Abstract
Esterase activity of resistant and susceptible H. armigera were compared in gels with different substrate such as naphthyl acetate, naphthyl phosphate, paraoxon and monocrotophos. Whole body extract of resistant H. armigera hydrolyzed paraoxon, monocrotophos and naphthyl phosphate in gels. Resistant H. armigera showed high esterase, phosphatase and paraoxon hydrolase activity compared to susceptible ones.
摘要
在含有不同底物（如乙酸萘酯、磷酸萘酯、对氧磷和久效磷）的凝胶中比较了抗性和敏感棉铃虫的酯酶活性。抗性棉铃虫的全身提取物在凝胶中能水解对氧磷、久效磷和磷酸萘酯。与敏感棉铃虫相比，抗性棉铃虫表现出较高的酯酶、磷酸酶和对氧磷水解酶活性。
