| 摘 要： | 在实验室内测定了多异瓢虫成虫,各龄幼虫对豆无网长管蚜的捕食作用,结果表明,多异瓢虫成虫及4龄幼虫对豆无网长管蚜有较强的捕食作用;多异瓢虫成虫及各龄幼虫对豆无网长管蚜密度的功能反应符合Holling-Ⅱ型;多异瓢虫成虫自身密度的功能反应能用Hassell数学模型较好地反映。

| Abstract: | The predatory function of the adults and larvae of Hippodamia (Adonia) variegata (Goeze) to Acyrthosiphon pisum (Harris) were tested in the laboratory. The results showed that the adults and 4th-instar larvae of Hippodamia (Adonia) variegata had a strong predatory function to Acyrthosiphon pisum and the functional responses of the adults and larvae of Hippodamia (Adonia) variegata to the density of Acyrthosiphon pisum accorded with Holling-Ⅱ. The math model of Hassell could reflect its self-density functional responses. |
