摘　　要：研究了麦蛾茧蜂对米蛾的功能反应。结果表明,在26±1℃,RH60%～80%,光周期为L∶D=14h∶10h的条件下,麦蛾茧蜂对米蛾的功能反应符合Holling圆盘方程Ⅱ型,其模型为Na=1.078N/(1+0.1091N)。麦蛾茧蜂最大寄生量和最佳寻找密度分别为9.88头和4.75头。麦蛾茧蜂寻找效应随米蛾密度和蜂自身密度的增加而降低,其数学模型分别为:E=1.078/(1+0.1091N)和E=0.295P-0.4012。相互干扰反应模型为:E=0.47P-0.592。以上模型为正确评价麦蛾茧蜂控制米蛾的作用提供了科学依据。Functional response of Bracon hebetor to Corcyra cephalonica was studied. The results showed that the functional responses of B. hebetor to C. cephalonica could be described very well by Holling disc equation Ⅱ , the model was Na=l.O78N/（l＋O.109 1N） under the condition of 26±1 ℃,60%～80% RH and photoperiod L：D=14 h：10 h. The maximum parasitical amount and the optimum searching density were 9.88 and 4.75, respectively. The searching efficiency was decreased with the increase of the density of B. hebetor and C. cephalonica, and their mathematic model was E=1.078/（1＋ 0.109N） and E=0.295Pˉ^0.4012, respectively. The inter-disturbance model was E=0.47Pˉ^0.592. The models concerned provides scientific support for evaluation of the control effect of B. hebetor to C. cephalonica.
