| 摘 要： | 根据七星瓢虫对不同寄主的捕食、衔接转移的特性,将三、四龄幼虫对棉蚜、麦蚜,大豆蚜、萝卜蚜捕食功能反应进行了试验,并分别建立了捕食功能反应数学模型。日最大捕食量三龄幼虫分别为86.6、71.6、86.4头和82.5头,四龄幼虫分别为155.3、121.8、170.1头和145.6头。同时,进一步试验验证瓢虫高龄幼虫转移时的捕食功能和特性,仍存在"抢食"和"补食"的现象。

| Abstract: | Based on the predation and bridging transfer characteristics of Coccinella septempunctata on different hosts of wheat, cotton, soybean and radish, its prey functional response of the 3rd - and 4th - instar larva on four species of aphid was tested and the functional response models were established. The daily maxi- mum predation number of the 3rd - instar larva was 86.6, 71.6, 86.4 and 82.5 respectively, while that of the 4th - instar larva was 155.3, 121.8, 170.1 and 145.6 respectively. At the same time, further experiment on predation function and characteristics during transfer of high - instar larva, the phenomenon of snatch and supplements was also observed. |
