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。 Stored grain pests are collectively referred to as pests that damage food and its products during storage. After long-term evolution and natural selection, most of them gradually adapted to the living environment in the granary (room) and lived in their wares for life. Some species were alternately damaged in the fields and silos, but their reproduction in the warehouses was more serious than that in the fields . By investigating the types of stored grain pests, the dominant species and the distribution of community types, the objectives were clarified and the corresponding prevention and control measures were put forward according to the production practices.
