To identify an environmentally friendly and efficient method for controlling Chinese bean weeril Callosobruchus chinensis, a sealed fumigation method was used to evaluate the fumigation effects of four plant volatiles (trans-anethole, citral, 4-allylanisole, and eugenol) on adult C. chinensis. The plant volatile with the best fumigation effect was selected and combined with diatomaceous earth to determine its laboratory toxicity, control efficacy, and effects on multiple enzyme activities in C. chinensis. The results showed that among the four plant volatiles, trans-anethole exhibited the strongest fumigation effect. At a concentration of 5 μL/L, trans-anethole achieved a corrected mortality rate of 100.00% against for adult C. chinensis after 48 hours of treatment. The combination of trans-anethole and diatomaceous earth demonstrated a significant synergistic effect, with an LC50 of 3.040 μL/L against adult C. chinensis, compared to 6.979 μL/L for trans-anethole alone. Diatomaceous earth alone had no effect on the activities of catalase, acetylcholinesterase, succinate dehydrogenase, peroxidase, glutathione-S-transferase, and superoxide dismutase in C. chinensis. These findings indicate that the combination of trans-anethole and diatomaceous earth can be used for the green control of C. chinensis.
