Abstract

This article investigates the effects of sublethal oral exposure to the acaricide cyflumetofen on key organs of the honey bee, Apis mellifera, a globally important pollinator. Workers exposed to 5 ppm of a cyflumetofen formulation for 72 hours showed significant midgut damage characterized by cytoplasmic vacuolation and cell fragmentation, while after 10 days, midgut recovery was observed. The hypopharyngeal glands exhibited altered secretory activity with accumulated secretions after both exposure periods, potentially affecting gland function and colony health. No histopathological or ultrastructural changes were detected in the fat body. These findings suggest that even low residual concentrations of cyflumetofen can impair honey bee organ function, which may compromise individual fitness and colony maintenance.
