obtain good control of pests in the early stages of plant growth as this is the time when the plant can be most severely damaged. The spray or dust can conveniently contain another pesticide if this is thought necessary.

The following examples are presented by way of illustration, not by way of limitation. EXAMPLES EXAMPLE 1: Cultivation of Variou -B.t. Isolates Subcultures of EMCC-0077, EMCC-0078, EMCC-0079, EMCC-0080, and EMCC-0081, maintained on a Nutrient Broth Agar slants, are used to inoculate 250 ml baffled shake flasks containing 50 ml of medium with the following composition. Com Steep liquor 15 g L Maltrin-100 40 g L Potato Starch 30 g L KH 2 PO 4 1.77 g/L K 2 HPO 4 4.53 g/L The pH of the medium is adjusted to 7.0 using 10 N NaOH. After inoculation, shake flasks are incubated at 30°C on a rotary shaker at 250 rpm for 72 hours. The whole culture broths are used for testing against Diabrotica undecimpunctata. EXAMPLE 2: Diabrotica undecimpunctata Activity In Whole Culture Broth From Various B.t. Isolates 2.5 ml of the whole culture broths obtained from the above fermentation are removed and transferred from the shake flasks into 50 ml polypropylene bioassay tubes. Diabrotica undecimpunctata diet is added into each tube to a final volume of 25 ml. The diet and the testing material is then mixed vigorously and dispensed into bioassay trays for bioassay. Three to six eggs oi Diabrotica undecimpunctata are applied on the surface of the "diet". Mylar is ironed onto the bioassay trays and the trays are incubated at 28°C without photoperiod. Scoring is carried out at 7 days. Mortality is scored on the 7th day after incubation. SS7 = the size of dead larvae on the 7th day when compared with the live, control larvae on the same day as SS7 of 4. SS7 = 3, SS7 = 2, and SS7 = 1 represent the size of the larvae as 75%, 50%, & 25% respectively of the live, control larvae of 4. The results are shown below in TABLE 1. These results indicate that in all 5 strains tested there was 100% mortality. Furthermore, the dead larvae were 12.5% of the size of the live control larvae. TABLE 1 Diabrotica undecimpunctata Activity in Whole Culture Broths Strain % Mortality SS7 EMCC-0077 100 0.5 EMCC-0078 100 0.5 EMCC-0079 100 0.5 EMCC-0080 100 0.5 EMCC-0081 100 0.5 EXAMPLE 3: Localization oi Diabrotica undecimpunctata Activity In order to test whether the Diabrotica undecimpunctata activity is associated with the delta-endotoxin/spores or the supernatant, 2.5 ml of the whole culture broths from EMCC-0077, EMCC-0080, EMCC-0081, and NB125 (aBacillus thurigiensis subsp. tenebrionis grown under the identical conditions) is centrifuged in a Sorvall RC-5B centrifuge at 15,000 rpm (Sorvall SS34 rotor) for 15 minutes to separate the supernatant and the pellet. The crystal delta-endotoxins plus the spores are recovered in the pellet The delta-endotoxins produced by the Diabrotica undecimpunctata-acύve B.t. isolate EMCC-0077 have molecular weights of 66kD, 29kD and 12kD as determined by SDS-PAGE. The delta-endotoxins produced by the Diabrotica undecimpunctata-acύve B.t. isolate EMCC-0078 have molecular weights of 153kD, 77kD, 67kD, 61kD, 50kD, 42kD, 34kD, 30kD, 24kD as determined by SDS-PAGE. The delta-endotoxins produced by the Diabrotica undecimpunctata-acύve B.t. isolate EMCC-0079 have a molecular weight of 135-145kD, as determined by SDS-PAGE. The delta-endotoxins produced by the Diabrotica undecimpunctata-acύve B.t. isolate EMCC- 0080 have molecular weights of 94kD and 40kD, as determined by SDS-PAGE. The delta- endotoxins produced by the Diabrotica undecimpunctata-acύve B.t. isolate EMCC-0081 have molecular weights of 129kD and 32kD as determined by SDS-PAGE. Each supernatant (2.5 ml) obtained from the above centrifugation is transferred into a 50 ml polypropylene bioassay tube. The pellet is then resuspended into 2.5 ml of sterile distilled water and transferred into a separate 50 ml polypropylene bioassay tube. Diabrotica undecimpunctata diet is then added into bioassay tubes which contained either the supernatant or the resuspended pellet to a final volume of 25 ml. The remaining steps of bioassay are identical to those described above. The scoring is also the same as described above. The results as seen in TABLE 2 show that the Diabrotica undecimpunctata activity from EMCC-0077, EMCC-0080, and EMCC-0081 is present in all of the supernatants, whereas the minor Diabrotica undecimpunctata activity from the known Bacillus thuringiensis subsp. tenebrionis is concentrated in the pellet (spore plus crystal).

The filtered supematant is applied to eggplant foliage at a volume of 20 GPA (gallons per acre). Dilutions are 0, 1:1, 1:4, 1:8 (supernatantideionized water, v/v). Leptinotarsa texana larvae are exposed to the treated foliage following standard protocol. Each plant is loaded with 20 larvae oi Leptinotarsa texana. The results as tabulated in TABLE 3 below show that the filtered supematant of EMCC-0080 is active against Leptinotarsa texana.

However, when the eggplant foliage is treated with 1.25% or 2.5% of 10X concentrated EMCC-0080 supematant plus 200 μg of NOVODOR™ (Novo Nordisk A/S, Bagsvaerd, Denmark) per ml, a synergistic effect is obtained as evidenced by the sharp decline of the LC 50 and LC 90 of NOVODOR™. The data is presented in TABLE 4 below.

EXAMPLE 6: Purification of Coleopteran-Active Substance Produced By B.t. Strain EMCC- QQM B.t. strain EMCC-0080 is grown for 24 hours at 30°C in a medium with the following composition in grams per liter at pH 7.0: Maltodextrin 40 g Soy Protein 40 g KH 2 PO 4 1.8 g K 2 HPO 4 4.5 g MgSO 4 -7H 2 O 0.3 g Trace metals 0.2 ml Cells and other insolubles are removed from the whole culture broth of -B.t. strain EMCC-0080 by centrifugation followed by filtration of the resulting supematant through Celite and a 0.2 μ membrane. The resulting permeate is then concentrated 10-fold by evaporation. The purification of the coleopteran-active substance(s) from the 10X concentrated permeate is achieved using a four step purification procedure. During purification, activity is monitored by a Diabrotica undecimpunctata surface bioassay as described infra, and purity is determined by capillary electrophoresis as described in EXAMPLE 8. All chromatographic steps employ detection at 226 nm. Specifically, the surface bioassay is conducted as follows. Samples of the 10X concentrated permeate are applied to individual wells of a microtiter plate containing 200 μl of solidified artificial insect diet per well, and then air dried. Two to four neonates oi Diabrotica undecimpunctata (com rootworm, CRW) are gently placed in each well with a paintbrush. The microtiter plates are then sealed with Mylar punched with holes for air exchange and are incubated at 30°C and 80% humidity. Scoring for percent mortality is carried out at 5 days. In the first step, the 10X concentrated permeate is first purified by Pharmacia SP Sephadex® C-25 (cation exchange) column chromatography (5 x 30 cm). A 450 ml sample of the 10X concentrated permeate is diluted to 18 liter with deionized water, loaded onto the column which is pre-equilibrated with 20 mM ammonium acetate buffer at pH 5.0. The column is eluted at 18 ml per minute with a 5.0 liter continuous gradient from 20 mM to 0.5M ammonium acetate buffer at pH 5.0. Fractions of 10 ml are collected, bioassayed, and examined for purity. The active fractions are pooled (approximately 150 ml), lyophilized, and redissolved in deionized water to approximately 1/5 the original volume. In the second step, a 25 ml sample from the first step is loaded onto a BioRad P2 (extra fine) size exclusion column (5 X 100 cm) which is pre-equilibrated with deionized water. The column is eluted at a flow rate of 1 ml per minute with deionized water. Fractions of 10 ml are collected, bioassayed, and examined for purity by capillary electrophoresis. The active fractions are pooled (approximately 400 ml). In the third step, the 400 ml pool from the second step is diluted to 16 liters with deionized water. The solution is loaded onto a Pharmacia S Sepharose® Fast Flow (strong cation exchange) column (5 X 30 cm) which is pre-equilibrated with 20 mM ammonium acetate buffer at pH 5.0. The column is eluted at a flow rate of 17 ml per minute with a 5.0 liter continuous gradient from 20 mM to 0.5 M ammonium acetate buffer at pH 5.0. Fractions of 20 ml are collected, bioassayed, and examined for purity. The active fractions are pooled (approximately 250 ml) and then lyophilized to dryness to remove the volatile ammonium acetate buffer. In the fourth step, the lyophilized pool from third step is dissolved in 400 ml deionized water. The solution is loaded onto a BioRad Chelex® 100 column (0.9 X 30 cm) which was pre-equilibrated with 20 mM ammonium formate buffer at pH 4.0. The column is eluted at a flow rate of 5 ml per minute with a 2.4 liter step gradient from 0.02 — * > 0.1 → 0.2 -" 0.35 -→ 0.5 → 1.0 M ammonium formate buffer at pH 4.0. Fractions of 20 ml are collected, bioassayed, and examined for purity. The active fractions are pooled (approximately 300 ml) and then lyophilized to dryness to remove the volatile ammonium formate buffer. Capillary electrophoresis shows the purified coleopteran-active material comprises two compounds, la and lb. EXAMPLE 7: Structure Elucidation of Coleopteran-Active Substances The structures of compounds la and lb are elucidated from the spectroscopic data collected on their acetylated derivatives. A 114 mg mixture of la and lb is acetylated in 5.0 ml pyridine with 5.0 ml acetic anhydride and a crystal of 4-di-methylaminopyridine as a catalyst for 24 hours at room temperature, and then purified by semi-preparative RP-Cis HPLC. A 5 mg sample in 25 μl is loaded onto the column and eluted at 4 ml per minute with 80% water-20% acetonitrile. Detection is at 254 nra Two acetylated derivatives are obtained from the purification, designated as Derivative A and Derivative B. The structures of Derivatives A and B are shown in Figure 4. NMR spectroscopic data collected on Derivative A indicates the presence of 14 carbons and 17 protons. However, mass spectral data suggests a molecular weight of 652 and a formula of C 2 sH 4 oN 6 θι 2 (exact mass, 653.2801, MH+, calc. 653.2782). Therefore, the compound is determined to be symmetrical where only half of the signals are observed by NMR. Several spin systems are observed by NMR. A central pyrazine ring substituted in the 2 and 5 positions is indicated by the high field proton singlets at 8.6 ppm (H-3 and H-6) which shows long range couplings to all of the carbons in the ring and to the first carbon of the side chain (C-7). The side chain of three carbons is acetylated at both position 7 and 8 with a methylene at position 9. Carbon 9 is found to have a long range correlation to the carbonyl of an ester, and the ester is determined to be part of an alanine which is acetylated at the amino group. The structure of Derivative B differs in one position from Derivative A. In one of the side chains of Derivative B, the C-7 carbon no longer is acetylated or attached to oxygen, but is found to be a methylene. The other side chain is identical to that in Derivative A. This difference of only one oxygen is also observed in the mass spectral data. Mass spectral data is obtained with an exact mass of 595.2722 (MH+, calc. 595.2727) for Derivative B, indicating a formula of C 26 H 38 N 6 O 1 0. The optical densities of Derivatives A and B are as follows: Derivative A [α] D 27 = -6.9°C and Derivative B [α] D 27 = +32°C. Full assignments of the *H and 13 C NMR data are made on the basis of decoupling ejφeriments, COSY, HMQC and HMBC. The assignments are presented in TABLE 5.

The structures of la and lb are shown below. la: R, Ri, R 2 , R 3 =H lb: R, R l5 R 2 =H, R 3 =OH The properties of compounds la and lb and their acetylated derivatives are summarized below: Derivative A Molecular weight 652 Empirical formula: C 28 H 40 N 6 O 12 UV(MeOH): 275, 310 nm MS (FAB): (M+H) m/z 653.2801, calc. 653.2782 Derivative B: Molecular weight 594 Empirical formula: C 2 6H38 N 6θlO UV (MeOH): 275, 310 nm MS (FAB): (M+H) m/z 595.2722, calc. 5952727 la: Molecular weight 400 Empirical formula: deHzgNeOe UV (H 2 0): 275, 310 nm MS (FAB): (M+H) 401 lb: Molecular weight 384 Empirical formula: UN (H 2 0): 275, 310 nm MS (FAB): (M+H) 385 EXAMPLE 8: Ouantitation of Compounds la and lb in Fermentation Broths B.t. strain EMCC-0080 is grown as described in EXAMPLE 1. The concentration of compounds la and lb in the fermentation broth is determined by capillary electrophoresis. Specifically, a BioRad Biofocus 3000 Capillary Electrophoresis System equipped with an uncoated capillary (50 μm x 50 cm), 0. IM phosphate at pH 2.5, voltage at 20 KV, positive to negative polarity, and detection at 200 nm is used for quantification. The sample volume is 30 μl with a 5 psi second injection. The analysis time is 10 minutes with the coleopteran-active compounds la and lb eluting at 6.0 and 5.9 minutes, respectively. Alternatively, a Beckman P/ACE 2100 Capillary Electrophoresis System equipped with an uncoated capillary (50 μm x 47 cm), 0. IM phosphate buffer at pH 2.5, voltage at 20 KV, positive to negative polarity, and detection at 200 nm is used for quantification. The sample volume is 30 μl with a 10 second pressure injection. The analysis time is 10 minutes with the coleopteran-active compounds la and lb eluting at 7.0 and 6.7 minutes, respectively. Cells and other insolubles are removed from the whole culture broth of -B.t. strain EMCC-0080 by centrifugation and by filtration through Celite and a 0.2 membrane. The resulting supernatant is analyzed by capillary electrophoresis as described above. The results indicated that coleopteran-active compounds la and lb are each present at a level of approximately 90 mg per liter culture broth. EXAMPLE 9: Potency Determination of Compounds la and lb The relative potency of a crude mixture of compounds la and lb (approximately 1:1 w/w) is determined using Leptinotarsa texana as the test insect and comparing mortality associated with an internal standard preparation oi Bacillus thuringiensis subsp. tenebrionis. Foliar bioassays are performed to determine the potency of a crude mixture of compounds la and lb against Leptinotarsa texana. To perform the foliar bioassay, test materials and standards are weighed into 50 ml centrifuge tubes and suspended with deionized water containing 0.1% Tween® 20. 1,200 mg oi Bacillus thuringiensis subsp. tenebrionis standard are weighed out and suspended to give a final concentration of 12,000 μg/g. The test samples (i.e., NOVODOR™ and NOVODOR™ with compounds la and lb) are treated in a similar fashion unless a rate finding bioassay has shown that the delivered dosage is too high or too low to result in a sufficient number of valid data points. If this is the case, the concentration of the primary stock solution is increased or decreased by changing the amount of diluent added to the stock solution. Each sample is then homogenized for 30 seconds using a Virtis Homogenizer, and sonicated for 20 seconds at 100 Watts using a Braunsonic 1510 ultrasonic homogenizer. Each of these stock solutions are then diluted using a Hamilton Microlab 1000 to give seven serial dilutions consisting of 3,000, 2,000, 1333, 857, 545, 364, and 245 μg/ml in a total of 16 ml. Each of these 16 ml solutions are applied to approximately 288 square inches of eggplant leaves using a Devries Linear Track sprayer calibrated to deliver 20 gallons per acre. Control leaves are sprayed with 16 ml deionized water. Leaves are air dried and then placed over the rim of a one ounce clear plastic cup containing 5 second instar Leptinotarsa texana larvae. Cardboard lids are then placed over the leaf and the lid is pressed into place, cutting a 4 cm leaf disk and sealing it inside the cup. The cups are then inverted and the larvae dropped onto the leafs treated surface. Eight cups are prepared for each one of the seven serial dilutions. The cups are taped together, labeled, placed on racks, and incubated for 3 days at 30°C and 65% relative humidity. These 56 experimental cups and 8 control cups constitute one bioassay. After three days, insect mortality is rated. Each cup is given a sharp blow and larvae that did not move are counted as dead. Percent mortality is calculated, and the data are analyzed via parallel probit analysis. LC 50 S, LC9 0 S, slope of the regression lines, coefficient of variation, and potencies are estimated. To determine the potency, a crude mixture of compounds la and lb is diluted, bioassayed, and compared to a Bacillus thuringiensis subsp. tenebrionis standard which is assigned a potency of 20,000 LTU/gram (Leptinotarsa texana Units/gram). The potency results are presented in TABLE 6, infra, and indicate that the crude mixture of compounds la and lb (1:1 w/w) has a potency of 75,555 LTU per g active ingredient with an LC 50 of 70 ug per ml (1.8 mg total active ingredient per ml).

Foliar bioassays are performed against Leptinotarsa texana as described in EXAMPLE 9 to determine the level of potentiation gained by adding compounds la and lb to NOVODOR™. A crude mixture of compounds la and lb is added to NOVODOR™. Solutions are serially diluted using the Hamilton Microlab 1000 to give stock solutions containing NOVODOR™ at 1000.0, 666.7, 444.4, 285.7, 181.8, 121.2, and 80.0 μg/g. Two different dilutions of a mixture of la and lb are prepared resulting in seven serial dilutions containing 72.0, 48.0, 32.0, 20.6, 13.1, 8.7, and 5.8 μg/g (2.5% v/v with 1000 μg/g NOVODOR™ ); and 36.0, 24.0, 16.0, 10.3, 6.5, 4.4, and 2.9 μg/g (1.25% v/v with 1000 μg/g NOVODOR™). Neat samples (without compounds la and lb) and reference substances are prepared as well. The LC 50 S of the paired neat samples are divided by the potentiated LC50 values to give the fold reduction in LC 50 associated with the mixture of compounds la and lb. The results are presented in TABLE 7, infra, and indicate that the crude mixture of compounds la and lb potentiates the insecticidal activity of NOVODOR™ against Leptinotarsa texana.

Perrenial rye grass roots (11 days old) are dipped in the crude mixture of compounds la and lb (1.8 mgs of la and lb per ml) and are allowed to partially dry. One third instar Popillia japonica larva is placed in a tin with several treated roots. After 24 hours, the roots and the larvae are covered with Wooster silt loam. Control roots are dipped in water, and untreated controls consist of larvae placed directly into the loam on day 1. The tins are incubated in the dark at 25°C, and the number of dead larvae are checked after 7, 10, 21, 28, and 36 days and control corrected mortality is reported { (Control survival - Treatment SurvivaiyControl Survival) x 100%}. A total of 25 larvae are used for each treatment. The results, as shown in Table 10, demonstrate that the crude mixture of compounds la and lb are effective against third instar Popilliajaponica.

A caged colony oi Epilachna varivesis adults is maintained on Burpee's bush lima beans in a growth chamber under a 16:8 photoperiod at 80°F and 50% relative humidity. Egg masses are collected and allowed to hatch in a petri dish containing a wet cotton wick and lima bean leaves. After two days, second instar larvae are collected and used for leaf dip bioassays. To perform the bioassay, bean leaves are harvested, and the petiole of a single leaf is pushed through the rubber septum of a florist's tube containing 4 ml of water. The leaves are then dipped in serial dilutions in the range of 0- 12% v/v of the crude material containing compounds la and lb. Once the leaves have dried, 8-10 second instar larvae are placed on each leaf. The insects, leaves, and the florist's tubes are placed in a 22 ounce paper cup, covered with fine mesh. The cups are held in the same growth chamber used fo rearing the beetle colony. Every two days the cups are removed rom the growth chamber, the larvae are censused, and the leaves are replaced with fresh treated leaves. Tests are terminated after 8 days. The results, shown in Table 11, demonstrate the crude mixture of compounds la and lb are active against Epilachna varivesis larvae.

The treatments are applied twice 7 days apart with a backpack CO 2 sprayer equipped with 3 Spray Systems TXVX-12 hollow cone nozzles per row and calibrated to deliver 32 GPA at 3 mph and 56 psi. Each treatment is replicated 4 times on plots two rows (34 inch spacing) by 25 feet in a randomized block design. Leptinotarsa decemlineata adults and larvae counts are made from above without disturbing the foliage over 50 feet of row/plot The results, as shown in Figure 3, demonstrate that a crude mixture of compounds la and lb provide significant synergistic activity with NOVODOR™ on potatoes. At 0.5 quarts of NOVODOR™ per acre, 21% control is observed while at 50 grams of the crude mixture of compounds la and lb per acre, 13% control is obtained. However, when both NOVODOR™ and the crude mixture of compounds la and lb are applied together at these rates, the percent control increased to 81%. Similarly, at 100 grams of the crude mixture of compounds la and lb per acre, 28% control is obtained, while at 0.5 quarts of NOVODOR™ 21% control is seen, but when both NOVODOR™ and the crude mixture of compounds la and lb are applied together at these rates, the percent control increased to 81 %. Furthermore, when the crude mixture of compounds la and lb at 50 grams per acre and NOVODOR™ at 1.0 quart per acre are applied together, the percent control increased to 88%.
