It is suggested to use pesticides such as diflubenzuron, emamectin benzoate, Bacillus thuringiensis, tetrachloroacetamide, chlorantraniliprole, indoxacarb, flubendiamide, beta-cypermethrin, tebufenozide, fluoroamide, fenpropathrin, etc., and attention should be paid to the appropriate control period. Alternate use reduces the drug resistance of pests and prolongs the service life of pesticides.
