梨茎蜂卵空间分布型及抽样技术研究

文章对梨茎蜂卵的空间分布型及抽样技术进行了研究，结果表明；梨茎蜂卵为聚集分布。用泊松、奈曼、负二项分布的三种公式进行拟合表明，卵为负二项分布。文章还列出了不同允许误差下的理论抽样数表及不同防治阀值的序贯抽样表。

Study on Distribution Pattern and Sampling Technique of Eggs of Janus Piri

In this paper,distribution pattern and sampling technique of eggs of Janus piri had been studied. The results showed that eggs of Janus piri were gathing distribution. Imitating by three formulas of Poisson,Neyman and negative binomial distribution showed that the distribution pattern of eggs of Janus piri was negative binomial one. Theoritical sampling numbers table under different permissible error scope and sequentical sampling table under different control limits had been listed.
