中文摘要： 【目的】 明确宽带果实蝇Bactrocera（Zeugodacus）scutellata（Hendel）寄主种类、繁殖特征、生殖潜力等生物特性。【方法】 本文采用野外观察与室内实验方法，对宽带果实蝇繁殖生物学进行了研究。【结果】 研究表明，南瓜花是宽带果实蝇的寄主，雌虫产卵于南瓜花蕾顶端，幼虫在花蕾中自上而下取食，成熟后入土化蛹。该雌成虫成熟卵巢卵粒数量少。【结论】 研究发现，宽带果实蝇寄主范围较窄，产卵量较低，危害较为隐蔽。南瓜雄花可以作为监测和预报宽带果实蝇种群变动的关键指示物，为开展宽带果实蝇科学防控提供了不可或缺的基础信息。
英文摘要： [Objectives] To confirm the biological characteristics of Bactrocera (Zeugodacus) scutellata (Hendel), including its effects on host plants, reproductive features and potential to cause significant economic damage. [Methods] Field surveys and laboratory experiments. [Results] Pumpkins are important host plants of B. scutellata; females laid eggs on the top of pumpkin flower buds and the larvae ate the flower stamens from top to bottom before dropping to the ground. The mature ovaries of female adults contained a low number of eggs. [Conclusion] B. scutellata has a narrow range of host plants, low reproductive capacity and causes inconspicuous damage to plant crops. Male pumpkin flowers could be important indicators for monitoring this pest’s population dynamics and the resultant information could provide a scientific basis for the effective control of B. scutellata.
