我国粮食产后流通环节损失较大,仅害虫造成的损失就高达农村储粮的8%~10%,所以杀虫剂的应用一直是防治储粮害虫的主要方法。然而由于杀虫剂的大量使用,给储粮品质和生态环境造成较大影响,同时,使储粮害虫的抗性逐渐增强。而植物性杀虫剂的应用有望解决这些问题。本试验用有机溶
The post-partum grain circulation losses in our country are relatively large. The losses caused by pests alone are as high as 8% -10% of the stored grain in rural areas. Therefore, the application of insecticides has been the main method for preventing and controlling stored grain pests. However, due to the large-scale use of pesticides, the grain quality and ecological environment have a greater impact, at the same time, the resistance of stored grain pests is gradually increased. The application of plant insecticides is expected to solve these problems. This test with organic solvents
