In this opinion article, I propose Ratchet-Driven Generalism (RDG): in some parasites, broad host range may instead arise non-adaptively after the loss of sexual recombination. Under Muller's ratchet, deleterious mutations accumulate in asexual or rarely recombining lineages. Over time, genomic erosion can degrade host-specific adaptations, including host-interaction genes. In parallel, reduced competitive filtering among parasite genotypes can weaken selection for host-specific performance. Consequently, genotypes that are merely viable across hosts may persist. RDG predicts genomic signatures of functional decay and reduced efficacy of selection. It also suggests that such generalism may be transient, because continued genomic erosion can increase extinction risk. I outline comparative genomic tests to examine RDG.</p>","PeriodicalId":23327,"journal":{"name":"Trends in parasitology","volume":" ","pages":"705-715"},"PeriodicalIF":7.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148340396","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}

Western honeybees have experienced high colony losses globally, mainly driven by the host-shifted, virus-vectoring ectoparasitic mites Varroa destructor and Tropilaelaps mercedesae. Host populations can survive mite infestations through natural selection, offering a long-term strategy for colony health. However, host-vector-virus coevolution requires local adaptations of this triad, which is poorly understood. We propose harnessing natural selection through a global approach focused on standardized monitoring of colony survival, mite infestation levels, and control of reproductives. Studying native and adapted mite hosts, host shifts, and comparing susceptible to surviving hosts will enhance understanding of this host-vector-virus system. This strategy promotes colony health in both managed and wild host populations and provides insights into other host-vector-virus interfaces.</p>","PeriodicalId":23327,"journal":{"name":"Trends in parasitology","volume":" ","pages":"716-728"},"PeriodicalIF":7.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148253270","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}

In this review, we examine how arthropod-derived molecules disrupt epithelial barrier integrity, activate innate immune pathways, and promote type 2 immune polarization and IgE-mediated sensitization, exemplified by alpha-gal syndrome. We further integrate the epithelial barrier hypothesis with advances in component-resolved diagnostics, AI-assisted precision medicine, and One Health surveillance approaches to provide a systems-level perspective on arthropod allergy.
