使用GJ89型粮虫陷阱检测器对中央储备粮重庆北碚直属库高大平房仓储粮昆虫进行了系统调查,并对其群落组成及结构进行了分析.结果表明,高大平房仓储粮昆虫主要有书虱Lipocelis botrychophilus、锈赤扁谷盗Cryptolestes ferrugineus、腐食酪螨Tyrophagus putrescentiae和玉米象Sitophilus zeamais等4类,其中书虱为绝对优势种群;在粮堆垂直方向0～50 cm 4类昆虫发生最多,100～150 cm发生最少;4类昆虫在粮面0～50 cm丰富度、优势度、多样性及均匀度4项指标高于50～100 cm和100～150 cm,水平方向6个区域各项指标差异不大.
By means of GJ89 type of probe trap investigation and analysis of community composition and structure of stored grain insects in large warehouse were carried out in Beibei State Grain Reserve Depot, Chongqing .

The occurrence number of four kinds of stored grain insects were the most at 0- 50 cm grain deep, but a few at 100-150 cm grain deep;The four indexes of richness, dominance, diversity and evenness were higher at 0- 50 cm deep than the other depth.
