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。
The functional response of M. moth to M. moth was studied. The results showed that at 26 ± 1 ℃, RH60% ~ 80% and L = D = 14h:10h, the functional response of M. moth to M. moth accords with the Holling disk equation Ⅱ, and its model is Na = 1.078N / (1 + 0.1091N). The maximum parasitism and the optimal searching density of B. calyciflorus were 9.88 and 4.75, respectively. The search effect of M. mistica decreased with the increase of M. moth density and its own density. The mathematical models were E = 1.078 / (1 + 0.1091N) and E = 0.295P-0.4012. Mutual interference reaction model: E = 0.47P-0.592. The above model provides a scientific basis for the correct evaluation of the role of the B. calyciflor in controlling M. moth.
