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。 Peach mungbean beet is one of the common borer pests in northern China. It is also a major pest of fruit trees in apple, sago, pear and mountain plants in Changchun. The insects occurred in Changchun area for most of one year, and a few early larvae could complete two generations. To mature larvae in the topsoil knot flat oval wintering. Based on the clear rules of its occurrence and the previous community efficacy tests, it is a feasible and predictive method to monitor the occurrence and occurrence of male moths with sex attractants to guide the chemical control. In the moth peak 3 ~ 5d after spraying the tree control, which can effectively control the damage.
