阿维菌素汰选的小菜蛾抗性种群 (ABM- R)与相对敏感种群 (ABM- S)相比不表现繁殖不利性。 ABM- R种群的交配率、有效产卵指数和孵化率均显著大于 ABM- S种群 ,ABM- R种群的内禀增长率为 0 .139,是 ABM- S种群的 1.19倍 ,相对适合度为 ABM- S种群的1.4 9倍。建立了 ABM- S和 ABM- R种群的生命表 ,并对抗性治理进行了讨论。
The abamectin-eliminated diamondback moth resistant population (ABM-R) did not show reproductive disadvantage compared to the relatively sensitive population (ABM-S). The mating rate, effective spawning index and hatching rate of ABM-R population were significantly higher than that of ABM-S population. The intrinsic rate of increase of ABM-R population was 0.139, 1.19 times that of ABM-S population, the relative fitness was 1.4 9 times of ABM-S population. The life tables of the ABM-S and ABM-R populations were established and the resistance management discussed.
