摘要
龟纹瓢虫(Propylaeapponica(Thunbery))成虫对麦长管蚜(Macrosighumavenae(Fabridu))和棉蚜(AghisgossypijGlove)的功能反应属HollingⅡ型,功能反应模型分别为和。在两种不同蚜虫的猎物条件下,龟纹瓢虫成虫寻找效率和自身密度的关系分别可用E=0.4350P-0.8364和E=0.4928P-0.7637模型进行描述,表明龟纹瓢虫寻找效应随自身密度的增大而下降,并随猎物种类的不同而有所不同,瓢虫成虫个体间存在明显的干扰效应。
The functional response of Propylea japonica(Thunbery) to wheat aphids,Macrosiphum avenae (Fabricius) and cotton aphids, Aphid gossypii Glover belongs to Holling Ⅱ,.The models of functional response of the ladybird to the twohaphids are respectively Under the condition of different preys, the relationship between searching efficiency and the number of theladybirds can be quantitatively measured with the following modelrespectively; E = 0.4350p-0.8364 and E=0.4928P-0.7637, which show a servers mutual interference among the ladybirds.
