| 摘 要： | 根据田间调查与室内研究,组建了1986和1987两年褐稻虱田间第6代种群平均生命表.通过重要生态因子的作用效果分析,进一步表明影响第6代种群变动的重要因子为自然天敌,在此基础上,利用生命表的资料,把矩阵模型与差分方程结合起来,构造了褐稻虱田间种群动态的模拟模型,在计算机上逐日模拟褐稻虱的种群动态,其结果与田间实测值基本一致;同时又探讨了此模型与天敌作用模型的耦联模拟情况.由此表明此模型可用于自然变温条件下褐稻虱田间种群数量和发生期的预测.

| Abstract: | The mean life table of the 6th generation of the natural population of brown planthopper Nilapavata lugens(BPH)in 1986 and 1987 is constructed according to the out- door surveys and indoor experiments.The analysis of the effect of the important ecology fac- tors has been madefurther to indicate that the important factor affecting the population dynamicof the 6th generation is natural enimies.Based on the data of the life table,the simulation model of BPH's population dynamics in the fields has been built by means of the combination of different equation and the matrix model.On the whole,the predicted results of the population dynamic are similar to thosedetermined in the fields.Furthermore,it is possible to simulate the population dynamic by coupling the dynamic model and the enimiesaffecting model.Thus,it has been indicated that the model can be used to predict the time of the developmental stage as well as the number of the population under natural condi- tions. |
