【中文摘要】 根據(jù)1995~1997年在靈芝田對(duì)靈芝膜喙扁蝽[Mezira membranacea(Frab)]的調(diào)查結(jié)果,計(jì)算了6種分布型指數(shù),經(jīng)lwao聚集度指標(biāo)、Taylor冪法和lwao回歸法測(cè)定,結(jié)果表明,該蟲(chóng)在靈芝田呈聚集分布,其分布強(qiáng)度隨種群密度的升高而增強(qiáng)。聚集原因既有環(huán)境因子,又有該蟲(chóng)本身的特性。同時(shí)建立了該蟲(chóng)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.
