Morphological characteristics and living habits can be found in the cotton pest - small green leafhopper.

Prevention and control methods (1) Before the adult insects hibernate, timely scrape off the curled skin, remove fallen leaves and weeds, and reduce the source of overwintering insects. (2) After the overwintering adults migrate to tea gardens, timely spray 40% chlorpyrifos emulsion 1500 times or 35% chlorpyrifos emulsion 2000-3000 times, 2.5% Uranus emulsion 4000 times, 1.8% Nongjiale emulsion (avermectin B1) 3000-4000 times, 20% Yechan powder (chlorpyrifos) emulsion 800 times, 25% sumidine wettable powder 600-800 times, 20% chlorpyrifos emulsion 400 times, 50% malathion emulsion 1500-2000 times, 10% imidacloprid wettable powder 2000 times, 2.5% Dichlor 2.5% Kungfu emulsion during the peak hatching period of each generation of nymphs. Oil and 50% anti aphid super wettable powder with a concentration of 3000-4000 times can achieve good results. (3) Using 50% methamidophos and 40% omethoate to clear tea gardens in winter can greatly reduce the overwintering population of small green leafhoppers. If thoroughly controlled, the peak period of tea small green leafhoppers in the following year can be postponed to after June 20th.
