摘　　要：桃小食心虫是我国北方常见的蛀果害虫之一，也是长春地区苹果、沙果、梨、山植等果树的主要害虫。该虫在长春地区１年大多发生１代，少数脱果早的幼虫继续发育可完成２代。以老熟幼虫在表土下结扁圆形冬茧越冬。在明确其发生规律和在以往小区药效试验的基础上，用性诱剂监测雄蛾发生期和发生量，用来指导化学防治，是一项切实可行的预测预报方法。即在蛾峰后３～５ｄ内树上喷药防治，可有效地控制其为害。The peach fruit moth(Carpsina niponensis WalSingham) is one common borer fruit pest. It is major pest of fruit tree. The most of them has one generation, the first perfeCt one or the second imperfect in Changchun the overwinters with matur cocooned under the suface of the soil on the basis of makedifinote, It s law of occurrence and experiment on insecticidal effect the use of sex pheromone for monitoring the time and number of male peach fruit moth for directed the chemical control. this is a feasible the predicting method to wit after 3～5day Peak of moth to trees with full coverage sprat can be effective measure to control for the damage. The results showed that the method of prediction and Control has been current merits spred.
