| 摘 要： | 试验研究了七星瓢虫对刺槐蚜和绣线菊蚜的捕食功能反应．捕食者与猎物的功能反应均属于ＨｏｌｉｎｇⅡ型，经Ｘ２测验，其理论值与观察值很接近，说明模拟后的各方程可用来描述瓢虫的功能反应．七星瓢虫对刺槐蚜和绣线菊蚜的理论最大捕食量，三、四龄幼虫明显大于一、二龄幼虫．而且七星瓢虫对不同蚜虫的捕食量有一定的差异

| Abstract: | The functional responses of ladybird,C.septempunctata L to prey on A.robiniae Macchiati and A.citricolas Van der Goot were investigated in the laboratory.The functional responses of the predators to the prey can be described by the models of Holling Ⅱ,applying the weighted methods ofr linearization after the Holling disk equation had been linearized.X 2 test showed that the theoretical expectation fits the observe values.The catching numbers of larvae of ladybird to A.citrcola are larger than those of ladybird to A.robiniae |
