Abstract:: Using oriental fruit moth as test material，the release rules of male oriental fruit moth，the hazard characteristics of larvae and the relationship with temperature and rainfall were investigated and analyzed in Dalian area.The male oriental fruit moth was survey by using the traps with sex pheromone，at the same time，the field fold shoot rate，fruit decay rate and recorded about the local meteorological data were investigated and recorded.The results showed that oriental fruit moth occured 5 generations of one year including overwintering generation in Dalian area.In each generation，overwintering generation damage in peach shoots，the first generation damaged in shoots and fruits of peach and of larvae，the second generation major damaged in the early maturing varieties and peach shoots，the third generation mainly damaged in the late maturing varieties hardly damaged in peach shoots；the temperature and precipitation had much more impact on the growth，development，survival and reproduction of oriental fruit moth.
