Sex determining mechanisms have been extensively analyzed using the genetic model insects, such as <em>Drosophila melanogaster</em>, revealing that insect sex is determined in a cell-autonomous manner. The sexual identity of each cell is governed by the conserved transcription factor Doublesex, while the regulatory mechanisms controlling its expression are species specific. In contrast, our understanding of how environmental factors modulate the sex determination pathway remains limited. In this review, we summarize recent discoveries on the crosstalk between environmental factors and sex determination pathways in the lepidopteran insects and the cladoceran crustaceans, which are closely related to insects. We discuss how the symbiotic bacterium <em>Wolbachia</em> hijacks the host WZ/ZZ sex determination pathway in the lepidopteran <em>Ostrinia furnacalis</em>. In addition, we highlight how males that are genetically identical to females are produced in response to environmental stimuli in the cladoceran crustacean <em>Daphnia magna</em>. Based on these findings, we explore the evolutionary, ecological, and applied implications of the molecular mechanisms underlying environmentally influenced sex determination.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"71 ","pages":"Article 101403"},"PeriodicalIF":5.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aggressive behavior is also highly plastic, with animals quickly adjusting their aggression level in response to environmental and social context. Neuroendocrine systems govern this regulation. While the neuroendocrine mechanisms of aggression have been extensively studied in vertebrates, they remain underexplored in insects. Recent advances in analytical techniques have provided new opportunities to investigate these mechanisms with greater precision. This research is particularly timely as insects face an increasing number of environmental stressors, including anthropogenic factors, which disrupt their neuroendocrine systems. This review aims to highlight the roles of hormones (juvenile hormone, ecdysteroids) and biogenic amines (dopamine, tyramine, octopamine, serotonin) in regulating insect aggression, emphasizing recent advances. We further discuss how environmental stressors impact neuroendocrine pathways and the resulting implications for aggression, population stability, and ecosystem services.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"71 ","pages":"Article 101407"},"PeriodicalIF":5.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we explore how insect herbivores might exploit plant secondary metabolites to enhance immune function. We propose that herbivores experience a ‘window of enhanced immunity,’ where toxins confer immune benefits at low concentrations, but suppress immune responses at higher concentrations. This concept bridges the interplay between bottom-up (plant defense) and top-down (natural enemy) pressures, providing insights into how herbivores balance challenges posed by exposure to plant toxins and exposure to their natural enemies. We discuss how both generalist and specialist herbivores navigate this balance, highlighting the evolutionary adaptations that influence their strategies. We suggest that the immune systems of specialist and generalist herbivores may both exhibit hormetic responses to plant toxins, although the shape of this relationship likely differs depending on their ability to detoxify and sequester plant toxins.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"71 ","pages":"Article 101405"},"PeriodicalIF":5.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144511663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
