摘要
通过调查、黑光灯,性信息素诱集,结果表明苹果蠹蛾(Laspeyresiapomonolla(L))幼虫越冬主要在树干30～90cm处的树皮下,裂缝中;越冬幼虫化蛹,成虫羽化始期分别在4月下旬和5月中下旬,羽化高峰在5月底6月初,越冬蛹的发育起点温度为9.4℃,有效积温为216.42日度。
In order to effectively control Laspeyresia pomonolla(L) and find out the information about its overwintering bionomics,a serious stady was made in 2001～2002. The results show that codling moth overwinters as late-developing larvae in tree trunk 30～90 cm,often hides beneath tree crevices or bark. The overwintering larvae begin to become pupae in late April. The pupae begin to emerge in the middle or late May and the peak of emergence is from late to early June. The threshold temperature of development for pupae is 9.4℃, and the effective temperature accumulated is 216.42 day-degree.
