根据田间调查材料,分别以 Holling 圆盘方程、Hassell 和 Varley 模型及 Hassell 和 Roger 模型分析了桔潜蛾姬小蜂对寄主密度的功能反应,对自身密度的功能反应以及对寄主密度,自身密度的共同反应.模拟结果,各参数如下:瞬时攻击率 a=0.1242处理时间 Th=0.1316寄生上限 Na’(∞)=7.6搜索常数 Q=0.5226相互干扰常数 m=0.8126与国内外报导的资料比较,上述参数基本上符合天敌的理想属性,从理论上证明桔潜蛾姬小蜂是有保护利用前途的寄生昆虫。
According to the field survey data, the functional response of the Hyphantria cunea to host density, the functional response to its own density, and the host density, self density The results of the simulation are as follows: instantaneous attack rate a = 0.1242 processing time Th = 0.1316 parasitic upper limit Na ’(∞) = 7.6 search constant Q = 0.5226 mutual interference constant m = 0.8126 Compared with the data reported at home and abroad, The parameters are basically in line with the ideal properties of natural enemies, and it is theoretically proved that the insect is a parasitic insect that has the potential of protection and utilization.
