| 摘 要： | 为评价非昆虫源人工饲料饲养七星瓢虫的捕食能力，在室内比较了用人工饲料饲养的七星瓢虫种群和蚜虫饲养的七星瓢虫种群对豆蚜捕食作用的异同。结果表明，两种七星瓢虫种群各虫态的捕食量均随着猎物密度的增加而上升，当猎物密度增加到一定水平，捕食量趋向稳定，捕食功能反应曲线均符合Holling Ⅱ型方程。人工饲料饲养种群的1～4龄幼虫、雌成虫和雄成虫的理论最大日捕食量分别是20.9、36.0、100.2、403.2、490.9和395.3头，蚜虫饲养种群的1～4龄幼虫、雌成虫和雄成虫的理论最大日捕食量分别是20.0、28.9、102.1、476.2、472.2和396.4头。结果说明两种种群各虫态对豆蚜的最大日捕食量差异不大，表明人工饲料饲养的七星瓢虫对豆蚜也有较强的控制作用。

| Abstract: | Coccinella septempunctata were reared on non-insect ingredients artificial diet and the difference of predatory capacity of C. septempunctata to Aphis craccivora was investigated between the diet-fed and aphid-fed beetles in the laboratory. The results showed a positive relationship between the preyed amount and prey density. The predatory functional response of C. septempunctata fitted well with Holling's equation Ⅱ. The maximal theoretical predation capacities of 1st, 2nd, 3rd, 4th instars, female and male adult of C. septempunctata reared on diet were 20.9, 36.0, 100.2, 403.2, 490.9, and 395.3 per day, respectively; those for the C. septempunctata reared on aphids were 20.0, 28.9, 102.1, 476.2, 472.2, and 396.4 per day, respectively. The results indicated no significant difference in the predatory capability between the diet-fed and aphid-fed beetles, suggesting that it is feasible to rear C. septempunctata using the diet. |
