摘要: Chlorantraniliprole (CAP), a diamide insecticide, is extensively applied to combat pests in various crops. However, the widespread use of insecticides has raised concerns about their potential impact on pollinators. In the present study, we explored the toxic effects of CAP in two important honey bee species, Apis mellifera and Apis cerana. The 48 h LC50 values of CAP for A. mellifera and A. cerana was 256.052 mg/L and 109.709 mg/L, implying that A. cerana is more sensitive to CAP. Prolonged exposure to 40 mg/L CAP significantly impaired sucrose responsiveness and climbing activity in both bee species. Both species showed a decrease in GR activity and GSH content with increasing CAP concentration. By contrast, the activities of GST, CAT, P450 and NAD-MDH were increased in both A. mellifera and A. cerana, but the differences between the 10 mg/L and 40 mg/L treatments were less pronounced in A. mellifera. Moreover, the immune related genes exhibited differential responses to CAP when comparing the two species. Low CAP concentrations led to down-regulation in expression of toll but up-regulation in expression of apideacin and hymeopatecin in A. mellifera, whereas A. cerana exhibited minimal changes in these genes. Additionally, CAP significantly inhibited the expression of ER stress response genes gp-93 and P58 in A. mellifera, while 10 mg/L of CAP promoted P58 expression in A. cerana. Our results highlight species-specific effects with the possible, distinct detoxification mechanisms and immune responses between A. mellifera and A. cerana. These findings serve as a foundation for further evaluating the safety of CAP for honey bee species and offer insights into the scientific use of pesticides.
