【摘要】 本文应用生物测定和淀粉凝胶电泳研究了抗阿维菌素灭小菜蛾种群酯酶等位酶多态性。生物测定结果表明:实验种群对阿维菌素抗性为2.23倍。在取样种群中存在高活性的α和β酯酶(EST),其电泳迁移率与致倦库蚊实验参考系均不同。阿维菌来结果分析表明,该种群个体基因型正在向纯合基因型过渡。更多还原

【Abstract】 This paper dealed with the high resistant Abamectin of diamondback moth (DBM), which were collected from YunNan. The resistant levels of the population to abamectin was 2.23 - fold repectively. The results indicated that high - active esterases existed in the population. The Rf is difference from conference population of Culex pipiens. The analysis results by GENEPOP software showed that the genetype of the population were transiting to homozygote.更多还原
