摘要
在实验室条件下,初步研究了二双斑唇瓢虫对朝鲜球坚蚧的捕食作用,采用Holling-Ⅱ型方程和Holling-Ⅲ型功能反应模型对二双斑唇瓢虫捕食朝鲜球坚蚧的作用进行拟合。结果表明,1头二双斑唇瓢虫成虫对朝鲜球坚蚧的最佳寻找密度为32 65头,其寻找效应随着猎物密度的增加而降低。
The predacious function of Chilocorus bijugus Mulsant to Didesmococcus koreamus Borché. were pilot studied in the laboratory. The predaceous role of Chilocorus bijugus Mulsant to Didesmococcus koreamus Borché. was simulated with the mathematical models of Holling-Ⅱ and Holling-Ⅲ. The results showed that the best seeking density of Chilocorus bijugus Mulsant adult was about 32.65. The seeking effect of the ladybird decreased with the increase population density of its prey.
