摘　　要：室内研究了七星瓢虫、龟纹瓢虫和异色瓢虫对月季长管蚜与麦长管蚜的捕食功能反应。结果表明,在25℃条件下,3种瓢虫的雌成虫对月季长管蚜与麦长管蚜野生种群的捕食功能反应类型为HollingⅡ型。利用麦夸特迭代算法进行Holling’s圆盘方程分析表明,3种瓢虫对两种蚜虫捕食效率较高。对两种蚜虫处理时间最短的是七星瓢虫,对月季长管蚜攻击系数最高的为异色瓢虫,而对麦长管蚜攻击系数最高的则为七星瓢虫。The predatory functional re- sponses of Coccinella septempunctata, Propylea japonica and Leis axyridis to Macrosiphum rosirvorum and Sitobion avenae were studied in the laboratory. The results showed that the type of all functional responses of female adults was Holhng＇s type II with the temperature of 25℃, and the analysis of Holling＇s disc equation demonstrated that all the predatory efficiency of these ladybirds were high using Levenberg-Marquardt method. Coccinella septempunctata had the most quick predatory time to these aphides, Leis axyridis had the highest attack coefficient to Macrosiphum rosir- vorum, and Coccinella septempunctata had the highest attack coefficient to Sito- bion avenae.
