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":"58 1","pages":"104 - 116"},"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}

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":"57 1","pages":"587 - 602"},"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}

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":"57 1","pages":"573 - 586"},"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}

To establish a baseline of information for possible ecological management of this pest, we studied its emergence, courtship, mating, and oviposition behaviors in the laboratory at 27 ± 1°C and 60 ± 10% relative humidity under a 14:10-h (light:dark) photoperiod. 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. These results demonstrate that there are distinct circadian rhythms in adult emergence and subsequent reproductive behavior of C. anastomosis, thus providing a basis for development of monitoring and management strategies of this pest.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"57 1","pages":"447 - 459"},"PeriodicalIF":0.9,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47659570","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}

Since the first detection in Minnesota in 2012, D. suzukii rapidly became a major economic pest of berry crops in the state. Effective monitoring of adult D. suzukii populations is a crucial aspect of developing integrated pest management (IPM) programs for at-risk crops. Drosophila suzukii monitoring research was conducted in 2016 and 2017 to better understand the effectiveness of two commercially available trapping systems for early detection of adults in spring and how mean trap catches compared over time. In addition, using the Scentry trap, we assessed the impact of lure age on trap performance. Finally, a study was conducted to better understand the diurnal activity pattern for adult D. suzukii under Minnesota summer conditions. Results comparing the trapping systems indicated each system varied in its ability to detect first catch of D. suzukii but that both commercial traps/lures were effective. The lure age study showed that lures can be changed less frequently than initially suggested. Temporal activity studies, as measured by trap catch via Scentry traps, indicated that adult D. suzukii demonstrated a crepuscular activity pattern in raspberry and blueberry. The results of these studies should benefit growers as they continue to fine-tune fruit IPM programs for D. suzukii.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"57 1","pages":"516 - 529"},"PeriodicalIF":0.9,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45975102","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}

We found that aphids feeding on inverted or horizontally perpendicular positioned leaf discs exhibited higher survival and fecundity rates than those aphids feeding on upright positioned leaf discs for all three populations. Overall, aphids in both the Gansu red and Gansu green populations performed best when feeding on the inverted leaf discs, whereas aphids of the Yunnan green population performed best in the horizontally perpendicular orientation.

Our transcriptome analysis of the interaction between Hong Yang kiwifruit and B. dorsalis revealed numerous changes in gene expression level attributable to Oriental fruit fly feeding, resulting in the down-regulation of 112 genes and the up-regulation of 226 genes. Gene ontology analysis revealed that differential expression genes (DEGs) were mainly involved in biological processes (4,568; 56.28%), molecular function (2,297; 28.30%), and cellular components (1,251; 15.41%). By searching against the Kyoto Encyclopedia of Genes and Genomes Pathway database (KEGG), 258 DEGs were assigned to 51 KEGG pathways belonging to five main categories: metabolism (239, 92.64%), genetic information processing (10, 3.88%), organismal systems (5, 1.94%), cellular processes (3, 1.16%), and environmental information processing (1, 0.39%). The numbers of DEGs up-regulated were much higher than those down-regulated. Expression of genes involved in the secondary metabolism was detected, and several key genes showed differential expression. Our results suggest that B. dorsalis induced defense response of Hong Yang kiwifruit, including hypersensitive response and immunity triggered by either pathogen/microbe-associated molecular patterns or immunity effectors.
