Honey bees are perfectly suitable to study time memory mechanisms: they possess an elaborated time memory combined with a relatively simple neuronal clock network and a smaller gene set compared with the mouse model organism. This review provides a short overview majorly across insects, which have demonstrated time memory capabilities, with a focus on time-place learning, and describes basic properties as well as state-of-the-art research connecting time memory with the circadian clock at the behavioral, molecular and neuroanatomical level. Despite a long history of research on time memory of honey bees, putative connections between clock and time memory have only recently been identified and imply a rather complex regulation mechanism with multiple signaling pathways.</p>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"101327"},"PeriodicalIF":5.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142827875","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}

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.</p>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we lay out a framework of open questions (see graphical abstract) that can be addressed separately in each system and, ultimately, compared across systems to seek general patterns in supergene evolution. Few empirical studies have investigated what causes new supergene haplotypes to initially increase in frequency, but to not eventually fix in a population.

This implies that they may respond to other sensory cues, such as slight temperature changes, vibrations, and/or odors, to trigger biting attempts. Besides, new studies reveal that triatomines can ingest plant or fruit fluids, showing a broader dietary flexibility than previously recognized. Future research should focus on how triatomines detect and respond to sensory cues from poikilothermic hosts or plant fluids, and how these sensory inputs influence their feeding behavior. Understanding their sensory abilities and dietary flexibility could have important implications for vector surveillance and control, offering insights into the evolutionary shift from predatory to blood-feeding behaviors.</p>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"68 ","pages":"101301"},"PeriodicalIF":5.8,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142791258","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}

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 Drosophila is highly conserved throughout the animal kingdom, spearheading the field of evolutionary developmental biology or Evo-Devo. Accordingly, a 'Drosophila-centric' approach has examined the evolutionary conservation of orthologs of Drosophila segmentation genes in closely and distantly related insects. Here, we report on progress in both Drosophila 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' Drosophila genes, revealing unexpected roles of genes and cis-regulatory elements in this species.

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.</p>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":" ","pages":"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}
