{"title":"Elevated emissions of oviposition-induced mango volatiles mediate foraging behavior of a parasitoid wasp, Fopius arisanus.","authors":"Bo Wei, Cheng-Mei Wei, Hang Liu, Tian-Yu Bi, Yang Fu, Chun Xiao, Wen-Xia Dong","doi":"10.1002/ps.70617","DOIUrl":"10.1002/ps.70617","url":null,"abstract":"<p><strong>Background: </strong>The parasitoid wasp Fopius arisanus (Hymenoptera: Braconidae) is a solitary egg endoparasitoid of tephritid fruit flies. In this study, we identified the volatile released from the tree-attached mangoes without damage and with oviposition by the oriental fruit fly (Bactrocera dorsalis) in field conditions, and investigated their roles in mediating foraging behavior of this parasitoid species.</p><p><strong>Results: </strong>Ten volatile compounds released by mangoes elicited electrogram responses in antennae or ovipositors of F. arisanus. Among them, α-pinene, d-limonene, β-myrcene, (E)-β-ocimene and ethyl (E)-4-decenoate, individually as well as in a blend attracted female wasps. Likewise, β-myrcene, 3-carene, (E)-β-ocimene, terpinolene and ethyl (E)-4-decenoate, individually, and in a blend attracted male wasps. For female F. arisanus, the blend and ethyl (E)-4-decenoate are primarily detected through their antennae, whereas d-limonene and β-myrcene are mainly perceived via ovipositors. (E)-β-Ocimene appears to be detected by either the antennae or ovipositor, whereas α-pinene is sensed through both organs. Significantly more female individuals landed on the oviposition substrate treated with Blend 3 compared to the paraffin oil control, and the number of wasps exhibiting oviposition behavior was significantly higher in the treatment group during specific time intervals.</p><p><strong>Conclusion: </strong>The oviposition-induced blend of mango volatiles [α-pinene, d-limonene, β-myrcene, (E)-β-ocimene and ethyl (E)-4-decenoate] mediates the foraging behavior of female F. arisanus, and serves as a targeted attractant to enhance its field performance against Tephritidae species. © 2026 Society of Chemical Industry.</p>","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":" ","pages":"5054-5062"},"PeriodicalIF":3.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146130651","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}
