摘要
室内试验表明 ,迷宫漏斗蛛雌、雄蛛对假眼小绿叶蝉的捕食功能反应均为HollingⅡ型反应 ,迷宫漏斗蛛对假眼小绿叶蝉的控制能力雌蛛大于雄蛛。捕食量上限雌蛛为 2 95 3头 ,雄蛛为 12 0 7头 。
The predatory functional responses of Agelena labyrinthica (Clerck) to Empoasca (Empoasca) vitis (Gthe) were studied in laboratory. The results showed that the functional responses of both male and female spiders belonged to Holling's Ⅱ type. The control ability of the female predator of A. labyrinthica (Clerck) to the prey E. (Empoasca) vitis (Gthe) was larger than the male spiders, and their predatory upper limits were 295.3 adults and 120.7 adults, respectively. This suggested that the spiders had larger potential in controlling the leafhoppers. The feeding pattern of A. labyrinthica (Clerck) was also observed.
