The maintenance of nitrogen homeostasis in insects is achieved through a balance of dietary intake, metabolic conversion, and excretion. Insects primarily acquire nitrogen from their diet, which is subsequently metabolized into amino acids, proteins, and other vital biomolecules following digestion and absorption. Excess nitrogen is excreted in forms such as uric acid, allantoin, allantoic acid, urea, and ammonia. Disruptions in nitrogen regulation can result in ammonia toxicity and abnormal production or excretion of nitrogenous metabolites, including uric acid, ultimately impairing insect development and survival. This review examines the mechanisms underlying nitrogen homeostasis in insects, with a focus on the intricate regulatory roles of carbohydrate metabolism, amino acid metabolism, uric acid metabolism, urea and polyamine metabolism, ammonia transport pathways, and symbiotic interactions. By elucidating these processes, this review aims to enhance our understanding of insect nutritional metabolism and developmental biology, while offering novel perspectives for the development of more effective pest management strategies.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":"1224-1244"},"PeriodicalIF":3.7,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13441059/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144011141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cytidine triphosphate synthase (CTPS) is a rate-limiting enzyme in nucleotide biosynthesis and assembles filamentous cytoophidia, conserved across species. Despite increasing interest in cytoophidia, how CTPS filaments integrate metabolic and signaling cues to drive cell size and tissue growth remains incompletely understood. Using RNA interference and clustered regularly interspaces short palindromic repeats (CRISPR) / CRISPR-associate nuclease 9 gene editing, we generated CTPS-knockdown and point-mutated mutants to investigate the role of cytoophidia in cell growth. Specifically, we introduced the H355A mutation, which disrupts CTPS filament formation without affecting its enzymatic activity. Our findings revealed that CTPS depletion or filament disruption significantly impairs growth in polyploid organs, such as the fat body and salivary glands, underscoring the pivotal role of CTPS cytoophidia in cell growth regulation. Mutants lacking cytoophidia exhibited reduced DNA replication activity and smaller cell sizes compared to wild-type controls. Mechanistically, we found that nutrient-sensing pathways, particularly insulin-PI3K-Akt signaling pathway, regulate CTPS expression and cytoophidia formation in response to nutrient availability. Activation of the sterol regulatory element-binding protein partially rescued the growth defects caused by CTPS depletion. These findings provide new insights into the molecular mechanisms of the regulation of CTPS filaments, highlighting their role as critical mediators of tissue growth by integrating environmental demands, metabolism, and signaling pathways to regulate cell size and nutrient adaptation.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":"1465-1480"},"PeriodicalIF":3.7,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13440992/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144009657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vitellogenin (Vg) is generally recognized as a female-specific, reproductive lipoprotein unique to oviparous taxa that plays a crucial role in vitellogenesis. However, its specific functions, and the mechanisms underlying its regulation, remain poorly understood. We here demonstrate how 20-hydroxyecdysone (20E) regulates Vg transcription via the transcription factor CsE74A and the ribosomal protein Cs40SRPS4 in Chilo suppressalis. Disruption of CsVg in G0 generation C. suppressalis via multiplex CRISPR/Cas9 resulted in decreased yolk deposition, ovarian dysplasia, and delayed oocyte maturation. Dual luciferase and DNA pull-down assays identified the CsVg core promoter (-915 to -811 bp) and its binding ribosomal protein Cs40SRPS4. Functional analysis via RNA interference revealed that Cs40SRPS4 is a ribosomal protein capable of regulating vitellogenesis in C. suppressalis. Furthermore, we correctly predicted that the binding site for CsE74A would be on the CsVg core promoter and confirmed its binding capability. Subsequent experiments further confirmed the interaction between CsE74A and Cs40SRPS4. Notably, the expression of CsE74A, Cs40S4, and CsVg significantly increased after 20E treatment. The results revealed that 20E induced the early response factor CsE74A to bind to the CsVg core promoter, thereby regulating Vg transcription and vitellogenesis in conjunction with Cs40SRPS4. These findings not only provide a foundation for gaining deeper understanding of insect reproductive processes, but could also lead to the development of safer, more economical and sustainable, pest control methods.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":"1369-1382"},"PeriodicalIF":3.7,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13440981/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144283778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to increasing aphid resistance to insecticides and rising demand for pesticide-free products, pest management is currently based on biological control programs. However, growers often face economic losses because these programs have limited success, largely due to poor establishment of natural enemies when aphid populations are low. This study aimed to evaluate new natural enemies for early-season aphid control. Two candidates were selected to be used against the aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae): the micrococcinellid Scymnus interruptus (Goeze) (Coleoptera: Coccinellidae) and the brown lacewing Micromus variegatus (Fabricius) (Neuroptera: Hemerobiidae). Two studies were conducted to assess their potential as aphid biocontrol agents. Firstly, different alternative food sources that might help for supporting their establishment in the absence of aphids were tested. Secondly, in a greenhouse experiment conducted in walk-in cages, natural enemies were released under preventive conditions (long aphid absence). Their establishment, complementarity, and effectiveness were evaluated during 5 weeks, after periodical low aphid infestations. Our results exposed that supplemental food sources must be provided for the survival of M. variegatus when aphids are absent in the crop. However, S. interruptus could survive in absence of aphids in the presence of sweet pepper flowers for a long period. Our greenhouse trial showed S. interruptus provided better aphid control than M. variegatus but the best results came from combining both species. Overall, our study demonstrated the potential of M. variegatus and S. interruptus as preventive biocontrol agents against aphids in sweet pepper crops.","PeriodicalId":13618,"journal":{"name":"Insect Science","volume":" ","pages":"1663-1674"},"PeriodicalIF":3.7,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13441001/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144553432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we constructed the presence of intraspecific and interspecific competition for pairs breeding on large carcasses, by introducing an additional, small pair of beetles and blowfly maggots Calliphora, respectively. We found that, compared with males and females breeding on large carcasses, males did not change their care, whereas females increased their care when breeding on small carcasses.
