| 摘 要： | 稻秆蝇在晚稻田为害呈聚集分布。应用Iwao的X-X回归法、Taylor幂指法、Southwood公共Kc值法求得三个理论抽样数模型，并由Iwao的X-X回归法导出最适抽样单位。当采用Iwao及Willsoo等（1983)提出的序贯抽样法时．得到两个序贯抽样模型。结合Iwao的X-X回归法。Taylor幂指法、Southwood公共Kc值法等三模型，Iwao和Willson的二模型．获得了该虫的复合理论抽样法和复合序贯抽样法。

| Abstract: | The damage of Chlorops oryzae Matsumura displayed clustering pattern of distributionin late rice fields.Tbree theoretical models for sampling number were developed based on themethods of Iwao's x-x regression,Taylor's power index and Southwood's common value ofKc.The optimal unit for sampling was also obtained from lwao's x -x regression.Two modelsfor sequential sampling were obtained from the methods developed by Iwao and Willson(1983).An integrated method of theoretical sampling and sequential sampling for Chloropsoryzae was de-veloped based on the previous models. |
