It is well reviewed that chemical signals play key roles in interactions between conspecific insects, such as sex pheromones for finding mates, and that plants transmit chemical signals to recruit natural enemies that kill herbivores. However, it is also known that chemicals emitted by natural enemies can influence insect herbivore physiology and behavior. The detection of chemical cues associated with the presence of natural enemies can influence herbivore movement, feeding, and reproduction, which may limit the damage herbivores inflict on their host plants. Plants detect chemical cues associated with herbivores, but less is known about whether plants also detect chemical cues of natural enemies or how this detection affects plant defense responses. In this review, we highlight what is known about how natural enemy chemical cues directly affect herbivores, how natural enemy cues indirectly affect herbivores through changes in host plant defenses, and we discuss the evolutionary ecology of plant and herbivore responses to natural enemy cues. Finally, we consider application of these concepts for insect pest management. Improving our understanding of how natural enemy chemical cues mediate multitrophic interactions provides a great opportunity for future exploration.</div></div><div><h3>Condensed Abstract</h3><div>Plants and invertebrates use chemical signals and cues to construct information about their environment.

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 levels.

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}

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.
