Control Effect of Intelligent Pest Control System on Green Leafhopper in Tea Garden

In order to explore the green control technology for green leafhopper in tea garden and reduce the use of chemical pesticides, an experiment was carried out on three tea plantations in Anxi County to control the green leafhopper by Silei Intelligent Pest Control System. The results showed that after 20 days operation of the intelligent pest control system, the insect population density in the prevention and control area of Dabaofeng Tea Garden Base was 9 heads per square meter, then decreased gradually, and was lower than the control area. After 10 days operation of the intelligent pest control system, the insect population density in the prevention and control area of Lishan Chaxian Tea Garden Base was stabilized at about 5 heads per square meter, which was lower than that of the control area. There were two peaks in the control area, and the highest insect population density was 24 heads per square meter. The insect population density in the prevention and control area of Shanguo Yinyi Tea Garden Base was stable at about 8 heads per square meter, which was lower than that of the control area, and there were three peaks in the control area. The results showed that the intelligent pest control system of Silei had obvious effect on the control of green leafhopper, and was safe to tea plant and natural enemy population. It was suitable for popularization in tea gardens.
