The coevolution of the 'bee-mite-virus' system in Hawaii over 17 years has been closely followed. Resistance to V. destructor evolved in the free-living honey bees on Oahu by detecting and removing a high proportion of mite-infested brood cells, as seen in other mite-resistant honey bees. On Big Island, miticides remain widely used, so on both islands, DWV prevalence decreased, but a more virulent recombinant form evolved. Thus, coevolution on Oahu has produced a new stable 'bee-mite-virus' state that has been exploited by beekeepers and provides a global solution to the V. destructor problem.</p>","PeriodicalId":23327,"journal":{"name":"Trends in parasitology","volume":" ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147843442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
