| 摘 要： | 花角蚜小蜂具有明显的种内寄生识别能力,友恩蚜小蜂则不具有,可在同一寄主体内重复产卵。采用Lotka-Volterra提出的种间竞争模型进行模拟,花角蚜小蜂和友恩蚜小蜂连续3代种群数量增长的竞争方程为:dN1/dt=2.432 2N1×(91.228 2-N1-0.021 0N2)/91.228 2;dN2/dt=1.854 6N2×(39.071 6-N2-1.965 9N1)/39.071 6。自引种定殖成功后,花角蚜小蜂成为林间控制松突圆蚧的优势种天敌。

| Abstract: | Coccobius azumai Tachikawa could distinguish the hosts parasitized by conspecific parasitoids,while Encarsia amicula Viggiani et Ren could not.En.amicula laid eggs repeatedly in the same host.Lotka-Volterra equation was used to simulate the competition between C.azumai and En.amicula,and after 3 generations,the result was dN1/dt = 2.432 2N1 ×(91.228 2-N1-0.021 0N2)/ 91.228 2;dN2 / dt = 1.854 6 N2 ×(39.071 6-N2-1.965 9N1)/ 39.071 6.C.azumai has become the domimant parasitoid since it was introduced and colonized successfully in Fujian. |
