| 摘 要： | 在组建小菜蛾自然种群生命表的基础上，应用种群趋势指数和干扰作用控制指数，评价小菜蛾颗粒体病毒对小菜蛾种群的控制作用．试验结果表明：施用颗粒体病毒制剂后，其种群趋势指数为5．99，干扰作用控制指数为023．即，其下代数量明显下降．可见，小菜蛾颗粒体病毒对小菜蛾种群的控制作用是明显的．

| Abstract: | In this paper, the life tables of natural population and the intefference index of populationcontrol (IIPC) were used to evaluate the effectiveness of Plutella xylostella Granulosis virus (PxGV) onthe population dynamics of diamondback moth. The results show that PxGV sprayed gave the index ofpopulation trend (I) as high as 5 .99, the IIPC as high as 0.23. It suggests that the population size ofthe nex generation will be decreased to O. 23 times as against the original. It show a general effectivenessof PxGV on the population of diamondback Moth. |
