摘要
对白三叶草坪和红花酢浆草草坪春季(4～5月)昆虫群落进行了系统调查。结果表明:白三叶草坪春季昆虫群落由11目20种组成,其中叶螨、蚜虫是该群落的优势种;红花酢浆草草坪春季昆虫群落由11目19种组成,其中叶螨是该群落的优势种。两种草坪群落5月份的主要指标(N、S、H′、J)均大于4月份。两种草坪群落的相似系数为0.718,这些研究为两种阔叶草坪害虫的综合治理提供了理论依据。
By systematic investigation to insect community of Trifolium repens and Oxalis rubra in April to May, 2003,the results showed that the insect community of Trifolium repens Turf consisted of 11 kinds,which belonged to 11 orders.The mite and the aphid were dominant kinds of community. The insect communities of Oxalis rubra Turf consisted of 19 kinds which belonged to 10 orders. The mite was dominant kinds of community. The targets (N. S. H′. J) of two kinds of leafy surf insect community in May were higher than those in April. Index of similarity coefficient of two kinds leafy turf insect community was 0.718 in spring. The results provided theory's basis to IPM of two kinds of turf.
