While essential metals have well-characterized metal-specific transporters, nonessential metals either require general xenobiotic transporters or interact with established essential metal-specific pathways. This review highlights recent advancements in identifying anthropogenic sources of contamination, insect responses to metal contamination, and the underlying response and transport pathways. We emphasize the importance of considering diversity within and between species, beyond classical models, to better understand biological responses.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"75 ","pages":"Article 101488"},"PeriodicalIF":4.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146003076","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}

Genetically modified mosquitoes (GMMs) offer a promising, innovative approach to reducing malaria transmission. However, the foundational research to identify the target gene candidates for genetic modification is typically conducted under static laboratory conditions. These standardized insectary settings of constant temperature and humidity do not reflect the dynamic environmental and climatic variability that mosquitoes and the pathogens they carry encounter in nature. Here we argue that this ‘lab-to-field’ discrepancy represents a significant knowledge gap. We highlight that natural variations in environmental factors influence <em>Anopheles</em> and <em>Plasmodium</em> biology, and mosquito innate immunity responses, with consequences for vector competence and malaria transmission. Insufficient consideration of environmental variability during the initial gene discovery phase risks developing GMMs where the intended function of the genetic modification may be compromised by environmental stress. We emphasize the need to incorporate realistic environmental variability into the upstream GMM development, particularly in the face of escalating climate change.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"75 ","pages":"Article 101489"},"PeriodicalIF":4.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146003097","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}

Unfertilized eggs develop into haploid males, and fertilized eggs develop into diploid females. Many species further have complementary sex determination (CSD), a mechanism by which hemizygosity results in normal male development, and heterozygosity results in normal female development. However, homozygosity (at one or multiple CSD loci) results in aberrant diploid males that are frequently reproductively challenged and threaten population health. CSD is broadly distributed taxonomically, but only the honey bee <em>csd</em> and a few candidate genomic regions in a few other species are known. Honey bee <em>csd</em> has been a flagship model for 20 years. Recent studies expand on mechanisms at multiple levels that maximize CSD diversity and functional heterozygosity, from molecular aspects to population dynamics. This demonstrates that a similar depth of knowledge for other CSD species is achievable, but there are technical limitations to discovering CSD loci and interpreting downstream population impacts. These include a lack of diploid males needed for loci identification (particularly for ml-CSD systems) and challenges to functional validation. Here, we suggest practical solutions. This review summarizes recent discoveries of CSD properties in the honey bee and new candidates in several species of bees, parasitoid wasps, and ants. Notably, there is both evidence of independent de-novo evolution (e.g. honey bees) and deep-level conservation (i.e. ants, mason bee, bumble bee) of CSD mechanisms. We then highlight ways to develop an integrative framework for understanding the implications of CSD knowledge for control of invasive populations and conservation of endangered populations.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"74 ","pages":"Article 101480"},"PeriodicalIF":4.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145843556","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}
