The prevention and treatment effect of plan-d erived compound insecticide on tobacco aphid and on predators of tobacco aphid was studied by the method of field investigation and laboratory rearing,combining with statistical results.The experiment indicated that the ideal applied concentration of plant-derived compound insecticide was 400 times and 600 times,both of which had a significant killing effect on tobacco aphid,and no negative influence on predators of tobacco aphid.The effect of 400 times was slightly better,but the difference between was not significant,600 times was recommended.
