Most LDD takes place on human transport vessels and will typically be rarer and more directionally constrained than active flight but can connect populations and regions that are otherwise mutually inaccessible. These features make LDD worthy of specific consideration in mosquito research. This paper reviews recent evolutionary research on LDD and its consequences for mosquito populations and mosquito control. LDD is the main source of mosquito range expansions, and genomic methods can now trace the origins of new invasions to specific towns or cities. Genomic methods can also give a rough indication of the number of invaders, which if very small may lead to the stochastic loss of advantageous alleles during invasion bottlenecks. Once invasions are established, LDD spreads adaptive alleles between populations. Emerging insights into insecticide resistance evolution indicate that LDD has repeatedly spread resistance mutations across global species ranges, but these broad patterns are convoluted by two other evolutionary processes: parallel adaptation at the same gene or gene cluster and polygenic adaptation at different genes in different populations. Together, these processes have produced patterns of similarity and dissimilarity at resistance genes that are decoupled from geographical distance. LDD within cities is less well studied but is important for planning and evaluating local control efforts. Urban investigations of LDD may help identify areas experiencing weaker selection pressures from insecticides and isolated areas to target for control.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"68 ","pages":"Article 101325"},"PeriodicalIF":5.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142827870","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 genes controlling this process in <em>Drosophila melanogaster</em> were identified in genetic screens and characterized in that species in numerous studies in the 1980s and 1990s. These genes form a well-established hierarchy and have been leveraged to examine gene regulation, transcriptional machinery, chromatin structure, and more. Much of the genetic toolkit identified in <em>Drosophila</em> is highly conserved throughout the animal kingdom, spearheading the field of evolutionary developmental biology or Evo-Devo. Accordingly, a ‘<em>Drosophila</em>-centric’ approach has examined the evolutionary conservation of orthologs of <em>Drosophila</em> segmentation genes in closely and distantly related insects. Here, we report on progress in both <em>Drosophila</em> and emerging model insects in recent years (2022 to present), with much of the new research related to the pair-rule subset of segmentation genes. We highlight new findings on ‘classic’ <em>Drosophila</em> genes, revealing unexpected roles of genes and cis-regulatory elements in this species. We further report on the expanding knowledge about mechanisms regulating to segmentation in emerging model insects that are distantly related to <em>Drosophila</em>, including those that pattern segments sequentially.

Given their large spatial extent, the impacts of megafire on biodiversity and ecosystem functioning could differ substantially from the impacts of typically sized fires, even in fire-adapted ecosystems. In this review, we investigate the potential impacts of megafires on pollination systems. The extensive spatial extent of megafires can lead to large amounts of habitat being exposed to high-severity fires, which may increase insect mortality, especially for taxa that cannot take refuge in underground nests or other refuges. In the most extreme cases, megafires may result in the local — or global — extinction of plant and pollinator species, which, in turn, can trigger co-extinctions and lessen the resilience of pollination networks. In addition, smoke can exacerbate initial mortality by interfering with insect sensory systems, decreasing foraging behaviours, and negatively impacting insect health and immunity. Worryingly, smoke can impact pollination systems thousands of kilometres away from the fire. The negative effects of megafires may be exacerbated by inter-connected nonlinear feedback loops such as extinction cascades, colony collapse and Allee effects, which may make the response of pollination systems to fires harder to predict. Since megafires will almost certainly become a feature of our future, understanding how interconnected stressors will impact pollinators and pollination systems is key to safeguarding global pollination systems.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"68 ","pages":"Article 101304"},"PeriodicalIF":5.8,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142709565","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}
