摘　　要：2009年在黑龙江省3个有代表性大豆产区采集大豆蚜,用浸叶法分别对有机磷、氨基甲酸酯类等10种化学药剂进行敏感度测定,得到大豆蚜对10种药剂的LC50值和相对毒力指数,发现三地大豆蚜对有机磷类农药已产生了轻微的抗性,对阿维菌素和高氯两类药剂最敏感。Aphis glycines were collected in primary grain crop production region of Heilongjiang Province.The resistance of Aphis glycines to 10 commonly used insecticides was tested by leaf-dipping method.LC50 and relative toxicity ratio of Aphis glycines were gotten to provide reference for controlling Aphis glycines effectively.The results showed that Aphis glycines had light resistance to organophos-phorus pesticide,and it was sensitive to avermectins and cypermethrin.
