It focuses on successful classical, conservative, and augmentative techniques that form the foundation for implementing effective and sustainable biological control strategies involving parasitoids in India.

Understanding the major mechanisms underlying diversification in parasitoids should be a high priority, not the least in order to predict consequences from high extinction rates currently observed. The two major hypotheses explaining host-associated diversification are the escape-and-radiate hypothesis and the oscillation hypothesis, where the former assumes that key innovations are major drivers of radiation bursts, whereas the latter rather assumes that diversification depends on processes acting on the standing genetic variation that influences host use. This paper reviews the recent literature on parasitoid speciation in light of these major hypotheses to identify potential key innovations and host use variability underlying diversification. The paper also calls upon recent theoretical advances from a similar system, plant–butterfly interactions, to provide shortcuts in the development of theories explaining the high diversity of parasitoid wasps.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"66 ","pages":"Article 101281"},"PeriodicalIF":5.8,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142399700","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}

A growing amount of attention has been paid to the ethical challenges associated with lethal insect monitoring to include unclear environmental risks, welfare harms to insects, concerns about taking life, and more. Accordingly, we survey the literature raising questions about best practices in lethal monitoring, which, while largely focused on pollinators, applies more broadly to any insect monitoring initiatives. We consider whether monitoring is always required, whether monitoring must always be lethal, and whether lethal monitoring needs to kill as many individuals as standard methods do. We end by advocating for additional ethical dialogue that can assist practitioners in negotiating the variety of moral values that bear on these issues.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"66 ","pages":"Article 101279"},"PeriodicalIF":5.8,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142380177","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}
