【中文摘要】 根据1995～1997年在灵芝田对灵芝膜喙扁蝽[Mezira membranacea(Frab)]的调查结果,计算了6种分布型指数,经lwao聚集度指标、Taylor幂法和lwao回归法测定,结果表明,该虫在灵芝田呈聚集分布,其分布强度随种群密度的升高而增强。聚集原因既有环境因子,又有该虫本身的特性。同时建立了该虫的理论抽样公式。
【英文摘要】 Based on the preliminary survey of Mezira membranacea (Frab.) in Ganoderma lucidum field from 1995 to 1997, six distribution pattern indexes had been calculated. Three theoretical models of analysis were developed by Iwao's index of aggregation (M/X), Taylor's power law (S2 = aXb) and Iwao's (M-X) regression (M =α+βX). The results showed that the spatial distribution patterns of M. membranacea were aggregated both at larva and adult stages in G. lucidum field. The aggregation level was increased with the increasing of the insect population density due to the environmental factors and the bionomics of the insect. While the theoretical sampling formulas for larvae and adults were also established.
