Description: DESCRIPTION NOVEL MICROORGANISM AND INSECTICIDE Background of the Invention Field of the Invention. This invention relates to a novel microorganism belonging to Bacillus thuringiensis serovar japonensis, to an insecticide derived from this novel microorganism, and to DNA coding for the insecticide. Description of the Related Art. The reported activity spectrum of B.t. covers insect species within the order Lepidoptera, many of which are major pests in agriculture and forestry. The activity spectrum also includes the insect order Diptera, which includes mosquitos and black flies. See Couch, T.L. (1980) "Mosquito Pathogenicity of Bacillus thuringiensis var. israelensis," Developments in Industrial Microbiology 22:61-76; Beegle, C.C., (1978) "Use of Entomogenous Bacteria in Agroecosystems," Developments in Industrial Microbiology 20:97-104. Krieg et al. (1983) Z. ang. Ent. 96:500-508, describe a B.t. isolate named Bacillus thuringiensis var. tenebrionis, which is reportedly active against two beetles in the order Coleoptera. These are the Colorado potato beetle, Leptinotarsa decemlineata, and Agelastica alni. In European Patent Application 0 202 739 there is disclosed a novel B.t. isolate active against Coleoptera. It is known as B. thuringiensis var. san diego (B.t.s.d.). U.S. Patent No. 4,966,765 discloses the coleopteran-active Bacillus thuringiensis isolate B.t. PS86B1. European Patent Application 0 337 604 also discloses a novel B.t. isolate active against Coleoptera. Coleopteran-active B.t. strains can be used to control foliar-feeding beetles. The Colorado potato beetle {Leptinotarsa decemlineata), for example, is susceptible to the delta-endotoxin of B.t.s.d. and larvae are killed upon ingesting a sufficient dose of spore/crystal preparation on treated foliage. Strain cells among Bacillus thuringiensis serovar japonensis are known to produce insecticidal proteins that kill lepidopteran larvae. However, none of the strain cells among japonensis are known to produce toxin proteins other than the insecticidal proteins that kill lepidopterous larvae. Thus, no such strain cells have been available for use as an insecticide to kill insects other than lepidopterans. Furthermore, Bacillus thuringiensis san diego and Bacillus thuringiensis tenebrionis have no insecticidal effect on larvae of Anomala cuprea Hope, which are very destructive to firewood, taro, sweet potato, peanut, and the like. The current inventors have found a new type of microorganism belonging to Bacillus thuringiensis serovar japonensis that produces insecticidal proteins to kill coleopterous larvae as distinct from lepidopterous larvae. Brief Summary of the Invention The subject invention concerns a novel Bacillus thuringiensis (B.t.) isolate. The novel B.t. isolate, known as Bacillus thuringiensis serovar japonensis strain Buibui (hereinafter referred to as "B.t. Buibui"), has been found to be active against coleopteran pests including the Japanese beetle. A novel ό-endotoxin gene of the invention encodes an =130 kDa protein. The nucleotide sequence of this gene is shown in SEQ ID NO. 1. The predicted amino acid sequence of the toxin is shown in SEQ ID NO. 2. The subject invention also includes variants of B.t. Buibui which have substantially the same pesticidal properties as B.t. Buibui. These variants would include mutants. Procedures for making mutants are well known in the microbiological art. Ultraviolet light and nitrosoguanidine are used extensively toward this end. Further, the invention also includes the treatment of substantially intact B.t. cells, and recombinant cells containing a gene of the invention, to prolong the pesticidal activity when the substantially intact cells are applied to the environment of a target pest. Such treatment can be by chemical or physical means, or a combination of chemical or physical means, so long as the technique does not deleteriously affect the properties of the pesticide, nor diminish the cellular capability in protecting the pesticide. The treated cell acts as a protective coating for the pesticidal toxin. The toxin becomes available to act as such upon ingestion by a target insect.

Brief Description of the Sequences SEQ ID NO.1 is the composite nucleotide and amino acid sequence of the novel gene of the invention. SEQ ID NO. 2 is the predicted amino acid sequence of the toxin. Detailed Description of the Invention The subject invention pertains to a novel strain of Bacillus thuringiensis which has the highly advantageous property of expressing at least one endotoxin which is toxic to coleopterans. The novel microorganism has been designated Bacillus thuringiensis serovar japonensis strain Buibui (hereinafter referred to as "B.t. Buibui"). The subject invention further pertains to insecticidal toxin obtainable from B.t. Buibui as well as DNA coding for said insecticide. Also disclosed and claimed are microorganisms, other than Bacillus thuringiensis, which have been transformed with B.t. Buibui DNA so that said transformed microbes express a coleopteran-active toxin. A further aspect of the subject invention is the use of a toxin of the subject invention, or a transformed host-expressing a toxin, to control coleopteran pests. Yet a further aspect of the subject invention pertains to plants transformed with a B.t. Buibui DNA coding for toxin active against coleopteran pests. Novel microorganisms according to the present invention, have been deposited internationally, pursuant to the Treaty of Budapest, with the Fermentation Research Institute, Agency of Industrial Science and Technology, Ministry of International Trade and Industry, which is a recognized international depository organization. Culture Deposit No. Deposit Date Bacillus thuringiensis serovar FERM BP-3465 June 26, 1991 japonensis strain Buibui Escherichia coli KBR9207 FERM BP-3929 July 13, 1992 The subject cultures have been deposited under conditions that assure that access . to the cultures will be available during the pendency of this patent application to one determined by the Commissioner of Patents and Trademarks to be entitled thereto under 37 CFR 1.14 and 35 U.S.C. 122. The deposits are available as required by foreign patent laws in countries wherein counterparts of the subject application, or its progeny, are filed. However, it should be understood that the availability of a deposit does not constitute a license to practice the subject invention in derogation of patent rights granted by governmental action. Further, the subject culture deposits will be stored and made available to the public in accord with the provisions of the Budapest Treaty for the Deposit of Microorganisms, i.e., they will be stored with all the care necessary to keep them viable and uncontaminated for a period of at least five years after the most recent request for the furnishing of a sample of a deposit, and in any case, for a. period of at least thirty (30) years after the date of deposit or for the enforceable life of any patent which may issue disclosing the cultures. The depositor acknowledges the duty to replace the deposits should the depository be unable to furnish a sample when requested, due to the condition of the deposits. All restrictions on the availability to the public of the subject culture deposits will be irrevocably removed upon the granting of a patent disclosing them. The invention also includes variants of the subject isolates which variants have genes encoding all or part of a toxin of the invention. Such microbial variants may be isolated or they can be made by techniques well known to persons skilled in the art. For example, UV irradiation can be used to prepare variants of host organisms. Likewise, such variants may include asporogenous host cells which also can be prepared by procedures well known in the art. For example, an asporogenous mutant can be obtained through ethylmethane sulfonate (EMS) mutagenesis of a novel isolate. A small percentage of the asporogenous mutants will remain intact and not lyse for extended fermentation periods; these strains are designated lysis minus (-). Lysis minus strains can be identified by screening asporogenous mutants in shake flask media and selecting those mutants that are still intact and contain toxin crystals at the end of the fermentation. Lysis minus strains are suitable for a cell fixation process that will yield a protected, encapsulated toxin protein. To prepare a phage resistant variant of said asporogenous mutant, an aliquot of the phage lysate is spread onto nutrient agar and allowed to dry. An aliquot of the phage sensitive bacterial strain is then plated directly over the dried lysate and allowed to dry. The plates are incubated at 30°C.. The plates are incubated for 2 days and, at that time, numerous colonies could be seen growing on the agar. Some of these colonies are picked and subcultured onto nutrient agar plates. These apparent resistant cultures are tested for resistance by cross streaking with the phage lysate. A line of the phage lysate is streaked on the plate and allowed to dry. The presumptive resistant cultures are then streaked across the phage line. Resistant bacterial cultures show no lysis anywhere in the streak across the phage line after overnight incubation at 30°C. The resistance to phage is then reconfirmed by plating a lawn of the resistant culture onto a nutrient agar plate. The sensitive strain is also plated in the same manner to serve as the positive control. After drying, a drop of the phage lysate is plated in the center of the plate and allowed to dry. Resistant cultures showed no lysis in the area where the phage lysate has been placed after incubation at 30°C for 24 hours. The variants can also be made using ultraviolet light and nitrosoguanidine by procedures well known in the art. The novel microorganism, B.t. Buibui, specifically exemplified according to the present invention has the following characteristics: 1. Growth in Different Culture Media. This microorganism may be grown and the toxin proteins may be produced in all types of media that can be used for culturing ordinary bacteria. As shown in Figures 1 and 2, the microorganism showed ordinary growth patterns in typical culture media such as NYS, L-broth, and bouillon media. That is, the number of cells began to increase logarithmically after lapse of several hours, and the increase stopped upon lapse of 24 hours. Toxins appeared shghtly after the increase in the number of cells. The quantity of toxins, when measured in the- main band 130 kDa, was 200 to 300 μg/ml medium. 2. Morphological Characteristics. As shown in Figures 3 and 4, the colonies produced have surface gloss on an agar medium, and spread thinly over the agar surfaces without swelling. Peripheral roughs show characteristics of ordinary Bacillus cells. The color of the colonies is light beige. When observed through a scanning electron microscope, both Bacillus thuringiensis serovar japonensis and Bacillus thuringiensis serovar japonensis strain Buibui show spherical crystal proteins. These are distinct from the bipyramid crystals commonly observed with other B.t. cells lethal to lepidopterous larvae. 3. Biochemical Appearance. The following tests have been conducted to evaluate the biochemical characteristics of B.t. Buibui as compared with conventional japonensis strains: Test 1. Serotyping using antibodies produced against flagellar antigens: This is a method for identifying an unknown organism by employing an antibody active to the proteins of flagella of Bacillus organisms, and utilizing an antigen-antibody reaction in which the flagellar proteins of the unknown organism act as the antigens. Japonensis strain is a subspecies classified and recognized as H23 type (/. Invertebr. Pathol. 32:303-309, 1978; /. Invertebr. Pathol. 48:129-130, 1986). B.t. Buibui is reactive with H-antigen of japonensis strain. This property is serologically equivalent to that of japonensis strain. Thus, taxonomically, B.t. Buibui belongs to the same subspecies as japonensis strain. Details of this test are as follows: (1) Preparation of flagellar H-serum: Forty known types of H-antigen standard strains of Bacillus thuringiensis were used. Microorganisms having excellent mobility were selected by using a Craigie tube (0.5% semifluid agar medium), and formalin-killed organisms were prepared. Rabbits were immunized with these organisms. H-serum was prepared by absorbing, from respective antisera, antibodies reactive to Bacillus thuringiensis cell antigens. The cell antigens were prepared by heating them to 100°C and separating the flagella. (2) Identification of H-antigen: Serum types of H-antigen were identified through agglutination reactions on slide glass (Ohba and Aizawa [1978] J. Invertebr. Pathol. 32:303-309). Agglutination values of H-serum were measured through in vitro agglutination reactions (Ohba and Aizawa, supra). (3) Results: Japonensis strain was particularly agglutinated only by the serum for standard strain cells of serovar japonensis (H-antigen 23) among standard sera including 40 known types of flagellar antigens only. The agglutination value of japonensis H-serum for corresponding homo-antigens was 12,800-fold, and the agglutination value thereof for Buibui strain was 6,400-fold. The agglutination value of B.t. Buibui H-serum for homo was 12,800-fold and the agglutination value thereof for japonensis standard strain was 6,400-fold. Thus, the two strain cells are determined to be the same species. Test 2. Insecticidal spectral of crystal proteins produced by japonensis strain and B.t. Buibui: As shown in Table 1, the insecticidal proteins produced by B.t. Buibui showed an insecticidal effect in a concentration of 0.125 to 12.5 μg ml on Anomala cuprea Hope, a coleopteran. However, the insecticidal proteins produced by the japonensis strain did not show an insecticidal effect even in a concentration of 100 μg/ml. As shown in Table 2, the insecticidal proteins produced by japonensis strain showed a high degree of activity with respect to larvae of lepidopterans such as Plutella xylostella, Adoxophyes sp., and Bombyx mori. However, the insecticidal proteins produced byJS.t. Buibui showed little or a very low degree of activity'. These results demonstrate that the two strains cannot be said.to be the same strains. Furthermore, the observance of coleopteran activity, but no lepidopteran activity is quite surprising and unexpected. *Number of samples = 20 larvae in the first instar. Table 2. Insecticidal activities oϊ japonensis strain and Buibui strain with respect to some lepidopterans. Toxin dosage Death rates* (%) Samples (μg 130 kDa protein/ml) Buibui japonensis 100 4 47 3 70 *Number of samples = 50 larvae in the first to third instar. Test 3. Electrophoresis of insecticidal proteins accumulating in the cells of japonensis strain and B.t. Buibui: B.t. Buibui produces, in the cells, spherical crystalline proteins as does japonensis strain (Figures 5 and 6). The crystalline proteins were isolated from the culture medium by a standard method (Goodman, N.S., R.J. Gottfried, M.J. Rogoff [1987] J. Bacterial 34:485). After purification, the proteins were dissolved in a 0.4 N alkali solution, and analyzed through sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). As shown in Figure 7, japonensis strain has a main band at about 76 kDa, and a different band at 52 kDa. B.t. Buibui has a main band at about 130 kDa, and. different bands at 52 kDa and 45 kDa. These electrophoresis patterns clearly show that the two types of crystalline proteins have different ingredients. Test 4. Difference in adoptivity in culture media between japonensis strain and B.t. Buibui: As shown in Table 3, japonensis strain adopts glucose, salicin, and maltose, does not adopt mannose, and adopts cellobiose to a certain degree. B.t. Buibui can adopt all of these substances. These features show that, taxonomically, B.t. Buibui is classified by serotype as japonensis strain, but clearly is a cell different from japonensis strain. Table 3. japonensis Buibui ++ ++ ++ +- + + + + + + + +++ = adopt very well; -f- = adopt well, -. — = adopt; — = do not adopt B.t. Buibui can be cultured using standard art media and fermentation techniques. Specific examples of fermentation media and techniques are provided in the examples which follow. Upon completion of the fermentation cycle, the bacteria can be harvested by first separating the B.t. spores and crystals from the fermentation broth by means well known in the art. The recovered B.t. spores and crystals can be formulated into a wettable powder, liquid concentrate, granules, or other formulations by the addition of surfactants, dispersants, inert carriers and other components to facilitate handling and application for particular target pests. These formulation and application procedures are all well known in the art. DNA containing the toxin gene from B.t. Buibui can be purified from E. coli KBR9207 by standard procedures well known in the art. The toxin gene can be excised from the plasmid DNA by restriction enzyme digestion. This subject invention pertains not only to the specific DNA sequence shown in SEQ ID NO. 1, but also to variations of this sequence which code for an amino acid sequence having activity against coleopteran characteristics of the toxin produced by B.t. Buibui,. These DNA sequences would be expected to have a high degree of homology and, for example, would be expected to- hybridize with each other and/or common probes or primers under high stringency conditions. Similarly, the subject invention pertains not only to the protein having the amino acid sequence shown in SEQ ID NO. 2, but also to equivalent toxins having the same or similar biological activity of the toxin shown in SEQ ID NO. 2. These equivalent toxins may have amino acid homology with the toxin disclosed and claimed herein. This amino acid homology will typically be greater than 50%, preferably be greater than 75%, and most preferably be greater than 90%. The amino acid homology will be highest in certain critical regions of the toxin which account for biological activity or are involved in the determination of three-dimensional configuration which ultimately is responsible for the biological activity. In this regard, certain amino acid substitutions are acceptable and can be expected if these substitutions are in regions which are not critical to activity or are conservative amino acid substitutions which do not affect the three-dimensional configuration of the molecule. For example, amino acids may be placed in the following classes: non- polar, uncharged polar, basic, and acidic. Conservative substitutions whereby an amino acid of one class is replaced with another amino acid of the same type fall within the scope of the subject invention so long as the substitution does not materially alter the biological activity of the compound. Table 4 provides a listing of examples of amino acids belonging to each class. Table 4 Class of Amino Acid Examples of Amino Acids Nonpolar Ala, Val, Leu, He, Pro, Met, Phe, Tip Uncharged Polar Gly, Ser, Thr, Cys, Tyr, Asn, Gin Acidic Asp, Glu Basic Lys, Arg, His — — — -^___.__.__._____-__ M ι__- aB -_--_ ___ In some instances, non-conservative substitutions can also be made. The critical factor is that these substitutions must not significantly detract from the biological activity of the toxin. The genes and toxins according to the subject invention include not only the full length sequences disclosed herein but also fragments of these sequences, or fusion proteins, which retain the characteristic coleopteran activity of the toxins specifically exemplified herein. It should be apparent to a person skilled in this art that genes coding for coleopteran-active toxins can be identified and obtained through several means. The specific genes may be obtained from a culture depository as disclosed herein. Alternatively, these genes, or portions thereof, may be constructed synthetically, for example, .by use of a gene machine. Variations of these genes may be readily constructed using standard techniques for making point mutations. Also, fragments of these genes can be made using commercially available exonucleases or endonucleases according to standard procedures. For example, enzymes such as Bal31 or site-directed mutagenesis can be used to systematically cut off nucleotides from the ends of these genes. Also, genes which code for active fragments maybe obtained using a variety of other restriction enzymes. Proteases may be used to directly obtain active fragments of these toxins. DNA of the subject invention, which codes for coleopteran-active toxin, can be introduced into a wide variety of microbial and plant hosts. Expression of the DNA results, directly or indirectly, in the production and maintenance of the pesticide. With suitable hosts, e.g., Pseudomonas, the microbes can be applied to the situs of coleopteran insects where they will proliferate and be ingested by the insects. The result is a control of the unwanted insects. Alternatively, a microbe hosting the toxin-coding DNA can be treated under conditions that prolong the activity of the toxin produced in the cell. The treated cell then can be applied to the environment of target pest(s). The resulting product retains the toxicity of the B.t. toxin. Where the B.t. toxin-coding DNA is introduced via a suitable vector into a microbial host, and said host is applied to the environment in a living state, it is essential that certain host microbes be used. Microorganism hosts are selected • which are known to occupy the "phytosphere" (phylloplane, phyllosphere, rhizosphere, and/or rhizoplane) of one or more crops of interest. These microorganisms are selected so as to be capable of successfully competing in the particular environment (crop and other insect habitats) with the wild-type microorganisms, provide for stable maintenance and expression of the gene expressing the polypeptide pesticide, and, desirably, provide for improved protection of the pesticide from environmental degradation and inactivation. A large number of microorganisms are known to inhabit the phylloplane (the surface of the plant leaves) and/or the rhizosphere (the soil surrounding plant roots) of a wide variety of important crops. These microorganisms include bacteria, algae, and fungi. Of particular interest are microorganisms, such as bacteria, e.g., genera Pseudomonas, Erwinia, Serratia, Klebsiella, Xanthomonas, Streptomyces, P iizobium, Rhodopseudomonas, Methylophilius, Agrobacterium, Acetobacter, Lactobacillus,Arthrobacter, Azotobacter, Leuconostoc, andAlcaligenes; fungi, particularly yeast, e.g., genera Saccharomyces, Cryptococcus, Kluyveromyces, Sporobolomyces, Rhodotorula, and Aureobasidium. Of particular interest are such phytosphere bacterial species as Pseudomonas syringae, Pseudomonas fluorescens, Serratia marcescens, Acetobacter xylinum, Agrobacterium tumefaciens, Rhodopseudomonas spheroides, Xanthomonas campestris, Rhizobium melioti, Alcaligenes entrophus, and Azotobacter vinlandii; and phytosphere yeast species such as PJiodotorula rubra, R. glutinis, R. marina, R aurantiaca, Cryptococcus albidus, C. diffluens, C. laurentii, Saccharomyces rosei, S. pretoriensis, S. cerevisiae, Sporobolomyces roseus, S. odorus, Kluyveromyces veronae, and Aureobasidium pollulans. Of particular interest are the pigmented microorganisms. A wide variety of ways are available for introducing the B.t. DNA expressing the toxin into the microorganism host under conditions which allow for stable maintenance and expression of the gene. These methods are well known and easily practiced by those skilled in this art. The transformants can be isolated in accordance with conventional ways, usually employing a selection technique, which allows for selection of the desired organism as against unmodified organisms or transferring organisms, when present. The transformants then can be tested for pesticidal activity. The B.t. cells can be treated prior to formulation to prolong the pesticidal activity when the cells are applied to the environment of a target pest. Such treatment can be by chemical or physical means, or by a combination of chemical and/or physical means, so long as the technique does not deleteriously affect the properties of the pesticide, nor diminish the cellular capability in protecting the pesticide. Examples of chemical reagents are halogenating agents, particularly halogens of atomic no. 17-80. More particularly, iodine can be used under mild conditions and for sufficient time to achieve the desired results. Other suitable techniques include treatment with aldehydes, such as formaldehyde and glutaraldehyde; anti-infectives, such as zephiran chloride; alcohols, such as isopropyl and ethanol; various histologic fixatives, such as Bouin's fixative and Helly's fixative (See: Humason, Gretchen. L., Animal Tissue Techniques, W.H. Freeman and Company, 1967); or a combination of physical (heat) and chemical agents that prolong the activity of the toxin produced in the cell when the cell is applied to the environment of the target pest(s). Examples of physical means are short wavelength radiation such as gamma-radiation and X-radiation, freezing, UV irradiation, lyophilization, and the like. The cell will usually be intact and be substantially in the proliferative form when treated, rather than in a spore form, although in some instances spores may be employed. The treated cells generally will have enhanced structural stability which will enhance resistance to environmental conditions. Where the pesticide is in a proform, the method of inactivation should be selected so as not to inhibit processing of the proform to the mature form of the pesticide by the target pest pathogen. For example, formaldehyde will crosslink proteins and could inhibit processing of the proform of a polypeptide pesticide. The method of inactivation or killing retains at least a substantial portion of the bio-availability or bioactivity of the toxin. The cellular host containing the B.t. insecticidal gene may be grown in any convenient nutrient medium, where the DNA construct provides a selective advantage r providing for a selective medium so that substantially all or all of the cells retain the B.t. gene. These cells may then be harvested in accordance with conventional ways. Alternatively, the cells can be treated prior to harvesting. The B.t. or transformed cells may be formulated in a variety of ways. They may be employed as wettable powders, granules or dusts, by mixing with various inert materials, such as inorganic minerals (phyllosilicates, carbonates, sulfates, phosphates, and the like) or botanical materials (powdered corncobs, rice hulls, walnut shells, and the like). The formulations may include spreader-sticker adjuvants, stabilizing agents, other pesticidal additives, or surfactants. Liquid formulations may be aqueous-based or non-aqueous and employed as foams, gels, suspensions, emulsifiable concentrates, or the like. The ingredients may include Theological agents, surfactants, emulsifiers, dispersants, or polymers. Another approach that can be taken is to incorporate the spores and crystals of B.t. Buibui into bait granules containing an attractant and applying these granules to the soil for control of soil-inhabiting Coleoptera. Formulated B.t. Buibui can also be applied as a seed-coating or root treatment or total plant treatment. The pesticidal concentration will vary widely depending upon the nature of the particular formulation, particularly whether it is a concentrate or to be used directly. The pesticide will be present in at least 1% by weight and may be 100% by weight. The dry formulations will have from about 1-95% by weight of the . pesticide while the hquid formulations will generally be from about 1-60% by weight of the solids in the liquid phase. The formulations will generally have from about 10 2 to about 10 4 cells/mg. These formulations will be administered at about 50 mg (hquid or dry) to 1 kg or more per hectare. The formulations can be applied to the environment of the coleopteran pest(s), e.g., plants, soil or water, by spraying, dusting, sprinkling, or the like. Following are examples which illustrate procedures, including the best mode, for practicing the invention. These examples should not be construed as limiting. All percentages are by weight and all solvent mixture proportions are by volume unless otherwise noted. Example 1 - Culturing B.t. Buibui A subculture of B.t. Buibui can be used to inoculate the following medium, a peptone, glucose, salts medium. Bacto Peptone 7.5 g/1 Glucose 1.0 g/1 KH 2 PQ 4 3.4 g/1 K 2 HP0 4 4.35 g 1 Salt Solution 5.0 ml/1 CaCl 2 Solution 5.0 ml/1 Salts Solution (100 ml) MgS0 4 .7H 2 0 • 2.46 g MnS0 4 .H 2 0 0.04 g ZnS0 4 .7H 2 0 0.28 g FeS0 4 .7H 2 0 0.40 g CaCl 2 Solution (100 ml) Ca0..2H 2 0 3.66 g pH 7.2 The salts solution and CaCl 2 solution are filter-sterilized and added to the autoclaved and cooked broth at the time of inoculation. Flasks are incubated at 30°C on a rotary shaker at 200 rpm for 64 hr. The above procedure can be readily scaled up to large fermentors by procedures well known in the art. The B.t. spores and crystals, obtained in the above fermentation, can be isolated by procedures well known in the art. A frequently-used procedure is to subject the harvested fermentation broth to separation techniques, e.g., centrifugation. Example 2 - Further Methods for Culturing B.t. Buibui B.t. Buibui easily grows in culture media commonly used for culturing bacteria, such as L-broth, nutrient broth, and the like, and produces spores and crystalline proteins. Inventors have reviewed highly productive media for culturing B.t. Buibui to produce insecticidal ingredients including the crystalline proteins. First, 3.3 x 10 5 spores were inoculated into an agar medium on a 9 cm petri dish. The crystalline proteins produced in 10 days were observed through a microscope. A medium having MnS0 4 (10-#M) added to L-broth was the most productive, the order of productivity being as follows: L-broth + MnS0 4 > spizizen + amino acid > L-broth > PGSM > spizizen + casamino acid + vitamin > spizizen -f- casamino acid > NYS > NYS + casamino acid. The respective media have the following compositions: L-broth: 10 g of tryptose, 5 g of yeast extract, and 5 g of table salt, all per- 1 liter, and pH = 7.18 to 7.2. Spizizen: 14 g of potassium 1-hydrogen phosphate (K 2 H), 6 g of potassium 2-hydrogen phosphate (KH 2 P0 4 ), 2 g of ammonium sulfate, 0.2 g of magnesium sulfate, 1 g of sodium citrate, and 5 g of glucose, all per 1 liter, and pH = 7.0. NYS: 1.25 g of nutrient broth, 1.25 g of trypton, 0.5 g of yeast extract, 10.3 g of calcium chloride, 20.35 g of magnesium chloride, 1.0 g of manganese chloride, 0.02 g of iron sulfate, and 0.02 g of zinc sulfate, all per 1 liter, and pH = 7.2. NYS + casamino acid: 2.0 g of casamino acid added to the above NYS medium, and pH = 7.2. Next, in preparing an insecticide using the insecticidal crystalline proteins produced by the subject cells and effective on coleopterous larvae, the microorganisms according to the invention are cultured in the various media noted above, or in solid media such as fish meal, soy bean powder and the like, or in wastes from starch or sugar processing such as com syrup and com steep. The cells cultured by the various methods as above are condensed into creamy form. This is appropriately diluted with water or the like to be sprayed as an insecticide. An antiseptic, extender, and the like, may be mixed into the creamy substance by a usual method. The creamy substance may subsequently be reduced to powder form by means of a spray dryer. The above method uses the cells themselves which produce the toxin proteins. However, only the crystalline proteins may be used after culturing the cells until autolysis. The product thus obtained is used as a viable microbe cell preparation since the cells produce spores. The toxin proteins produced by these cells do not show toxicity to Bombyx mori.. Thus, use of the viable microbe cell preparation having spores is not destructive at all to silk culture. Further, the spores may be killed with a suitable compound for use as a killed microbe cell preparation. A method of spraying the above preparation will be described- next. Coleopterous larva to be killed usually live in soil. Thus, the insecticide having the subject cells as an effective ingredient may be sprayed into soil, or may be scattered together with leaf mold which is immediately followed by a mixing operation with a cultivator or the like. A suspension of the above insecticide may be injected directly into soil by using an automatic or manual injector or the like. For this purpose, a fully automatic injector may be installed on a cultivator. Example 3 - Insecticidal Activity of B.t. Buibui with Respect to Anomala cuprea Hope, a Coleopteran As noted hereinabove, Buibui strain shows a very high degree of insecticidal activity not reported heretofore, with respect to Anomala cuprea Hope. The insecticidal activity- of B.t. Buibui was examined using larvae of Anomala cuprea Hope in the first to third instars. The activity was evaluated as follows: 2 ml of water containing insecticidal ingredients was added to 2 g of dry leaf mold. The mixture was placed in a plastic cup. The larvae were then placed one after another and kept therein for a predetermined time. The insecticidal ingredients included a culture solution of Buibui strain (i.e., a solution containing Buibui strain cells) and crystalline toxin proteins isolated from the culture solution and purified. The insecticidal activity of each ingredient was examined. It is to be noted that the death rate is the number of dead larvae divided by the total number of larvae. Figure 8 shows how the death rate varies with lapse of time depending on quantity of the insecticidal ingredient (toxin) comprising the culture solution. It will bee seen that 100% death rate is obtained with a low toxin dosage of 0.125 μg/ml and with a high dosage of 12.5 μg/ml. It has been found, however, that twice the time is taken before all the larvae were killed in the case of a low concentration. The term "control" in Figure 8 signifies variations occurring when only water containing no toxin is apphed. As shown in Table 5, the insecticidal ingredient comprising the crystalline proteins isolated and purified, showed insecticidal activity on its own. No insecticidal activity was detected with crystals 0.1 μg/ml. However, 100% death rate was obtained, though slowly, when the culture solution containing 130 kDa proteins in 1 μg/ml was applied to Anomala cuprea Hope as noted hereinabove (Figure 8). This is considered due to the fact that spores present in the cells cooperate with the crystalhne proteins in Anomala cuprea Hope to show the high degree of activity, and not that activity is lost due to denaturation of the proteins in the course of purification of the crystalhne proteins. Thus, the insecticide may contain the cells. Table 5.

The cells were cultured in NYS. Example 4 - Insecticidal Effects of B.t. Buibui on Larvae of Other Coleopterans As shown in Table 6, Buibui strain showed a higher degree of insecticidal activity with respect also to Anomala rufocuprea Motschulsky, Anomala schoenfeldti Ohaus, apart from Anomala cuprea Hope. Thus, Buibui strain is expected to show insecticidal effect on larvae of several other Minela splendens. Thus, the insecticide is not limited in apphcation to these three types of coleopterans.

The crystals were purified from cells cultured in NYS. The number of samples was 10. The term "control" above shows results obtained when only water containing no toxin is apphed (in a comparative test). Example 5 - Insecticidal Effects on Other Coleopterans The insecticidal activity of Buibui strain was examined, using larvae in the first instar of Anomala albopilosa, larvae in the first instar of Anomala daimiana, larvae in the first instar of Minela splendens, larvae in the first instar of Popillia japonica, and larvae in the second instar of Blitoperiha orientalis. The samples were young larvae hatched from eggs of adults collected outdoors and temporarily bred in a commercially available leaf mold. The testing method was as follows: 1 gram of leaf mold dried and sterilized in a dry oven at 160°C for 60 minutes was weighed with a cup having a lid and a capacity of about 30 ml. Buibui culture in a predetermined concentration was mixed into the cup and sufficiently stirred, and then one larva was placed therein. A plurality of such mixtures were prepared, and bred in a thermostatic chamber at 25°C. The death rate was checked on the 7th, 14th, and 21st days to determine potency of Buibui. The results are shown in Table 7. Table 7. Toxin dosage Death rates (%) 130 kDa protein „ , ., „ , „„ Λ Larvae μg/g leaf mold 7th 14th 21st da ^ The number of samples were 8 and 5 for Anomala daimiana and Blitopertha orientalis, respectively, and 10 for all the others. As noted above, Buibui strain showed insecticidal activity with respect to Anomala albopilosa, Anomala daimiana, Minela splendens, Popillia japonica, and Blitopertha orientalis. In the case of Anomala daimiana, the death rate was 70% after 21 days, which is lower than the rates of the other insects. However, no increase in the weight was observed, and it was obvious that the larvae of Anomala daimiana were to die in due course. Thus, although some delays were observed, the cessation of food intake is considered equivalent to death. Particularly important is the insecticidal property to kill what are known as Japanese beetles, which are causing a serious problem in the United States. Having determined the activity with respect to several coleopterans, the fact that the activity with respect to Popillia, Minela, and Blitopertha species as well as Anomala species suggests that the subject cells are not limited in apphcation to those insects listed in Tables 6 and 7 but are applicable to a wide variety of coleopteran pests. Example 6 - Activity of Beta-Exotoxin Some of Bacillus strain cells excrete into culture media beta-exotoxin, which is a nucleotide derivative. It has an insecticidal effect similar to that of toxin proteins. Beta-exotoxin shows teratogenic action with respect to larvae of house flies, which provides a basis for evaluating the activity of beta-exotoxin. However, as shown in Table 8, when a supernatant of culture was prepared from a medium of Buibui strain by a usual method and applied to house flies, Buibui strain showed no teratogenesis with their pupation rate and eclosion rate remaining unaffected. When the above treating medium of Buibui strain was apphed to Anomala cuprea Hope, its larvae remained ahve after lapse of 14 days as shown in Table 9. The results of this test show that the insecticidal effect of Buibui strain on Anomala cuprea Hope does not depend on beta-exotoxin. That is, beta-exotoxin does not exist to the extent of influencing the test results. Table 8.

Example 7 - Insertion of Toxin Gene Into Plants One aspect of the subject invention is the transformation of plants with genes coding for a coleopteran-active toxin. The transformed plants are resistant to attack by coleopterans. Genes coding for coleopteran-active toxins, as disclosed herein, can be inserted into plant cells using a variety of techniques which are well known in the art. For example, a large number of cloning vectors comprising a replication system in E. coli and a marker that permits selection of the transformed cells are available for preparation for the insertion of foreign genes into higher plants. The vectors comprise, for example, pBR322, pUC series, M13mp series, pACYC184, etc. Accordingly, the sequence coding for the B.t. toxin can be inserted into the vector at a suitable restriction site. The resulting plasmid is used for transformation into E. coli. The E. coli ceUs are cultivated in a suitable nutrient medium, then harvested and lysed. The plasmid is recovered. Sequence analysis, restriction analysis, electrophoresis, and other biochemical-molecular biological methods are generally carried out as methods of analysis. After each manipulation, the DNA sequence used can be cleaved and joined to the next DNA sequence. Each plasmid sequence can be cloned in the same or other plasmids. Depending on the method of inserting desired genes into the plant, other DNA sequences may be necessary. If, for example, the Ti or Ri plasmid is used for the transformation of the plant cell, then at least the right border, but often the right and the left border of the Ti or Ri plasmid T-DNA, has to be joined as the flanking region of the genes to be inserted. The use of T-DNA for the transformation of plant cells has been intensively researched and sufficiently described in EP 120516; Hoekema (1985) In: The Binary Plant Vector System, Offset-durkkerij Kanters B.V.. Alblasserdam, Chapter 5; Fraley et al, Crit. Rev. Plant Set 4:1-46; and An et al (1985) EMBO J. 4:277-287, Once the inserted DNA has been integrated in the genome, it is relatively stable there and, as a rule, does not come out again. It normally contains a selection marker that confers on the transformed plant cells resistance to a biocide or an antibiotic, such as kanamycin, G 418, bleomycin, hygromycin, or chloramphenicol, inter alia. The individually employed marker should accordingly permit the selection of transformed cells rather than cells that do not contain the inserted DNA. A large number of techniques are available for inserting DNA into a plant host cell. Those techniques include transformation with T-DNA using Agrobacterium tumefaciens or Agrobacterium rhizogenes as transformation agent, fusion, injection, or electroporation as well as other possible methods. If agrobacteria are used for the transformation, the DNA to be inserted has to be cloned into special plasmids, namely either into an intermediate vector or into a binary vector. The intermediate vectors can be integrated into the Ti or Ri plasmid by homologous recombination owing to sequences that are homologous to sequences in the T-DNA. The Ti or Ri plasmid also comprises the vir region necessary for the transfer of the T-DNA. Intermediate vectors cannot replicate themselves in agrobacteria. The intermediate vector can be transferred into Agrobacterium tumefaciens by means of a helper plasmid (conjugation). Binary vectors can replicate themselves both in E. coli and in agrobacteria. They comprise a selection marker gene and a linker or polylinker which are framed by the right and left T-DNA border regions. They can be transformed directly into agrobacteria (Holsters et al. [1978] Mol Gen. Genet. 163:181-187). The agrobacterium used as host cell is to comprise a plasmid carrying a vir region. The vir region is necessary for the transfer of the T-DNA into the plant cell. Additional T-DNA may be contained. The bacterium so transformed is used for the transformation of plant cells. Plant explants can advantageously be cultivated with Agrobacterium tumefaciens ox Agrobacterium rhizogenes for the transfer of the DNA into the plant cell. Whole plants can then be regenerated from the infected plant material (for example, pieces of leaf, segments of stalk, roots, but also protoplasts or suspension-cultivated cells) in a suitable medium, which may contain antibiotics or biocides for selection. The plants so obtained can then be tested for the presence of the inserted DNA. No special demands are made of the plasmids in the case of injection and electroporation. It is possible to use ordinary plasmids, such as, for example, pUC derivatives. The transformed cells grow inside the plants in the usual manner. They can form germ cells and transmit the transformed trait(s) to progeny plants. Such plants can be grown in the normal manner and crossed with plants that have the same transformed hereditary factors or other hereditary factors. The resulting hybrid individuals have the corresponding phenotypic properties. Example 8 - Cloning of Novel B. thuringiensis Genes Into Insect Viruses A number of viruses are known to infect insects. These viruses include, for example, baculoviruses and entomopoxviruses. In one embodiment of the subject invention, ant-active genes, as described herein, can be placed with the genome of the insect virus, thus enhancing the pathogenicity of the virus. Methods for constructing insect viruses which comprise B.t. toxin genes are well known and readily practiced by those skilled in the art. These procedures are described, for example, in Merryweather et al. (Merryweather, A.T., U. Weyer, M.P.G. Harris, M. Hirst, T. Booth, R.D. Possee (1990) J. Gen. Virol 71:1535-1544) and Martens et al. (Martens, J.W.M., G. Honee, D. Zuidema, J.W.M. van Lent, B. Visser, J.M. Vlak (1990) Appl. Environmental Microbial 56 (9): 2764-2770). It should be understood that the examples and embodiments described herein are for iUustrative purposes only and that various modifications or changes in hght thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this apphcation and the scope of the appended claims.
