While management of this pest relies heavily on chemical insecticides, the evolution of resistance and environmental concerns underscore the need for new and more effective approaches. Genetic-based strategies that target male fertiliy are currently being evaluated for population suppression. However, a lack of candidate gene targets with appropriate function, specifically in non-model species like L. hesperus, has hindered progress in the development and application of such approaches. Given their conserved role in stabilization of the flagella axoneme and association with sperm motility in many organisms, members of the tektin gene family represent logical targets for genetic-based sterilization. Here, we identified four homologs of the non-vertebrate tektin family from L. hesperus and used RNA interference-mediated knockdown to assess their roles in male fertility. Although transcription of the four tektins was predominantly in the testis, knockdown had negligible effects on either sperm abundance or male fertility. Our results suggest that tektins do not play a critical role in sperm fertilization of eggs in L. hesperus and are thus likely poor targets for genetic-based sterilization approaches in this species.</div>","PeriodicalId":8281,"journal":{"name":"Archives of Insect Biochemistry and Physiology","volume":"118 4","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749735","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}

Phylogenetically, beetles belong to the order Coleoptera, the most species-rich of the Insecta. Coleoptera is divided into four suborders: Polyphaga, Adephaga, Archostemata, and Myxophaga. Specimens from the latter two are difficult to obtain, hence, we have focused our research into the adipokinetic hormone (AKH) peptide family on the former two suborders. Data on the Adephaga were concluded in 2017. The “core Polyphaga” consists of three series: Elateriformia, Staphyliniformia, and Cucujiformia; the latter was concluded in 2019. Here, we report on the AKH sequence(s) of 23 species of beetles from 4 families of Elateriformia, namely, the Buprestidae, Cantharidae, Elateridae, and Lampyridae; and 4 families of Staphyliniformia, namely, the Hydrophilidae, Silphidae, Lucanidae, and Scarabaeidae. Sequence elucidation by mass spectrometry or Edman degradation revealed 13 octapeptides: 5 are novel, 12 are beetle-specific and Schgr-AKH-II is produced in the basal Polyphaga (Elateriformia, in Hydrophilididae and Silphidae). Since Schgr-AKH-II is also found in Adephaga, this confirms the ancestral AKH of Coleoptera. The first change in sequence is recorded in Staphylinoidea with two different residues, notably, the switch from Phe4 to Tyr4. Duplication of AKH peptides is first seen in Lucanidae, as well as the appearance of atypical AKH sequences, such as Phe2, Met4, Leu4, or Phe7 encountered in the Scarabaeoidea. The vast majority of the pest beetles do not have beetle-specific AKHs or share the same AKH as nonharmful beetles. Ideas for finding a lead compound for green insecticides are discussed.","PeriodicalId":8281,"journal":{"name":"Archives of Insect Biochemistry and Physiology","volume":"118 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11926582/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we demonstrated the existence of TGIP in silkworms by exposing the parental generation to a low dose of Bombyx mori nucleopolyhedrovirus (BmNPV). Notably, when maternal or paternal-primed moths were mated to produce the F1 generation, the F1 generation larvae from both primed groups were more resistant to the BmNPV challenge than silkworm larvae with only maternal or paternal priming. Importantly, both maternal and paternal contributions to offspring immunity were essential for TGIP. However, due to the characteristics of the BmNPV itself, no within-generation immune responses were detected following BmNPV priming. Further analysis revealed that immune-related genes might play a role in mediating specific TGIP in silkworms after BmNPV priming.

Humidity was believed to control green/brown color polyphenism in locust species. However, recent findings indicate that humidity has minimal influence on this polyphenism in Schistocerca gregaria nymphs reared in isolation. This study investigated the effects of humidity and visual stimuli on Locusta migratoria nymphs reared in isolation. When L. migratoria nymphs were fed either Bromus catharticus or Dactylis glomerata leaves only during the dark period, the proportions of green nymphs at the 5th instar were comparable. Increased humidity (through addition of moist cotton) induced more green morphs under a 16-h dark/8-h light cycle, suggesting that humidity is involved in green/brown polyphenism in L. migratoria. However, these nymphs were not sensitive to humidity regarding this polyphenism under a 23-h dark/1-h light cycle, suggesting that sensitivity is related to visual cues. The daily overlap between food availability and light periods for 12 h resulted in a higher proportion of green morphs than a daily overlap for only 4 h, suggesting that such an overlap affects green/brown polyphenism in this species. Although we were unable to assess the effect of the total food availability period on polyphenism in this study, we confirmed that at least (1) humidity and (2) visual cues during feeding are associated with green/brown polyphenism in L. migratoria. These regulations may have ecological significance for this species, allowing them to phenotypically adjust to the seasonal and spatial variation in their environment, increasing their chances of survival.","PeriodicalId":8281,"journal":{"name":"Archives of Insect Biochemistry and Physiology","volume":"118 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/arch.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
