Understanding <em>Aedes aegypti</em>’<em>s</em> mating behaviour and pheromones is crucial for expanding knowledge and advancing vector control strategies. Unlike other species, <em>Aedes</em> mosquitoes have adaptable mating behaviour, complicating the study of their communication mechanisms. Current literature on <em>Aedes</em> communication is sparse, not due to lack of effort but because of its complexity. <em>Ae. aegypti</em>’<em>s</em> mating behaviour is influenced by sensory cues and environmental factors. Swarming, which facilitates mating aggregation, is triggered by host odours, highlighting the role of semiochemicals alongside aggregation pheromones. Cuticular hydrocarbons may act as chemical signals in mating, though their roles are unclear. Acoustic signals significantly contribute to mate attraction and male fitness assessment, showcasing the multidimensional nature of <em>Ae. aegypti</em> sexual communication. Understanding these aspects can enhance targeted control strategies and reduce mosquito populations and disease transmission.</p></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"65 ","pages":"Article 101237"},"PeriodicalIF":5.8,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214574524000798/pdfft?md5=79ccad2f4bb35d14c8b3e4fa80c26b08&pid=1-s2.0-S2214574524000798-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141757700","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}

The sesquiterpenoid hormones and their synthetic mimics are agonist ligands of a unique JH receptor (JHR) protein, methoprene-tolerant (MET). Upon binding an agonist to its PAS-B cavity, MET dissociates from a cytoplasmic chaperone complex including HSP83 and concomitantly switches to a bHLH-PAS partner taiman, forming a nuclear, transcriptionally active JHR heterodimer. This course of events resembles the vertebrate aryl hydrocarbon receptor (AHR), activated by a plethora of endogenous and synthetic compounds. Like in AHR, the pliable PAS-B cavity of MET adjusts to diverse ligands and binds them through similar mechanisms. Despite recent progress, we only begin to discern agonist-induced conformational shifts within the PAS-B domain, with the ultimate goal of understanding how these localized changes stimulate the assembly of the active JHR complex and, thus, fully grasp the mechanism of JHR signaling.</p></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"65 ","pages":"Article 101234"},"PeriodicalIF":5.8,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214574524000762/pdfft?md5=e947b21312d9e8992bac1a9dbad34e0d&pid=1-s2.0-S2214574524000762-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141723279","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}

Here, we briefly review three scientific advancements that, when integrated, can be highly synergistic for advancing our knowledge of the genetics and evolution of eusocial traits. Population genomics provides a natural way to quantify the strength of natural selection on coding and regulatory sequences, highlighting genes that have undergone adaptive evolution during the evolution or maintenance of eusociality. Genome-wide association studies (GWAS) can be used to characterize the complex genetic architecture underlying eusocial traits and identify candidate causal variants. Concurrently, CRISPR/Cas9 enables the precise manipulation of gene function to both validate genotype–phenotype associations and study the molecular biology underlying interesting traits. While each approach has its own advantages and disadvantages, which we discuss herein, we argue that their combination will ultimately help us better understand the genetics and evolution of eusocial behavior. Specifically, by triangulating across these three different approaches, researchers can directly identify and study loci that have a causal association with key phenotypes and have evidence of positive selection over the relevant timescales associated with the evolution and maintenance of eusociality in insects.</p></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"65 ","pages":"Article 101231"},"PeriodicalIF":5.8,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214574524000737/pdfft?md5=def5feae1854413d419a230e3ae428cb&pid=1-s2.0-S2214574524000737-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141558338","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}
