七星瓢虫三四龄幼虫捕食四种蚜虫功能反应初步研究
Preliminary Study on Prey Functional Response of the 3rd-and 4thinstar Larva of Coccinella septempunctata on Four Species of Aphid
摘要
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 maximum 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.关键词
