Abstract: Wine grape industry developed rapidly in Western Sichuan Plateau in recent year, but the wine grape pests occurred seriously and affected the healthy and orderly development of wine grape industry. To control the pests of wine grape in Sichuan, preliminary investigation identified that wine grape pests in Sichuan Tibetan included Plasmopara viticola, Uncinula necator, virus, short- beard mites, aphids，lygus bugs，clearwing moth, scarab beetles, longicorn beetles, bird, wasp, etc.. And the main species were P. viticola, U. necator, sparrows and wasp. Their damage characteristics were investigated. Poor ventilation and high humidity in vineyard was found to be the main cause of high incidence of P. viticola and U. necator. The control techniques such as reducing the number of pathogens in vineyard, increasing the vineyard ventilation and light, bagging, setting sweet and sour liquid trap were proposed and applied. And rational use of pesticides such as stone sulfur mixture, bordeaux mixture, difenoconazole azole and dimethomorph were proposed.
