| 摘 要： | 通过在实验室内研究测定了多异瓢虫成虫、4龄幼虫对苹果绣线菊蚜的捕食作用.结果表明,多异瓢虫成虫及4龄幼虫对绣线菊蚜密度的功能反应能用Holling-Ⅱ型圆盘方程较好地拟合;多异瓢虫成虫及4龄幼虫自身密度的功能反应能用Hassell数学模型较好的反映.多异瓢虫成虫及4龄幼虫对苹果绣线菊蚜有较强的捕食作用,捕食作用在一定范围内随猎物密度的增加而加大,随着自身密度增加而减少.

| Abstract: | The predatory function of the adults and 4th-instar larva of Hippodamia (Adonia) variegata (Goeze) to Aphis citricola Van der Goot in apple trees were tested in lab. The results showed that the equation-II of Holling could describe the functional responses of the adults and 4th-instar larva of Hippodamia (Adonia) variegata ( Goeze) to the density of Aphis citricola. The maths model of Hasse II could reflect their functional responses. The predatory function of the adults and 4th-instar larva of Hippodamia (Adonia) variegata to Aphis citricola is significant, which will increase for more aphids and will decrease for the more oneself density. |
