2013~2014年松针小卷蛾在承德地区首次大面积较严重发生,且有扩散和蔓延趋势。经2015~2016年的观察研究,比较系统、准确地掌握了松针小卷蛾在河北围场县和木兰林管局范围内的生物学习性:4月中旬开始化蛹,7月中旬蛹期结束,成虫4月中旬开始羽化,5~6月为盛期,7月下旬为末期,多在6~8时羽化,成虫在傍晚前后活动最盛,成虫趋光性不强,寿命8~12d;卵在5月下旬始见于针叶上,少数产在嫩枝上,卵期直至7月中旬结束;幼虫5月下旬开始出现,直到10月下旬仍可见,6~9月为幼虫单叶危害期,9月下旬~10月为幼虫缀叶危害期。越冬幼虫从10月中旬开始下树做土茧,越冬至翌年4月上旬。4月中旬开始化蛹,开启新一轮生活周期。
In 2013 ~ 2014, the pine needles moths occurred for the first time in Chengde area for the first time, with a serious tendency of spreading and spreading. After observing from 2015 to 2016, we systematically and accurately grasped the biological behavior of Pinctureae in the range of Weichang County and Mulan, Hebei Province: pupation started in mid-April, pupal stage ended in mid-July, The adults started to emerge in mid April and reached their peak from May to June. The end of July was the end of the season. The females emerged more in the period of 6 to 8, and the adults had the highest activity before and after the evening. The adult phototaxis was not strong and had a lifespan of 8-12 days. Late in the first seen in the needle, a few produced in the shoots, the egg until the end of mid-July; larvae began to appear in late May until the end of October can still be seen, 6-9 months for the larvae single-leaf hazard period, late September ~ October for the larvae decorated leaf damage period. Overwintering larvae begin to make soil under the tree from mid-October through the winter to early April the following year. Mid-April began to pupate, open a new round of life cycle.
