采用GJ89型粮虫陷阱检测器对钢板仓害虫物种分布组成及主要害虫书虱和螨类在不同储藏期各部位的分布进行了调查研究。结果表明 :3～ 4月仓库昆虫物种组成简单 ,为书虱和长角谷盗两种 ,分别占捕获总虫量的 99.5%及 0 .5% ;8月份仓库昆虫 7种 ,主要种类是书虱和螨类 ,分别占捕获总量的 61 .9%和 38% ,次要害虫种类有赤拟谷盗、长角谷盗、玉米象、谷蠹及花斑皮蠹。不同储藏期、不同粮层、不同方向害虫分布也存在差异。调查还表明钢板仓书虱和螨类有相似的生态环境。
The distribution of pests species in steel barn and the distribution of pests, lice and mites in different parts of the storage period were investigated by using GJ89 trap. The results showed that: from March to April, the species composition of the warehouse insects was simple, which accounted for 99.5% and 0.5% of the total number of trapped insects, and 7 species of warehouse insects in August. The main species were larva And mites, accounting for 61.9% and 38% of the total catch, respectively. The main pest species are red tarragon, longhorn beetle, corn, beetle and spotted beetle. There were also differences in the distribution of pests in different storage periods, different layers and different directions. The survey also showed that steel sheet lice and mites have similar ecological environment.
