Results from this study provide experimental data on mechanisms of food dispersal in monodomous and polydomous colonies of ants and may be important for increasing the efficacy of management strategies against T. sessile and other pest ant species. Greenhouse and growth chamber grown plant tissues were fed to first-instar larvae of corn earworms, Helicoverpa zea (Boddie) and fall armyworms Spodoptera frugiperda (J.E. Sorghum excised leaves and stalk pith Sorghum bicolor (L.) Moench (Poales: Poaceae) from near isogenic brown midrib (bmr) 6 and 12 mutants lines, which have lowered lignin content and increased lignocellulosic ethanol conversion efficiency, were examined for insect resistance relative to wild-type (normal BTx623). The sex ratio (proportion of females) of the parasite progeny decreased with an increase in host age. There were significant negative associations among larval size classes: small larvae (<12 mm) occurred less frequently with large larvae (>15 mm) than expected by chance, and large larvae were alone in quadrats more frequently than other size classes. Although the B. bassiana product (min. Here, we isolated and characterized cDNA of the cricket Teleopgryllus emma (Ohmachi & Matsuura) (Orthoptera: Gryllidae) and studied mRNA expression pattern using real time-polymerase chain reaction. The extracts of N. tabacum, Ca. From above, cucumber leaf was the preference to population development of both F. occidentalis and F. intonsa compared with tomato leaf. Therefore, our findings provide a basis for further studies of the host location behavior of this and other species of parasitic wasp. The darkling beetle, Sternoplax souvorowiana (Reitter) (Coleoptera: Tenebrionidae), is flightless and lives in the Guerbantonggut desert in northwestern China. Larval survival and oviposition behavior of three genotypes of diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), (homozygous Cry1Ac-susceptibile, Cry1Ac-resistant, and their F1 hybrids), on transgenic Bacillus thuringiensis (Bt) broccoli expressing different levels of Cry1Ac protein were evaluated in laboratory. This will count as one of your downloads. Hence, information on the species composition and pest status of the fruit fly species is urgent to plan management strategies in the area. The frequency of C. hilaris in cotton (89.47%) was significantly higher than in peanut (7.02%) or corn (3.51%). All susceptible P. xylostella larvae died on all Bt plants, while resistant larvae could survive on broccoli, which expresses low Cry1Ac protein under greenhouse conditions. The results indicated that BmPGRP-S2 participates in the signal transduction pathway of B. mori. The aphids species identified were Rhopalosiphum padi (Linnaeus 1758) and Sitobion avenae (Fabricius 1775). Real-time quantitative polymerase chain reaction detected the relative transcription of the HSP70 gene in larvae and the transcription of A. c-nigrum in response to high temperatures. The first two antennal segments, scape and pedicel, are reinforced by some bristles and have different types of sensillae, including trichoid I, II, S; basiconic II; and sensilla chaetica in different numbers on different host fruit species. This kinetic model prediction could be useful in designing the thermal treatment protocol for controlling C. cephalonica in walnuts. However, the high rainfall on Reunion Island limits the long-term efficiency of the bait; in addition, this method cannot be used for large chayote trellises, because corn borders cannot be planted around them. The final number of larger grain borer in the cassava varieties varied by about sixfold with 63 in 01/0040 and 379 in 01/1368. Such enzymes are often synthe-sized by free living microorganisms or endosymbionts that live in the gut of some animals, including certain phytophagous insects. The cicada Meimuna mongolica (Distant) (Hemiptera: Cicadidae) is one of the most important pests of economic forest in Guanzhong Plain of Shaanxi Province, China. Experienced users in our laboratory routinely sex 8–10 beetles per minute. Host mortality also decreased gradually as the pupal age increased. These new markers will be instrumental for the assessment of gene flow across multiple contact zones in Kikihia. These new sequences showed no significant differences in the analyzed regions, which were not grouped by species or habitat or geographical distribution. Gynandromorph wing markings all fell within the range of variation of normal butterflies; however, a number of genitalic measurements were outliers when compared with normal individuals. Results from this study provide experimental data on mechanisms of food dispersal in monodomous and polydomous colonies of ants, and may be important for increasing the efficacy of management strategies against T. sessile and other pest ant species. Both are invalidated and synonymized with Chetogena Rondani, 1856. We can help you reset your password using the email address linked to your BioOne Complete account. Biparentally inherited and quickly evolving molecular markers like microsatellites are useful for assessing gene flow levels. In addition, anti-HSP70-specific antisera were prepared using a recombinant HSP70 protein, and the results showed that this antisera was very specific to AcHSP70. Mortality rates of young and older larvae varied with conidial concentration of both fungi and elapsed time after application. unguis; 22A 2m X0, M. membranacea), 27 (24A 2m X0, M. brasiliensis and M. uruguayensis), 29 (26A X1X2Y, B. anurum), and 35 (30A X1X2X3X4Y, G. f. flavus).We found that the features of spermatogenesis in these species are similar to those of other previously described Heteroptera species, differing only in testicular morphology, chromosome number, and sex chromosome system. The quantitative real-time reverse transcriptase polymerase chain reaction expression profile for both Sl-pectinases showed mRNA production mainly in the insect feeding stages and exclusively in midgut tissue of the larvae. The predominant pest species of phytophagous stink bugs were the brown stink bug, Euschistus servus (Say), the green stink bug, Chinavia hilaris (Say), and the southern green stink bug, Nezara viridula (L.). CYP9A38 is closest to CYP9A17, CYP9A21, CYP9A20, and CYP9A19 with the highest amino acid identity of 66%. sinensis and R. communis. The sex ratio of the entire population was nearly 50:50, but males dominated in the early half of the duration of the emergence. Additionally, total carbohydrates, lipids, and proteins were quantified from pre and posttissue feeding T. nigriceps larvae to examine the effect of postegression feeding on parasitoid nutritional physiology. From these results, we conclude that the gynandromorphs' genitalia, but not wing patterns, can be abnormal when compared with normal individuals and that the gynandromorphic genitalia do not deviate developmentally in a consistent pattern across individuals. Bactrocera invadens, the Asian fruit fly, was first reported in Kenya in 2003, and it spread fast to most tropical countries in Africa. In polydomous colonies, food dispersal was slower because conspecifics were forced to forage and share food over longer distances. Given the large number of species collected, and the largely unknown relationships existing between the various ecological groups, this study is a first step in the description of the oasis entomofauna. Vuill. The aim of this study was to evaluate the effectiveness of the entomopathogenic fungi (EPF), Beauveria bassiana (Bals.) Numerous microtrichia, as well as trichoid (I, II), basiconic (I), clavate, and coeloconic (I, II) sensillae were observed on the funiculus with a great variation in number and length. Larvicidal bioassays were performed in foam boxes (100 by 75 by 50 cm; length by width by height), containing moist soil medium with some humus and potato tubers as food. It was found that the regions carrying the binding sites for the ecdysone-responsive transcription factor BR-Z2 were responsible for the hormonal enhancement of the reporter gene activity in wing discs. 4×109 conidia/ml) was applied at 100, 150, and 200 ml/100 l water; M. anisopliae strain F52 was applied at 500, 1,000, and 1,500 g/m3 of moist soil medium for GR (9×108 cfu/g) and 75, 100, and 125 ml/100 l water for EC (5.5×109 conidia/ml) formulation. The mitogenome of R. menciana was determined to be 15,301 bp, including 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes, and an AT-rich region. The mortality of D. neivai increased in the first 72 hr in all treatments. Following recent fieldwork in the north of Morocco, we report five new records for the country (Plagiolepis pygmaea Latreille, 1798, Ponera testacea Emery, 1895, Strumigenys tenuipilis Emery, 1915, Temnothorax pardoi Tinaut, 1987, and Tetramorium parvioculum Guillem & Bensusan, 2009) and we present new data on the distribution and natural history of six additional species.
