摘要
一种蚜小蜂Aphelinussp . 对麦双尾蚜Diuraphis noxia (Mordvilko) 的功能反应为HollingI型, 直线方程为Na = 0-6060N- 3-4700 。七星瓢虫Coccinella septempunctata L. 成虫对麦双尾蚜功能反应也为I型, 直线方程为Na = 0-6020N+ 5-9000 ; 多异瓢虫Hippodamia variegata Goeze成虫和斑腹蝇Leucopisannulipes Zett.3 龄幼虫对麦双尾蚜的功能反应均为II型, 关系式分别为1/ Na = 1-2550/ N+ 0-0046 和1/ Na = 1-3280/ N+ 0-0071。
The functional responses of four species of natural enemies to the Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), were examined in laboratory in Xinjiang Uygur Autonomous Region. The responses of Aphelinus sp. and Coccinella septempunctata to RWA was showed to be the Holling I type and could be fitted by N a = 0 6060 N -3 4700 ( n ≤100) and N a = 0 6020 N +5 9000 ( n ≤250) respectively, where N a is number of the aphids attacked and N , the initial number of the aphids. The predation of Hippodamia variegata and Leucopis annulipes on the aphid could be well described by Holling II type, with the models as 1/ N a = 1 2550/ N +0 0046 and 1/ N a = 1 3280/ N +0 0071 respectively.
