The aim of this research is to select high-efficiency, low-toxicity and safe insecticides for the control of Apolygus lucorum, and to provide basic data and scientific basis for the scientific prevention and control of A. lucorum. The laboratory toxicity and field control effect of different insecticides on A. lucorum were studied. In this study, the laboratory toxicity and field control effect of thiamethoxam, abamectin, matrine, rotenone and osthole on A. lucorum were determined by food dipping method and field spraying method. The results of laboratory toxicity test showed that the toxicity of five insecticides to A. lucorum increased with the increase of insecticide concentration. The order of toxicity to A. lucorum was thiamethoxam > abamectin > matrine > rotenone > osthole. The results of field control test showed that 300 mg/L thiamethoxam and 600 mg/L thiamethoxam had the best control effect after 3 days of application in mung bean field, and the field control effect had reached more than 75%. After 7 days of application in mung bean field, the control effect of 600 mg/L thiamethoxam was the best, followed by 300 mg/L thiamethoxam and 1000 mg/L avermectin, and the field control effect was more than 70%. The field control effect of 1600 mg/L matrine was 58.94%, and the field control effect of 1600 mg/L rotenone and 1600 mg/L osthole was about 50%. It was found that five insecticides had certain field control effects on A. lucorum, among which thiamethoxam and abamectin had better control effect on A. lucorum, and they were recommended to be utilized in the field.
