ELECTROPHORETIC DETECTION OF PARASITISM BY DRYINIDAE IN TYPHLOCYBINAE LEAFHOPPERS (HOMOPTERA: AUCHENORRHYNCHA)
Authors: Demichelis Stefano , Manino Aulo 
Published: November 2009

AbstractNine species of the subfamily Typhlocybinae (Auchenorrhyncha: Cicadellidae) were collected from Corylus avellana L., Solatium tuberosum L., and Vitis vinifera L. Seven species were parasitized by Dryinidae, among which Alebra coryli Le Quesne 1977 and Edwardsiana staminata (Ribaut, 1931) were recognized for the first time. Clearly parasitized and apparently unparasitized leafhoppers and dissected dryinid larvae were assayed by polyacrylamide gel electrophoresis. The α-glycerophosphate dehydrogenase (α-GPD) enzyme system proved to be a reliable tool for indicating the presence of dryinids in all sampled species: the parasitized adults always showed a fast band, which was absent in unparasitized adults. The α-GPD was a reliable enzyme system to detect dryinids at an early stage of their development but not to discriminate among dryinid species. The occurrence of dryinids in the males of A. coryli and Zygina rhamni Ferrari, 1882 was also pointed out by the change of their colouration.

Authors: Hamilton K.G.A. 
Published: November 2009

AbstractThe North American genusCeratagalliaKirkaldy, 1907 is redefined to include subgenusAceratagalliaKirkaldy, 1907 (=IoniaBall, 1933, syn.nov.) with 78 species in two subgenera. Two additional new species are unplaced to subgenus:C. aceratafrom Oregon, andC. emarginatafrom Mexico. The typical subgenusCeratagalliahas 30 species, includingC. gillettei(Osborn & Ball, comb.nov.),C. sordida(Oman, comb.nov.), and two new speciesC. anafrom Mexico andC. viperafrom Washington state. SubgenusAceratagalliahas 46 species, all new combinations underCeratagallia. The economic "species" formerly known as "sanguinolenta" is divided into the Canadian clover leafhopperC. humilis(Oman) and the American clover leafhopperC. agricolasp.nov. Other new taxa in subgenusAceratagalliainclude 18 new species and seven new subspecies:alaskana(ssp. ofsiccifolia)from Alaska;omanion the Pacific coast from Oregon to British Columbia;clinoandlophiafrom the Oregon interior;compressa(ssp. ofsiccifolia),gallus,modesta,okanagana, andzacki(ssp. ofnanella) from intermontane valleys of the Pacific northwest and southwestern mountains;interior(ssp. ofhumilis) androssifrom the Sonoran subregion;australis(ssp. ofnanella),coma,ebena,entoma,falcata,oionus, andvenosafrom Mexico and Texas;alvarana(ssp. ofhumilis),cerea,cristula,harrisi, semiarida, andviatorwidespread between the Appalachian and Rocky Mountains; andwhitcombi(ssp. ofrobusta) from Florida to Arizona. Four former species are reduced to subspecies:compactaOman andpoudrisOman inC. robusta(Oman),helveolaOman inC. cinerea(Osborn & Ball), andtruncataOman inC. humilis. The taxa are keyed and illustrated, and their phylogeny is discussed.
ISOLATION, CHARACTERIZATION, AND CULTURE OFBACILLUS THURINGIENSISFROM SOIL AND DUST FROM GRAIN STORAGE BINS AND THEIR TOXICITY FORMAMESTRA CONFIGURATA(LEPIDOPTERA: NOCTUIDAE)
Authors: Morris O.N. , Converse V. , Kanagaratnam P. , Coté J.-C. 
Published: November 2009

AbstractOne hundred and twoBacillus thuringiensisBerliner strains isolated from six different types of Canadian soil and dust from different grain storage bins were cultured in shake flasks containing Great Northern White Bean (GNWB) protein concentrate (48.6% protein) as the main nitrogen source and dextrose as the main carbohydrate source. The resulting endotoxins were bioassayed against the bertha armyworm,Mamestra configurataWlk. Thirty-three percent of soil and 66% of grain dust samples were positive forB. thuringiensis. The bacterium was found most frequently in organic-rich soil. The four most toxic soil isolates (which were seven to 15 times more toxic than the international standard, HD1-S-1980), and two nontoxic grain dust isolates were characterized by serological typing, biochemical analysis, carbohydrate utilization, plasmid profile analysis, protein profile analysis using sodium dodecyl sulfate – polyacrylamide gels, and polymerase chain reaction. Four isolates were determined to be subsp.kurstakicontaining 130–140 and 63–65 kDa proteins, and two isolates (tested for comparison) were subsp.canadensiscontaining 31 and 38 kDa proteins. Nonpyramidal-crystal-producing strains did not grow well in culture media containing GNWB, degossypellized cotton seed meal (61% protein), defatted soy flour (55% protein), or peptone as nitrogen sources. Excess of GNWB protein concentrate in shake flask culture media (30 g/L) inhibited bacterial growth and reduced the toxicity of isolate A1.2/72 subsp.kurstaki, which was the most toxic soil isolate. Isolate A1.2/72, which was 15 times more toxic for bertha armyworm larvae than the international standard (HD1-S-1980), contained threecry1Agenes (cry1Aa,cry1Ab, and cry1Ac), whereas HD-1 lacked thecry1Abgene. This strain was synergistic with strain HD-551 subsp.kenyae(cry1A,cry2A, andcry1Bgenes) but not with HD-133 subsp.aizawai(cry1Ab,cry1B,cry1C, andcry1Dgenes) when the strains were cultured together in a cotton seed meal medium and fed toM. configurata. The growth rate, economic yield, and toxicity of the new isolate, A1.2/72, produced in a 14-L laboratory fermenter declined when the fermentation ingredients were tripled. We believe that the indigenous strain A1.2/72 warrants further research development for bertha armyworm control.

CUTICULAR HYDROCARBON ANALYSIS OF THE AQUATIC BEETLEAGABUS ANTHRACINUSMANNERHEIM (COLEOPTERA: DYTISCIDAE)
Authors: Alarie Yves , Joly Hélène , Dennie Danielle 
Published: November 2009

AbstractRelatively little information concerning the cuticular hydrocarbon composition of aquatic insects is known. The cuticular hydrocarbons of the aquatic beetleAgabus anthracinusMannerheim have been identified with the aid of a gas chromatograph coupled to a mass spectrometer. The cuticular hydrocarbon profile comprisesn-alkanes (46.8%),n-alkenes (27.1%), and methylalkanes (25.9%) and is basically similar to that of terrestrial Coleoptera. However, the hydrocarbons ofA. anthracinusdiffer in that (i) the shorter chainn-alkanes are present in higher proportion, (ii) there is a relatively lower abundance of methylalkanes, and (iii) the proportion ofn-alkenes is significantly higher.
EFFECTS OF CLIMATE AND FOREST STRUCTURE ON DURATION OF FOREST TENT CATERPILLAR OUTBREAKS ACROSS CENTRAL ONTARIO, CANADA
Authors: Roland Jens , Mackey Brendan G. , Cooke Barry 
Published: November 2009

AbstractWe examined the effect of forest structure and climate on large-scale and long-term patterns of outbreaks of forest tent caterpillar,Malacosoma disstriaHbn., across central Ontario. This was done using previously published data on outbreak duration and forest heterogeneity, combined with high-resolution climatic data simulated by the recently developed Ontario Climate Model. Our analysis, which eliminates some of the spatially confounding effects of forest structure and climate, suggests that both the predicted long-term temperature minimum for the coldest month and the predicted growing degree-days in the first 6 weeks of the growing season are important determinants of outbreak duration, with colder weather being associated with shorter outbreaks. Forest heterogeneity accounts for more variation in outbreak duration than either of the climatic variables.
EVALUATION OF COMMERCIALLY PRODUCED TRICHOGRAMMA SPP. (HYMENOPTERA: TRICHOGRAMMATIDAE) FOR CONTROL OF TOMATO PINWORM, KEIFERIA LYCOPERSICELLA (LEPIDOPTERA: GELECHIIDAE), ON GREENHOUSE TOMATOES
Authors: Shipp J.L. , Wang K. , Ferguson G. 
Published: November 2009

AbstractStudies were conducted to evaluate the ability of six commercially available species of Trichogramma to parasitize eggs of tomato pinworm (TPW), Keiferia lycopersicella (Walsingham), and their potential use for biological control of TPW eggs. Of the six species, Trichogramma pretiosum Riley and Trichogramma brassicae Bezdenk parasitized the most TPW eggs (40–50%). Further studies assessed the effectiveness of T. pretiosum and T. brassicae as biological control agents for TPW eggs under controlled environmental conditions which simulated conditions that could be found during the greenhouse crop production season. Trichogramma pretiosum caused significantly higher mortality of TPW eggs than did T. brassicae at all parasitoid to host egg (P:H) ratios. Mortality caused by host feeding and stinging increased significantly with increasing P:H ratios for both species. Parasitism by T. pretiosum on TPW eggs was reduced significantly and mortality caused by feeding and stinging increased significantly at 28 °C, compared with those at 20 and 25 °C. No differences were found in parasitoid-induced mortality when T. pretiosum were offered 1-, 2-, or 3-day-old TPW eggs, but parasitoid-induced mortality was reduced significantly when parasitoids were offered 4- and 5-day-old TPW eggs. Based on these trials, a P:H ratio of between 1:1 and 10:1 is recommended for inundative releases of T. pretiosum for control of TPW on greenhouse tomatoes.
ASSOCIATION BETWEEN A NATIVE SPITTLEBUG (HOMOPTERA: CERCOPIDAE) ON MONTEREY PINE AND AN INTRODUCED TREE PATHOGEN WHICH CAUSES PITCH CANKER DISEASE
Authors: Storer Andrew J. , Wood David L. , Wikler Karen R. , Gordon Thomas R. 
Published: November 2009

AbstractJuvenile Monterey pines,Pinus radiataD. Don (Pinaceae), in a native stand on the Monterey Peninsula, California, exhibited wilted green shoots in the spring of 1996. The pitch canker fungus,Fusarium subglutinans(Wollenweb. & Reinking) P.E. Nelson, Toussoun & Marasas f.sp.pini, was subsequently isolated from 95% of these shoots. Spittle masses produced byAphrophora canadensisWalley were observed on the symptomless shoots of many of these trees. The pitch canker fungus was isolated from the feeding sites of this insect on 55% of symptomless shoots, and from shoot sections adjacent to these feeding sites on 29% of the shoots. Shoots with spittlebugs feeding on them in May 1996 were more likely to develop pitch canker disease by September 1996 and March 1997 than shoots without spittlebugs. Shoots with spittle masses in March 1997 were as likely to develop pitch canker disease by May and August 1997 as shoots without spittle masses, but the origin of the infection was most likely whereA.canadensisfeeding had taken place. In a controlled test, the incidence of pitch canker on shoots of potted Monterey pines was dependent on the presence of a spittlebug and a spore suspension of the pathogen. Thus, both field observations and controlled studies show an association between nativeA.canadensisand the introduced pitch canker pathogen. The role ofA.canadensisin the epidemiology of pitch canker disease remains to be determined.
PHYLOGENETIC RELATIONSHIPS OF NEARCTIC COLYMBETINAE (COLEOPTERA: ADEPHAGA: DYTISCIDAE) BASED ON CHAETOTAXIC AND POROTAXIC ANALYSIS OF HEAD CAPSULE AND APPENDAGES OF LARVAE
Authors: Alarie Yves 
Published: November 2009

AbstractAn analysis of the primary setae and pores (campaniform sensilla) of first instars of 32 species of Colymbetinae, 61 species belonging to other dytiscid subfamilies, and seven species belonging to other families of Hydradephaga was performed to deduce the ancestral system of primary setae and pores of the head capsule and head appendages of Colymbetinae. Sixty-one setae and 46 pores have been assigned to the ground-plan pattern of the colymbetine larva, 27 setae and 20 pores on the head capsule and 34 setae and 26 pores on the cephalic appendages. The pattern proposed for the Colymbetinae is remarkably consistent and similar to the condition observed within the Carabidae. However, members of the Colymbetinae differ strongly from those of Hydroporinae which are characterized by several secondary losses. A preliminary phylogenetic reconstruction of the relationships of colymbetine genera studied based on 41 larval features suggests that the Nearctic fauna includes two monophyletic lineages: (1) (Agabus Leach + Ilybius Erichson) + Agabinus Crotch, and (2) {[Colymbetes Clairville + (Rhantus Dejean + Neoscutopterus Balfour-Browne)] + Matus Aubé}.
SAMPLING PLANT BUGS, LYGUS SPP. (HETEROPTERA: MIRIDAE), IN CANOLA TO MAKE CONTROL DECISIONS
Authors: Wise I.L. , Lamb R.J. 
Published: November 2009

AbstractPlant bugs in the genus Lygus are pests of canola (Brassica napus L. and Brassica rapa L.) in western Canada and may require insecticidal control. Sweep-net sampling of field plots and commercial fields in southern Manitoba between 1988 and 1995 was used to develop sequential sampling plans for plant bugs in canola to facilitate control. The variance–mean relationships for plant bug catches were defined by Taylor’s power law, and the parameters of the relationships were the same for field plots and commercial fields. Sampling units of 10, 20, 50, and 100 sweeps per sample had variance–mean relationships with the same slope but different intercepts and required different minimal sample sizes. Samples taken at two crop stages had similar variance–mean relationships, but at a later crop stage the intercept of the relationship differed and the parameters were estimated with less precision. Samples taken in two ways along the edges of commercial fields and at various distances into the fields all gave similar estimates of plant bug density, justifying the use of edge sampling. Experienced samplers caught more plant bugs than inexperienced ones, although the difference was primarily due to the number of nymphs rather than adults that were collected, and this difference was less pronounced in the edge samples. Sweep-net sampling collected less than 10% of the plant bugs present in the sampling area. Sequential decision plans are presented for four sampling units and three crop stages. Sampling commercial canola with a sweep net to make decisions on the need to control plant bugs can be completed in as little as 28–35 min. The sampling is most efficiently conducted with a sampling unit of 10 or 20 sweeps taken along the edge of a field. In an independent test of the sampling method, plant bug densities were classified correctly in relation to the need for control in 20 fields using the minimum sample size.

TACHINIDAE (DIPTERA) PARASITOIDS OF BERTHA ARMYWORM (LEPIDOPTERA: NOCTUIDAE)
Authors: O’Hara James E. 
Published: November 2009

AbstractThe bertha armyworm, Mamestra configurata Walker, causes periodic but severe damage to canola crops in North America, particularly in the Canadian provinces of Alberta, Saskatchewan, and Manitoba. This paper provides information on the tachinid flies (Tachinidae: Diptera) recorded from bertha armyworm in North America. A key to adults is provided for separation of the genera, and each species known from bertha armyworm is characterized with respect to recognition, biology (including hosts), and distribution. The species included are Athrycia cinerea (Coquillett), Blondelia sp., Chetogena claripennis (Macquart) species complex, Chetogena tachinomoides (Townsend) (new record), Eurithia consobrina (Meigen), Exorista mella (Walker), Lespesia archippivora (Riley), Panzeria ampelus (Walker), Phryxe pecosensis (Townsend), Phryxe vulgaris (Fallén), Spallanzania hebes (Fallén) (new record), Winthemia rufopicta (Bigot), and Winthemia quadripustulata (Fabricius). Eurithia consobrina is a Palearctic species that has been introduced into Canada for control of M. configurata but is probably not established; it is included here in the event it is introduced again and establishment is achieved.
REARING DELPHASTUS CATALINAE (COLEOPTERA: COCCINELLIDAE): PRACTICAL EXPERIENCE AND A MODELING ANALYSIS
Authors: Pickett C.H. , Casanave K.A. , Schoenig S.E. , Heinz K.M. 
Published: November 2009

AbstractDelphastus catalinae (Horn) (Coleoptera: Coccinellidae) was mass reared to support field studies addressing augmentation and colonization for control of Bemisia argentifolii Bellows and Perring (Homoptera: Aleyrodidae) in southern California. Beetles were reared on B. argentifolii infested poinsettia plants grown inside greenhouses located in northern California. Potted plants, reared from rooted cuttings, were cycled through the rearing system over ca. a 12-week period, then discarded. A total of 174 245 adult beetles were harvested over a 20-week period. Each plant averaged 46 adult beetles (range 21–89) over the same period of time. Harvesting strategies were investigated using a computer simulation model based upon published and hypothesized reproduction and survivorship parameters. Results suggest that removal of approximately 50% of adults per week produced a stable and maximum production of beetles. Actual harvest rates were between 40 and 60% of available beetles. The cost of producing each adult was estimated at US$0.22, with the major cost being labor at 86% of the total.

EVALUATION OF A NATURAL RUBBER SLEEVE STOPPER AS A CONTROLLED-RELEASE SUBSTRATE FOR USE IN STUDIES OF SEX-PHEROMONE-MEDIATED MATING DISRUPTION OF THE SPOTTED TENTIFORM LEAFMINER
Authors: Trimble R.M. , Tyndall C.A. , McGarvey B.D. 
Published: November 2009

AbstractNatural rubber sleeve stoppers were impregnated with 10 mg of (E)-10-dodecen-1-yl-acetate, the major component of spotted tentiform leafminer,Phyllonorycter blancardella(F.), pheromone. In the laboratory, there was a linear decline in the amount of pheromone remaining on stoppers during 8 weeks of exposure to 10, 15, 20, and 25 °C. At 30 and 35 °C, the relationship was curvilinear and could be described using a second-order polynomial equation. The estimated rate of evaporation ranged from 0.03 mg/day at 10 °C to 0.08 mg/day at 25 °C; the rate of evaporation at 30 and 35 °C varied with the time since first exposure. There was a linear decline in the amount of pheromone remaining on stoppers during 8 weeks of exposure to fluctuating temperature regimes with average temperatures of 10 °C (i.e., 5–15 °C) and 20 °C (i.e., 15–25 °C). At a fluctuating regime with an average temperature of 30 °C (i.e., 25–35 °C), the relationship was curvilinear and could be described using a second-order polynomial equation. The estimated rate of evaporation was 0.02 and 0.09 mg/day at 5–15 and 15–25 °C, respectively; the estimated daily rate of evaporation at 25–35 °C varied with the time since first exposure. In an orchard, the estimated average rate of evaporation of pheromone from stoppers ranged from 0.05 to 0.31 mg/day and did not vary significantly with temperature. During the first 4 weeks of exposure in an orchard, the observed rate of evaporation was up to 4.4-fold greater than the rate predicted using the relationship between evaporation rate and constant temperatures observed in the laboratory. The potential for using natural rubber sleeve stoppers as controlled-release substrates in studies of sex-pheromone-mediated mating disruption ofP.blancardellais discussed.

BIOLOGY OF CYPHOCLEONVS ACHATES (COLEOPTERA: CURCULIONIDAE), PROPAGATED FOR THE BIOLOGICAL CONTROL OF KNAPWEEDS (ASTERACEAE)
Authors: Wikeem Brian M. , Powell George W. , Sturko Allen 
Published: November 2009

AbstractCyphocleonus achates (Fahraeus) is a weevil used for the biological control of diffuse knapweed, Centaurea diffusa Monnet Del La Marck, and spotted knapweed, Centaurea maculosa Monnet Del La Marck, in North America. This research provided specific information on the biology of this insect in British Columbia. Adult weevils were released at six densities (1, 2, 4, 8, 16, and 32 male–female pairs) in each of 2 years into plots containing spotted knapweed. Larvae per plant, larval mass, larval survival, adult emergence, and air temperature were measured. Larval production increased with the release density of weevils in both the 1992 cohort and the 1993 cohort. Larval mass did not differ between years. Larval mass also did not vary with the release density of adults or the number of larvae per root. Larval survival of the 1993 cohort ranged from 17 to 48%, whereas that of the 1994 cohort ranged from 0 to 91%. Adult emergence began after the accumulation of 726–1144 degree-days. For both cohorts the date of first emergence occurred earlier, as the average number of larvae per plant increased for both cohorts. Increasing competition for food or space in the roots can induce early emergence. Sex ratios did not vary with date of emergence or release density of adult weevils. Adult emergence increased with the release density in the 1992 cohort, suggesting the average larval densities did not exceed the carrying capacity of the roots. The peak emergence rate increased with the release density in the 1992 cohort, but not in the 1993 cohort because of lower larval survival.
