Institute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou 350013

摘要: 矩形拟矮蒲螨Pseudopygmophorus quadratus Ewing在蘑菇菇床上的分布经Tanlor的S2=axb及Iwao的m=x+βx检验,其若螨、成螨、成若螨的分布的基本成分为各个个体之间是相互排斥的个体群,和各个个体群之间聚集的聚集分布。根据三种抽样法及最适抽样数比较,认为在蘑菇菇床上以对角线14个样点取样为最佳。

Abstract: The spatial distribution patterns of the nymph, nymphadult, adult mite, P. quadratus Ewing, were tested by means of the Iwao equation m= α+βx and the Taylor equation S2 = axb respectively. The results showed that all the distribution patterns tested belonged to aggregative one. The 3 types of sampling methods: Diagonal, Paralled and Scattering were involved in the experiment. The optimum sampling method was the Diagonal one with 14 sampling points for the mite.
