【摘要】：目的了解德國(guó)小蠊抗高效氯氰菊酯品系抗性遺傳方式。方法選取德國(guó)小蠊對(duì)高效氯氰菊酯的抗性品系60只為材料,通過(guò)生物測(cè)定方法和一系列雜交、回交和自交試驗(yàn),測(cè)定德國(guó)小蠊對(duì)高效氯氰菊酯殺蟲(chóng)劑的抗性遺傳方式。結(jié)果雜交品系RS、SR的抗性倍數(shù)分別為2.356和2.429,抗性顯性度D值分別為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分別為12.337 8和37.686 9,均χ20.05(11.07)。結(jié)論德國(guó)小蠊抗高效氯氰菊酯品系抗性遺傳方式為常染色體不完全顯性遺傳,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，
