2013―2017年河南省南亚果实蝇种群动态监测

南亚果实蝇(Zeugodacus tau(Walker)),俗称南瓜实蝇,是一种重要经济性实蝇,被河南省列为补充检疫性有害生物。本研究以诱蝇酮为引诱剂,自2013年至2017年在河南省9个地市27个监测点针对南亚果实蝇成虫开展了诱捕监测,并进行了种群动态分析。结果表明,信阳、三门峡、南阳诱到南亚果实蝇成虫较多;南亚果实蝇在河南的发生高峰期在7―9月份,与寄主植物的结实挂果期基本一致。本研究能够为河南省南亚果实蝇入侵防控工作提供科学依据。

The monitoring of population dynamics of Zeugodacus tau in Henan from 2013 to 2017

The fruit fly zeugodacus tau(Walker),commonly known as pumpkin fruit fly,is an important economic fruit fly,and is listed as a supplementary quarantine pest in Henan Province. From 2013 to2017,this study conducted trapping monitoring and population dynamics analysis of zeugodacus tau at 27 monitoring points in 9 cities of Henan Province. The results showed that Xinyang,Sanmenxia and Nanyang all induced more adult fruit flies. The peak period of zeugodacus tau in Henan Province is from July to September,which share the same period of fruit bearing and fruit setting of the host plant.This study can provide scientific basis for the invasion and control of zeugodacus tau in Henan Province.
