Abstract: In order to explore the effects of kidney bean resistant and susceptible varieties on the growth and development of Aphis craccivora，the activities of digestive enzymes（lipase，protease，α‑amylase）and detoxification enzymes（glutathione‑S‑transferase，carboxylesterase，acetylcholinesterase）in the body of A.craccivora fed on kidney bean resistant and susceptible varieties were determined，and the life table of A.craccivora population continuously reproducing for three generations on kidney bean resistant and susceptible varieties was constructed.The results showed that the activities of three digestive enzymes，carboxylesterase and acetylcholinesterase in A.craccivora after feeding on susceptible kidney bean varieties were significantly higher than those of A. craccivora after feeding on resistant varieties，but the activity of glutathione‑S‑transferase in A.craccivora after feeding on resistant varieties was significantly higher than that on susceptible varieties，and the increase was 12.9%.The survival rate of F₂ and F₃ generations of A.craccivora parasitized on aphid‑resistant varieties decreased compared with F₁ generation，and the number of A.craccivora gradually decreased，while those on the susceptible varieties were the opposite.The net value‑added rate（R₀）of the F₃ generation on the susceptible variety was 28.60，while that on the resistant variety was only 11.13，and there was a significant difference.In conclusion，after feeding on the insect‑resistant kidney bean variety，the activities of digestive enzymes，carboxylesterase and acetylcholinesterase in the bodies of A.craccivora decreased，while the activity of glutathione‑S‑transferase increased，and the survival rate of their offspring and the number of aphids produced decreased.However，the opposite was true when they fed on the susceptible kidney bean varieties.

摘要： 为了探究芸豆抗、感品种对豆蚜生长发育的影响，测定了豆蚜取食芸豆抗、感品种后体内消化酶（脂肪酶、蛋白酶、α-淀粉酶）和解毒酶（谷胱甘肽-S-转移酶、羧酸酯酶、乙酰胆碱酯酶）活性的变化，并构建了芸豆抗虫、感虫品种连续繁衍3代的豆蚜种群生命表。结果表明，豆蚜取食感虫芸豆品种后体内3种消化酶、羧酸酯酶以及乙酰胆碱酯酶活性均极显著高于取食抗虫品种后的豆蚜个体，但豆蚜取食抗虫品种后体内的谷胱甘肽-S-转移酶活性极显著高于感虫品种，增幅为12.9%。寄生于抗蚜品种上的豆蚜F₂、F₃代存活率相比F₁代有所下降，产蚜量也逐渐降低，感虫品种则相反。感虫品种日本红上豆蚜F₃代的净增殖率（R₀）为28.60，而抗虫品种仅为11.13，存在极显著差异。综上，豆蚜取食芸豆抗虫品种后体内的消化酶、羧酸酯酶以及乙酰胆碱酯酶活性降低，谷胱甘肽-S-转移酶活性提高，后代存活率和产蚜量降低，而取食芸豆感虫品种后则相反。
