| 摘 要： | 拟小食螨瓢虫是一种栖息于木薯上的朱砂叶螨的重要天敌。其成虫能捕食朱砂叶螨的各个虫态,随着猎物密度的增加其捕食量逐渐上升,对朱砂叶螨卵、幼螨、若螨和成螨的日捕食量上限分别为146粒,87、91和11头。当猎物密度不变时,随着拟小食螨瓢虫成虫密度的增加,其捕食量下降。

| Abstract: | This paper deals with the functional response of Stethorus parapauperculus to Tetranychus cinnabarinus(Boisduval)and the mutual interferences between predator individuals. With the growth of prey density, the number of preys killed by predators increased gradually. However, when the prey density was constant, the number of preys killed by predators declined while the predator density increasing. |
