    CONTROL EFFECTS OF THE PREDATORS ON BROWN PLANTHOPPER POPULATION

      摘要
    • 摘要: 本文将集中作用于褐稻虱若虫和成虫期的稻田捕食性天敌归纳为4个类群、分别作用于褐稻虱种群1～2龄若虫、3～5龄若虫和成虫3个状态,应用五因子二次回归正交旋转组合设计方法进行试验,结合生命表资料,建立褐稻虱这3个状态的控制指数方程,通过状态空间分析法和控制指数的综合分析,结果表明,稻田捕食性天敌对褐稻虱种群的控制作用是明显的。

       

      Abstract: The control effects of the predators on the population of the brown planthopper,Nilaparvata bugens was studied in the light of rotation composite design of regression and the state-space method in this paper.The main predators in paddy field in Hailing Island in Guangdong province as the object population for constructing the equation of populations control index(IPC).It was emphasized that the state-space metod and IPC could be used to study the integrative control effcts of the predators on pest insects.
