为明确饥饿情况下蠋蝽种内残杀行为的发生时期和影响因素,指导蠋蝽规模化繁育和释放,本文研究了不同发育时期和密度下的蠋蝽种内残杀行为.研究发现:蠋蝽对卵粒的种内互残行为主要发生在饥饿24 h以内,雌性蠋蝽对卵粒的取食行为显著强于雄性蠋蝽,取食比例是雄性的2.80～3.25倍、取食量是雄性的18.75～21.20倍,雌性取食下的卵粒羽化率为70.66％,显著低于雄性和对照的86.59％和87.88％.发育时期和饲养密度均显著影响蠋蝽的种内残杀行为,主要发生在饥饿后的19.63～36.00 h,并且1、2、3龄若虫没有表现出种内残杀行为,4龄以后种内残杀行为显著;低密度下蠋蝽种内互残行为不显著,但高密度会增强种内互残行...

In order to clarify the occurrence period and intraspecific cannibalism behavior of A.chinensis under starvation and guide the large-scale breeding and release of A.chinensis,we investigated the intraspecific cannibalism behavior in different developmental stages and densities.The results showed that predation behavior of A.chinensis to eggs mainly occurred within 24 hours after starvation.The intraspecific cannibalism behavior of female to eggs was significantly stronger than that of male.The predation proportion of female was 2.80―3.25 times...
