机油乳剂对垫囊绿绵蜡蚧自然种群的控制作用

Control of Petroleum Spray Oils on the Natural Population of Chloropuicinaria psidii

摘要: 通过室内饲养观察和田间系统调查的方法，应用作用因子生命表方法以及在此基础上提出的干扰作用控制指数（IIPC），评价了机油乳剂对垫囊绿绵蜡蚧Chloropuicinaria psidii Mask．自然种群的控制作用．结果表明，在自然条件下，垫囊绿绵蜡蚧的种群趋势指数（I）为7．96；在机油乳剂处理区中，I为0．237，IIPC为0．030，表明机油乳剂对垫囊绿绵蜡蚧的自然种群具有明显的控制作用，防治效果可以达到97％。

Abstract: The life table and interference index of population control(IIPC) were used to evaluate the effect of petroleum spray oils on the natural population of Chloropuicinaria psidii Mask by observation in the laboratory and the systematic investigation in the field.The result showed that the trend index of population(I) of C.psidii was 7.96.The trend index of population in treatment of petroleum spray oils was 0.237,and its IIPC was 0.030.It was indicated that the petroleum spray oils had good control effect of 97% on C.psidii.
