At present, there are more than 40 kinds of cotton pests, of which thrips, aphids, terrestrial tigers, lucid bugs, spider mites, cotton bollworm and cotton aphid are the most serious pests in thrips.

In recent years, in some places, attention has been paid to the protection and utilization of natural enemies, comprehensive prevention and control, effective control of cotton pests, and the application of pesticides has also been greatly reduced.
