摘要
经测定 ,七星瓢虫成虫、4龄幼虫和大草蛉 3龄幼虫对桃粉蚜的捕食功能反应属于 Holling- 型圆盘方程式 ,两种天敌对桃粉蚜具有较强的捕食能力。
The functional response of Coccinella septempunctata and Chrysopa septempunctata to Hyalopterus amygdali were studied through laboratory experiments. The results showed that they belonged to Holling-Ⅱ model. These two natural enemies had high efficiency to control Hyalopterus amygdali.
