【中文摘要】 根據1995～1997年在靈芝田對靈芝膜喙扁蝽[Mezira membranacea(Frab)]的調查結果,計算了6種分布型指數,經lwao聚集度指標、Taylor冪法和lwao回歸法測定,結果表明,該蟲在靈芝田呈聚集分布,其分布強度隨種群密度的升高而增強。聚集原因既有環境因子,又有該蟲本身的特性。同時建立了該蟲的理論抽樣公式。

【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.
