| 中文摘要: |
| 利用田间剖解坑道和漏斗式诱捕器研究了葡萄树光滑足距小蠹的生活史和季节性飞行活动规律。结果表明，该小蠹在成都地区1年发生3~4代，具有局部世代现象，自11月始以雌成虫在主干基部的坑道中群集越冬。越冬雌成虫于第2年3月开始出孔飞行，全年雌成虫有2个飞行活动高峰，其中越冬代雌成虫的飞行活动为最高峰。 |
| 英文摘要: |
| The life history and seasonal flight activity of Xylosandrus germanus attacking grapevine were studied by dissection of galleries and Lingren's traps in fields. The results showed that it had 3-4 generations per year with partial generations, and overwintered as adult females clustering in the galleries of bole base of grapvines from November. The overwintering females began to come out of galleries and fly in March of the next year. There were two peaks of flight activity in a year, and the overwintering females’ flight activity was higher. |
