摘　　要：【目的】近年来,世界性检疫害虫瓜实蝇由我国南部省份传入河南省西南部地区,对当地多种经济作物的产量和品质造成较大影响。明确该虫在新传入地区不同寄主作物上的种群动态,有助于揭示其在田间的发生危害规律,为当地防治工作提供科学依据。【方法】2020—2022年在河南省南阳市内乡县对田间瓜实蝇成虫开展诱捕监测,比较分析其在丝瓜、南瓜和西葫芦3种寄主作物上的种群发生动态。【结果】瓜实蝇在河南省内乡县每年均有发生,成虫种群基本发生于6~7月下旬—10月下旬,发生盛期在8月中旬—9月下旬,有一个明显发生高峰期;其种群数量、种群动态以及发生期均受寄主植物和年代的影响。【结论】河南省内乡县瓜实蝇种群数量和危害程度呈逐年加重趋势,不同瓜类作物蔬菜田中应因地制宜及时采取防治措施。【Aim】In recent years,the melon fly Zeugodacus cucuribitae(Coquillett),a worldwide quarantine pest,has been introduced from the south of China to the southwestern part of Henan province,causing a major impact on the yield and quality of a variety of cash crops.Investigating its population dynamics on different host crops in newly introduced regions helps reveal its damage pattern in the field,and provides a scientific basis for local pest management.【Method】From 2020 to 2022,the population dynamics of Z.cucuribitae adults on three host cucurbits,namely Luffa cylindrica,Cucurbita moschata,and Cucurbita pepo,were surveyed and comparatively analyzed in the fields of Neixiang County,Nanyang City,Henan Province,China.【Result】This pest occurred in all three years in Neixiang county,with adult populations occurring between late June to July and late October,and the peak period of adults occurring from mid-August to late September.Its population size,population dynamics,and period of occurrence were all affected by the host crops and the age.【Conclusion】The population size and damage of Z.cucuribitae in this region are increasing year by year,and control measures should be taken timely in different melon crops according to local conditions.
