摘要
在室内对孟氏隐唇瓢虫成虫自残幼虫的行为以及雌虫取食幼虫后的生殖力进行了研究,结果表明,雌成虫在48h内残杀幼虫造成的死亡率为60%,显著高于雄成虫;与其他部位相比幼虫的腹部遭受更多地攻击,幼虫体表覆盖的蜡丝在一定程度上抵御了成虫的攻击。与取食粉蚧的雌虫相比,取食瓢虫幼虫的雌虫产卵率和平均产卵量均显著降低。
The cannibalism behavior of adults to larvae in Cryptolaemus morttrouzieri, and the fecundity of females reared on larvae were studied in laboratory. The results showed the mortality of larvae canni- balized by females in 48 hours was 60%, which was higher than males did. And compared the other body parts, the abdomen of larvae were attacked more by females. However, to a certain extent the wax covers on larvae was able to defense the attack by adult. The oviposition rate and average fecundity of females fed on larvae were lower than fed on mealybugs respectively
