摘　　要：根据高粱粟穗螟幼虫田间种群空间分布型的研究结果,应用序贯抽样,零频率抽样技术,给出了幼虫田间种群密度估计的Kuno、Iwao指导防治的序贯抽样表和抽样图,Gerrard和Chiang零频率种群密度估计表,不同虫口密度、抽样精度下的理论抽样数。In this paper, the sequential sampling and zero frepuency techniques for the larva population of foxtail Millet Webworm (.Mampora bipunctella Rogonot) was used by means of computer simulationt the Kuno and Iwao's sequential sampling and Gerrard's simple sampling charts and tables for estimating the density of the larva population in sorghum fields, was also presented.
