According to reports, there are about 6,000 kinds of pests that harm crops around the world. In my country, there are more than 250 kinds of rice pests, more than 1,000 kinds of fruit tree pests, more than 50 kinds of corn pests, and more than 300 kinds of warehouse pests. Armyworms, locusts, rice borers, corn borers, cutworms, cotton aphids, wheat midges, aphids, leafhoppers, planthoppers, scale insects, etc. are all important pests.


The losses caused by pests to agricultural production are quite alarming. It is estimated that the average annual loss of crops grown in the wild is 10%, and the average loss rate of indoor storage is 5%. As far as rice pests are concerned, the loss in 1950 was more than 40 million tons. Therefore, fighting against pests and taking back food from their mouths is an extremely important measure in agricultural production.

2. The enemy of home life

There are pests in every family room to a greater or lesser extent. The pests hiding in every corner of the house do not attract your attention because they are small or in small numbers. Otherwise, as long as you check in the books or papers that have been hidden for a long time and are not frequently turned, you will see small insects crawling around. Could you please check again whether there are holes in woolen clothes that you don’t wear often? If so, there must be moths hiding in the suitcase. Even sugar that has not been eaten for a long time contains worms, which are difficult to see with the naked eye. As for insects on garden flowers and trees, they are common among everyone.
