【摘要】：目的了解德国小蠊抗高效氯氰菊酯品系抗性遗传方式。方法选取德国小蠊对高效氯氰菊酯的抗性品系60只为材料,通过生物测定方法和一系列杂交、回交和自交试验,测定德国小蠊对高效氯氰菊酯杀虫剂的抗性遗传方式。结果杂交品系RS、SR的抗性倍数分别为2.356和2.429,抗性显性度D值分别为0.236和0.279,均介于0~1;回交(RS×SS)后代BC和自交(RS×RS)后代F2的∑χ2分别为12.337 8和37.686 9,均χ20.05(11.07)。结论德国小蠊抗高效氯氰菊酯品系抗性遗传方式为常染色体不完全显性遗传,并且抗性是由多基因控制。
[Abstract]:Objective to understand the genetic pattern of resistance to cypermethrin in cockroach germanica. Methods 60 strains of Blattella germanica resistant to high efficiency cypermethrin were selected as materials. The genetic pattern of resistance of Blattella germanica to high efficiency cypermethrin was determined by bioassay and a series of cross, backcross and self-crossing tests. Results the resistance ratio of cross line RSN SR was 2.356 and 2.429, the resistance dominance D value was 0.236 and 0.279, respectively, and the 鈭，
