摘    要:害虫的抗性遗传特性是影响其抗性发展的一个重要因子,也是制订抗性治理对策的重要依据。我们采用稻茎浸渍法测定了褐飞虱Nilaparvatalugens (Stal)抗性和敏感亲本、正反交(F1、F12、F'2)及回交(BC)后代3龄若虫对噻嗪酮的剂量反应数据,研究了褐飞虱对噻嗪酮的抗性遗传特性。结果表明: 正反交后代的显性度分别为-0.3153(F1)和-0.376 3(F'1),表明抗性遗传为常染色体的不完全隐性;将自交及回交后代的剂量反应数据进行单个主基因假设的卡方(χ2)检验,其卡方值分别为42.11(F2)、5.44 (F'2)及93.57(BC),均大于χ0.05= 15.51(df=8),表明其抗性是多基因控制的。还讨论了褐飞虱对噻嗪酮的抗性治理策略。

关 键 词:褐飞虱  稻茎浸渍法  噻嗪酮  抗性遗传

Abstract:The inheritance of pest-insect's resistance to insecticide is not only an important factor affecting the development of resistance but also the basis for formulating resistance management strategy. The inheritance of resistance to buprofezin in the brown planthopper, Nilaparvata lugens (Stal),was studied through assaying dose-response data of the third nymhs of resistant® and susceptible(S) parents, reciprocal crosses (F1 and F'1), self-bred (F2 and F'2) and backcross (BC) progenies to buprofezin with the rice-stem dipping method. The results showed that the main resistant gene was autosomal and incompletely recessive, with degree of dominance (D) -0.3153 (F1) and -0.3763 (F'1); the chi-square analysis results of the dose-response data of F2, F'2 and BC pr ogeny was 42.11, 51.44 and 93.57 respectively, all higher than χ2 0.05=15.51(df=8), indicated that buprofezin resistance in the brown planthopper appears to be controlled by two or more genes. The resistance management tactics of N. lugens to buprofezin is also discuss ed here.
Keywords:Nilaparvata lugens  rice-stem dipping method  buprofezin  inheritance of resistance
