六斑月瓢虫是华中、华南地区栖息于蔬菜、果树等作物上的一种重要的食蚜天敌.其成虫能捕食豆蚜、玉米蚜、桃蚜、高售指管蚜和桔二叉蚜等.当5种蚜虫同时存在时,其较喜食桃蚜.在一定的猎物密度范围内,随着猎物密度的增大,其捕食量逐渐增加,两者之间存着密切的相互性.单头成虫对豆蚜、玉米蚜、桃蚜、莴苣指管蚜和桔二叉蚜的日捕食量上限分别为127、141、256、111和233头.当猎物密度不变时,随着捕食者自身密度的增加,其个体日捕食量减小,因而六斑月瓢虫成虫各个体之间在捕食蚜虫的过程中存在相互干扰效应.
Six-spotted ladybug is one of the most important predators in the Central China and South China that inhabit the vegetables, fruit trees and other crops.They can be used as predators of soybean aphid, corn aphid, peach aphid, Etc. When the five kinds of aphids were present, they preferred to eat Myzus persicae.With the prey density increasing, the prey increased gradually with the increase of prey density, and there was a close interdependence between them. The upper limit of daily prey on adult aphids to soybean aphid, corn aphid, peach aphid, lettuce aphid and citrus aphid were 127, 141, 256, 111 and 233. When the prey density remained constant, The increase of their own density, the reduction of their individual daily intake, so there are mutual interference effects between individuals in the predation of aphids.
