| 摘 要： | 通过连续观察小黑瓢虫捕食烟粉虱的行为,发现小黑瓢虫似乎利用“试错法”来觅食,采取积极搜索式为主,偶见坐等捕食式的捕食策略。瓢虫成虫的捕食行为全过程有6个部分:搜寻、取食、梳理、静息、展翅、排泄;瓢虫幼虫无展翅行为,且梳理和排泄行为较少发生。

| Abstract: | After continuous observation Delphastus catalinae(Horn) to prey on Bemisia tabaci(Gennadius),it is found that D.catalinae uses the method of trial and error to feed,and mainly adopts the strategy of actively searching,once in a way is sitting back and wait.The predatory behavior of adult D.catalinae consists of six actions: searching,feeding,grooming,resting,wingspreading and excretion.The larva has the same but without wingspreading,and grooming and excretion happened occasionally. |
