AI Technical Summary

Technical Problem

The prior art has the problem of excessive use of chemical pesticides leading to environmental pollution and natural enemies in preventing and controlling gray tea slabs. The difficulty in collecting during pupal period in insect sterility technology affects irradiation efficiency.

Method used

X-ray sterility method is used to distinguish male and female pupae, and perform gradient treatment of different radiation doses, combined with the method of delaying the pupal period by low temperature, the acquisition efficiency of sterile insects is improved, and sterile male and female pupae are released in the tea garden to control the pest population.

Benefits of technology

Effectively reduce the fertility and population growth rate of gray tea pulp, reduce the use of chemical pesticides, improve environmental safety, and improve the sustainable management capabilities of tea garden pests.

Abstract

The invention discloses a green method for preventing and treating ectropis grisescens, and belongs to the field of crop plant protection. According to the method, sterile ectropis grisescens adults are obtained through X-ray irradiation to suppress field wild ectropis grisescens populations, so that use of chemical pesticides is reduced, and the ecological environment of a tea garden is protected. According to the method, the physiological influence of different irradiation doses on the ectropis grisescens pupas and adults is determined, the relationship between the sterility rate and the irradiation doses is established, and the optimal irradiation dose is screened out for obtaining the sterile ectropis grisescens. In addition, the invention further provides a method for delaying eclosion time of ectropis grisescens pupae at low temperature, so that centralized eclosion of sterile insects is achieved, operability of the method is enhanced, and the field release effect is optimized. Through a field release experiment, the sterile ectropis grisescens subjected to irradiation treatment can remarkably inhibit the number of insects, and it is proved that the method has a good prevention and treatment effect. Meanwhile, the quality of the tea garden fresh leaves releasing the sterile insects is remarkably improved.
