Abstract： [Objectives] To provide a scientific basis for selecting pesticides to control the soybean aphid, Aphis glycines (Hemiptera: Aphididae). [Methods] The effectiveness of ten insecticides on A. glycines was tested in the laboratory and in the field. [Results] The results of laboratory toxicity experiments show that corrected mortality ranged from 85.84% to 100% after 24h. The results of field trials show that only one of the insecticides tested, spinosad 2.5% SC, was ineffective in controlling A. glycines. The corrected control effects of pyrethrin 15% EW, spinetoram 6% SC, abamectin 3% EW and matrine 0.5% EW were > 95% after 4 d. [Conclusion] These four biopesticides are broadly popular and can be an effective means of controlling A. glycines.
