Afidopyropen is a novel biogenic pesticide widely applied to control sap-feeding pests, and a few studies have evaluated the side effects of afidopyropen on pollinators, excluding the Asian honeybee. Thus, we estimated the physiological influences of afidopyropen in Apis cerana, which could cause significant death and nutritional deficiency in bees after continuous dietary intake (14 days) at the field recommended dose. Moreover, we found afidopyropen ingestion-induced changes in the activity of detoxification enzymes (AChE, GR, CarE) and expression of genes critical for the central nervous system and chemosensory function in the antennae, brain, midgut, and malpighian tubule of exposed bees. However, there was no evidence that there was a long-term impact on foraging activity when observing foragers treated with apfidopyropen as newly emerged workers. Overall, our study provides vital information to improve bee health, which will improve outcomes for beekeepers, increase pollination services, and strengthen pollinator communities.
