摘要：

为了明确杞柳瘿蚊的越冬虫源和越冬场所，掌握该虫的生物学特性，为防控该虫提供科学依据，本研究通过采摘剥查当年生被杞柳瘿蚊为害的杞柳枝头上形成的虫瘿，及将采摘的虫瘿和剥查出来的杞柳瘿蚊幼虫和蛹放置在不同的环境条件下研究其越冬情况，并调查该虫的越冬场所。结果表明：杞柳瘿蚊以幼虫和蛹在当年生被害杞柳枝头上的虫瘿内越冬，越冬场所在土壤外部，越冬虫源主要来自于杞柳加工过程中残留在下脚料上的虫瘿和集中堆放的未经加工的带虫瘿柳条；其次是杞柳收割过程中散落并残留在田间的虫瘿。实际生产中，对收割后杞柳枝头上的虫瘿进行摘除并集中销毁，同时清除残留在田间的虫瘿，可有效降低杞柳瘿蚊的越冬虫源，减轻翌年杞柳瘿蚊对杞柳的危害。

Abstract:

In order to make clear the overwintering generation and the overwintering place of Rhbdophaga SP, master its biological characteristics and provide the scientific basis to control this insect, the author picked and peeled the galls in the infested wickers, then put the larva and pupa into different environmental conditions to research the characteristic of overwintering and find the overwintering place. The results showed that: the larva and pupa overwintered in the galls of damaged wickers in the current year. The overwintering place of this pest was out of soil. The overwintering generation of the pest was mainly in the galls which were in the scrap after processing and in the outside branches before processing. The galls falling in the field in harvest was the other source. In the practical application, galls must be removed and destroyed centrally after wickers harvest. And the galls falling in the field must be eliminated simultaneously. It could largely reduce the number of overwintering generation after taking such measure. And the perniciousness of Rhbdophaga SP would be remitted the next year.
