Levels of activity of selected enzymes also were measured. Varying levels of resistance to afidopyropen were detected among aphids from nine major cotton-growing areas in the region. Higher resistance levels were detected in aphids collected from Tumshuk, Alar, and Kurle, with resistance ratios of 4.570, 2.058, and 1.565, respectively. Lower resistance ratios of 0.506, 0.632, and 0.775 were detected in aphids collected from Yinli, Wujiaqu, and Hami, respectively. Biochemical assays showed a highly significant positive correlation of the detoxifying enzymes carboxylesterase and multifunctional oxidase with the level of tolerance, with enzyme activity increasing with the level of tolerance. Glutathione S-transferases and acetylcholinesterase activity in field-collected aphids differed significantly from laboratory colony populations, but their activity did not differ among the field populations. We concluded that cotton aphids in major cotton areas of Xinjiang have not yet developed resistance to afidopyropen and remain sensitive to afidopyropen as indicated by resistance ratios of <5; however, resistance of cotton aphids to afidopyropen in southern Xinjiang is higher than that detected in cotton aphid populations in northern Xinjiang.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44610010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Hymenoptera: Siricidae) in Louisiana to identify host-associated olfactory stimulants that may include attractive semiochemicals for this species as well as Sirex noctilio F., an invasive species that can attack healthy trees. Loblolly pines (Pinus taeda L.) treated with a stressing agent were felled and chipped 1–2 mo after treatment, and the chips were steam–water distilled in a Clevenger apparatus to extract volatile compounds. Using coupled gas chromatography–electroantennographic detection, we analyzed the distillates with antennae of both S. nigricornis and the Sirex parasitoid Ibalia leucospoides (Hochenwarth) (Hymenoptera: Ibaliidae) to identify olfactory stimulants. In addition, we assayed S. nigricornis antennae with synthetic mixtures containing 23 volatile compounds associated with stressed and dying pines, including pheromones of bark beetles (Coleoptera: Curculionidae: Scolytinae) that also use these hosts. Antennae of both male and female S. nigricornis responded to 29 identifiable volatiles in the distillates, whereas I. leucospoides responded to 23 volatiles. Eighteen compounds in the synthetic mixtures were olfactory stimulants for S. nigricornis. Olfactory stimulants in the woodchip distillates were predominantly hydrocarbon and oxygenated monoterpenes, and the strongest antennal stimulants among compounds in the synthetic mixtures were oxygenated monoterpenes associated with pine death and early decay (e.g., verbenone, fenchone, and terpinen-4-ol). Bark beetle pheromones (frontalin, endo-brevicomin, ipsenol, and ipsdienol) also stimulated S. nigricornis antennae. The very large number of host-associated olfactory stimulants for S. nigricornis implies that our data may offer limited assistance in targeting individual compounds for investigation as possible attractants and components for a Sirex lure.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46927024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Essential oils from plants that show insecticidal activity can be substituted for synthetic insecticides to reduce environmental pollution or harmful toxicity to humans. Insecticidal activity of essential oil from seeds of coriander, Foeniculum vulgare Miller (Apiales: Apiaceae), on maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), and its effects on seed germination of three major economic crops were investigated. Essential oil from F. vulgare seeds was analyzed by gas chromatography–mass spectrometry and found to contain 25 components, with anethole (43.78%) as the main constituent. Other basic compounds were estragole (28.33%), fenchone (16.68%), d-limonene (2.62%), alpha-pinene (1.84%), and p-cymene (1.28%). Foeniculum vulgare essential oil was toxic to maize weevil when used as a fumigant with a median lethal concentration at 48 h of 10.42 µL/L air. A concentration of 64 µL/L air was most effective, killing 100% of maize weevil within 24 h. The repellent effect on maize weevil increased to 75% at 24 h at a concentration of 16 µL/L air. Rice (Oryza sativa L.) and sorghum (Sorghum bicolor [L.] Moench) seeds fumigated with 32 µL/L air of F. vulgare essential oil exhibited a slight decrease in germination rate (germination >90%). Our results indicate that essential oil from F. vulgare seeds have potential for application in the management of maize weevil in stored products.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44025478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over all concentrations tested, bacterial species associated with N. lugens comprised 8 phyla, 17 classes, 22 orders, 26 families, and 31 genera of which the relative proportions of Arsenophonus, Burkholderia, Enterobacter, Pseudomonas, Stenotrophomonas, and Bacteroides were highest. The relative abundance and diversity of bacteria were highest in the carrier control (0.05% Tween-80 only). Fungi comprised 1 phyla, 5 classes, 10 orders, 13 families, and 18 genera, with Metarhizium being the dominant taxon in specimens from all treatment groups. Metarhizium spp. was greatest in the concentrations of 107 and 108 conidia/ml at 72 hours after exposure, reaching 94.82% and 93.74% of taxonomic units, respectively. We deduced that M. flavoviride competes for nutrition with midgut microorganisms; therefore, exposure to a pathogenic fungus will change the abundance and diversity of bacterial and fungal microorganisms in the midguts of hosts, and pathogens will impact the structure of bacterial communities in the host midgut with an alteration in the bacterial species composition. We observed that following the exposure of N. lugens to M. flavoviride, Metarhizium spp. dominated in the midgut of the host, the abundance and diversity of midgut fungal microorganisms decreased, and the dominant bacterial species in the midgut shifted.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43157441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under these conditions, peak emergence of female adults occurred in the sixth day after pupation, and peak emergence of males was in the seventh day after pupation. Emergence for both sexes occurred throughout the day. Courtship behavior began at the sixth hour of scotophase, reaching peak activity between the 10th hour of scotophase and the first hour of photophase. The courtship and mating success rate were highest for 1-d-old females, and then gradually decreased with age until no mating was observed after females were 4 d old. With 1-d-old females, mating was only observed from the seventh hour of scotophase to the first hour of photophase, with peak activity at 0.5 h after the onset of photophase. Oviposition primarily occurred within 3 d after mating, with 49.8% of the eggs being deposited during the first day after mating.

In most lepidopteran species, challenging the immune system causes an increase in hemocyte numbers and promotes encapsulation and melanization of invading objects, such as parasitoid eggs or artificial objects (e.g., nylon implants). We studied the effects of carbon particles (Sumi ink) on the immune response of Galleria mellonella L. (Lepidoptera: Pyralidae) last-instar larvae. Ink injections increased total hemocyte counts in a dose-dependent manner, with the 40 and 80% concentrations being most effective in eliciting hemocyte response. Hemocyte numbers increased significantly at 4 and 6 h after ink injection. Lemongrass essential oil (0.18, 0.36, and 0.72 µg/larva) and citral (0.12, 0.24, and 0.48 µg/larva) reversed the mobilization of hemocytes by the ink. Melanization of nylon larvae implants started as early as 15 min after implant insertion and reached maximum observed levels within 1 h. The degree of melanization also was higher in larvae challenged with ink 1 h prior to implant removal, which suggests initialization of the immune response. Citral injections inhibited implant melanization both in unchallenged and ink-challenged larvae. In the former case, citral concentrations needed for effective inhibition were less (0.3 µg/larva) than in ink-challenged larvae (1.2 and 2.4 µg/larva).","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42922490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
