Abstract: In order to research the control effect and reasonable using density by sex pheromoneisotropic vector of Grapholitha molesta, using the technology the control test was carried outin peach orchard. The results showed that better control effect were 450, 600 and 990 pieces/hm2 treatment respectively, height density treatment was better. Broken end rate and borer fruit rate of Grapholitha molesta were lower than the control, control effect of broken end rate of 450, 600 and 990 pieces/hm2 treatment were 94.79%,96.58% and 96.90%, respectively, and control effect borer fruit rate were 92.55%,96.09% and 97.51%, respectively. Environmental concentration of sex pheromone was 600 pieces/hm2 to be reasonable from considering the comprehensive prevention effect and cost.

Key words: sex pheromone, isotropic method, peach orchard, Grapholitha molesta(Busck), control effect
