摘　　要：采用ＧＪ８９型粮虫陷阱检测器对书虱在房式仓和土堤仓中的分布进行了调查研究，结果表明书虱分布有显著的差异性。房式仓中书虱分布呈明显的越南性和趋西性，且由南向北虫口密度逐渐减少，由东向西虫口密度逐渐增加。对房式仓不同粮层（０～０． ５ｍ、１． ５～２ｍ、３～３．５ｍ）的研究结果表明在垂直方向上书虱分布差异并不显著，但虫口密度随着粮堆深度的增加而降低、用聚集度各项指标检验表明，书虱在粮堆中是聚集分布，且在粮堆下层聚集度最大。土堤仓中书虱分布也呈现显著的差异，其脊部区域明显高于其它区域，西部虫口密度明显高于东部，南部虫口密度明显高于北部。对土堤仓不同层次（０～０．５ｍ、１，５～２ｍ、３～３．５ｍ）的检测结果表明在垂直方向上书虱分布差异显著，用聚集度指标分析表明各层均呈聚集分布。Population distribution characteristics and pattern of liposelis spp. were determined in wheat in a horizontal storage and a bunker with GJ89 probe traps. In the horizontal storage, liposcelis spp. occurred regularly in high numbers in the south, the west and the upper, and the numbers decreased gradually to the opposite direction. In the bunker, the density of Li poscelis spp. reduced from the central apex of the grain bulk towards the floor and edges. The number per sample in the central apex was significantly higher than other positions, and the same as the south to the north, the west to the east. Application of mean crowed index and other methods revealed a clumped distribution for this genus in ho these two kinds of stor age and which was possibly due to its contiguous propensity.
