The present study was conducted to control cabbage (Brassica oleracea L. var. capitata L. ) pests with several insecticides of 30 % chlorantraniliprole . thiamethoxam SC, 25 % chlorantraniliprole SC and 40 % chlorpyrifos EC applied by drenching to seedbeds. The results showed that 30 % chlorantranilip-role. thiamethoxam SC had high control effect and longer duration against diamondback moth (Plutellaxy lostella) and striped flea beetle (Phyllotreta vittata) on cabbage. Ten days to twenty-five days after transplanting, the control efficacy of 30 % chlorantraniliprole . thiamethoxam SC was over 89 %, which was equal to 25 % chlorantraniliprole SC by 48. 75 g . hm -2 and very significantly better than that of other insecticides. Seventy days after transplanting, field investigations found that different treatments had significant different impacts on cabbage fruit setting. Among them, the effects of 30 % chlorantraniliprole . thiamethoxam SC had the lowest cabbage fruit setting rate.
