摘　　要：贮粮害虫是为害贮藏期间粮食及其产品的害虫的统称。经过长期的演变与自然选择,大部分逐渐适应了粮仓(室)内的生活环境,终生生活在仓内,有些种类在田间与粮仓之间交替为害,但在仓内繁殖为害比田间更为严重。通过调查贮粮害虫的种类、优势种及群落类型分布等,明确目标,并结合生产实践提出相应的防控对策。Grain Reserve Pests are pests that are harmful to reserved grain and related grain products. After a series of evo- lution, some pests have already adapted to the environment inside and outside granary. Some of them live inside, while oth- ers shift from inside the granary to the field and make a living between. Both cases are causing disturbing effects on the grain reserve, but the reproduction of these pests are causing more serious effects inside granary than outside in the field. By investigating into the variety of pests, distribution patterns and what variety has higher productivity, solutions in agricul- tural practice were put forward in this paper.
