采用田间性诱芯诱蛾、虫果调查以及自然变温条件下越冬幼虫出土和成虫羽化观察相结合等方法，研究了桃蛀果蛾ＣａｒｐｏｓｉｎａｓａｓａｋｉＭａｔｓｕｍｕｒａ在陕西秦岭山区杏树Ｐｒｕｎｕｓａｒｍｅｎｉａｃａ上的发生规律和危害情况。结果表明，桃蛀果蛾在杏园一年发生１代，以老熟幼虫在土中结圆茧滞育越冬。越冬幼虫４月中旬开始出土，４月中旬末至４月下旬为出土盛期；成虫于５月上旬始见，５月中旬达到羽化盛期；老熟幼虫于６月１０日前后开始脱果，６月中旬为脱果高峰。幼虫老熟脱果后，在土中结圆茧进入滞育状态越夏、越冬。 The occurrence and damage of Carposinasasaki Matsumura in Prunusarmeniaca, an almond tree in the Qinling Mountains of Shaanxi Province, were studied by field-induced entrapment of moths, investigation of fruitworms and observation of emergence of overwintering larvae and emergence of adults under natural temperature conditions. The results showed that the peach moths in the apricot garden occurred a generation a year, with mature larvae in the soil cocoon formation of winter diapause. Overwintering larvae began unearthed in mid-April, from late April to late April for the unearthed period; adults in early May saw it in mid-May to reach plumage; mature larvae began to off before June 10, In mid-June off the peak fruit. Larvae mature off fruit, the cocoon in the soil into the diapause late summer, wintering.
