摘　　要：本文就七星瓢虫(Coccinella septempunctata Linnaeus)雌雄成虫对豌豆修尾蚜(Megoura iaponica Matsumura)的捕食功能进行了室内研究,经实验表面,七星瓢虫雌雄成虫对豌豆修尾蚜的功能反应均属HollingⅡ型反应。将豌豆修尾蚜设置密度范围为50~250头/皿,七星瓢虫雌雄成虫的捕食量均随着猎物密度的增加而上升,当达到一定密度时,捕食量趋于平缓,雌、雄成虫的日最大捕食量分别为63.29、38.91头/天,在捕食方面表现良好,说明七星瓢虫雌雄成虫对于豌豆修尾蚜有很好的控害能力。所以,本文研究可在七星瓢虫对于豌豆修尾蚜的防治技术上提供相关的理论依据。This paper studies the role of male and female adults of Coccinella septempunctata Linnaeus in feeding on the pea aphidus Megoura iaponica Matsumura.On the surface of the experiment,The functional responses of both male and female Coc⁃cinella septempunctata Linnaeus to Megoura iaponica Matsumura were Holling type.When the density of Megoura iaponica Matsumura was set in the range of 50~250 head/dish,the predation of both male and female adult Coccinella septempunctata Linnaeus increased with the increase of prey density.When the density reached a certain level,the predation tended to rise steadily,and the maximum daily predation of male and female adults were 63.29 and 38.91 head/d,respectively,showing good performance in predation.It indicates that male and female adult beetles of Coccinella septempunctata Linnaeus have a good ability to control the damage of Megoura iaponica Matsumura.Therefore,the study in this paper can provide relevant theoretical basis for the control technology of Coccinella septempunctata Linnaeus against Megoura iaponica Matsumura.
