淮南储藏物粉螨防制研究

Investigation on propagation and prevention of acaridida in storaged foods in Huainan

调查储藏物中粉螨的孳生情况以及粉螨的防治效果.对5种储藏物每两年采集一次样本,分别进行粉螨的分离、鉴定及计数,并利用统计学方法进行多样性分析.采取物理和化学方法防制粉螨.共检获粉螨15种,分别隶属于5科13属;粉螨的平均孳生密度、物种丰富度指数、物种多样性指数均呈逐年下降趋势.淮南地区储藏物中粉螨的孳生情况有所改善;对粉螨的防制取得了一定的效果.

To investigate propagation and prevention of acaridida in storaged foods. The samples of 5 kinds of storaged foods were collected every one year, and the acarid mites were separated, identified and counted respectively, then the statistics methods were used to analyze the community diversity. The physics and chemistry methods were taken to prevent and eliminate the acarid mites. 15 species of the acarid mites were found in the aggregate, belonging to 13 genera,5 families. All statistics results of the mites showed the descending trend of the average breeding density, the species richness index and the diversity index. The status of propagation of acaridida in storaged foods has been improved in Huainan villages. The prevention measures seem to take some effects.
