The key application technology for sex pheromone of Grapholitha molesta was studied from the aspects of different hanging heights and orientations,different doses and types of traps through the tests on trapping quantity of G. molesta in fields. The results showed that the trapping effect was enhanced when the hanging height was increased,and the trapping effect was the best in west direction. The trapping effect was enhanced when the dosage was increased. When it was up to 6 lures,the trapping effect was the best with 38. 75 head / trap; the next was 2 lures with 31. 00 head / trap. All types of traps had trapping ability to G. molesta,among which triangle trapper was the best,followed by self-made bottle trap. Their trapping effects were 138. 75 and 100. 25 head / trap,respectively.
