摘要: Honey bees are frequently exposed to multiple stressors in natural habitats, such as pesticides and parasites, which may potentially interact and lead to synergistic effects. Tropilaelaps mercedesae is an ectoparasitic mite that severely affects Apis mellifera, feeding on hemolymph and fat bodies of honey bee larvae and pupae, and carrying honey bee viruses. Chlorantraniliprole, a diamide insecticide widely used in agricultural production, poses potential long-term risks to bee health. In this study, we investigated the combined impacts of T. mercedesae and chlorantraniliprole on Apis mellifera. Co-exposure to T. mercedesae and chlorantraniliprole resulted in a synergistic effect, significantly reducing the survival of honey bees, while increasing the activities of oxidative stress-related enzymes, including catalase, peroxidase, and superoxide dismutase. In addition, the expression levels of abaecin and defensin 1 were suppressed, whereas vitellogenin was significantly upregulated. These findings deepen our understanding of how biotic and abiotic stressors interact to affect honey bees and provide valuable insights for developing more effective strategies for their conservation.
