Abstract Fruit flies are significant insect pests, worldwide. Tephritid species diversity and their seasonal abundance were investigated over 2 yr (May 2017 to May 2019) in Western Burkina Faso. A mass trapping experiment consisting of 288TephriTrap types, operating with four types of parapheromones comprising methyl eugenol, terpinyl acetate, trimedlure, and cue lure and an insecticide (Dichlorvos), was used for attracting and killing insects. Plant formations including natural fallows, mango orchards, and agroforestry parks in each of the six study sites were selected for data collection.Twenty-nine tephritid species belonging to 10 genera were identified. Fourteen fruit fly species were identified for the first time in Burkina Faso. The genera Ceratitis MacLeay (Diptera:Tephritidae) and Dacus Fabricius (Diptera:Tephritidae) with, respectively, 14 and 7 species recorded were the most represented. The dominant species caught was the invasive Bactrocera dorsalis Hendel (Diptera: Tephritidae) followed by Ceratitis cosyraWalker (Diptera:Tephritidae) and Ceratitis silvestrii Bezzi (Diptera:Tephritidae).The fruit fly population density was very high during the rainy season, with peaks occurring in June or July.The fruit fly species were generally more abundant during the hot and rainy seasons than during the cold and dry seasons. The highest diversity was recorded in natural fallows, as compared with the mango orchards and agroforestry parks. Tephritid species found refuge in the mango orchards during the dry and cold periods.The results of that investigation may be used for developing a sustainable pest management strategy for commercial orchards.

西非布基纳法索三种植物群中果蝇（双翅目：实蝇科）的季节性丰度和多样性

摘要 果蝇是世界范围内的重要害虫。在西布基纳法索对实蝇属物种多样性及其季节性丰度进行了超过 2 年（2017 年 5 月至 2019 年 5 月）的调查。一个由 288 个 TephriTrap 类型组成的质量诱捕实验，使用四种类型的辅助信息素，包括甲基丁香酚、醋酸萜品酯、trimedlure、提示诱剂和杀虫剂（敌敌畏），用于吸引和杀死昆虫。选择了六个研究地点中的每个地点的自然休耕地、芒果园和农林业公园等植物构造进行数据收集。确定了属于 10 个属的 29 个 tephritid 物种。布基纳法索首次发现了 14 种果蝇。Ceratitis MacLeay (Diptera:Tephritidae) 和 Dacus Fabricius (Diptera:Tephritidae) 分别具有，记录的 14 和 7 种是最具代表性的。捕获的优势种是入侵的Bactrocera dorsalis Hendel（双翅目：实蝇科），其次是Ceratitis cosyraWalker（双翅目：实蝇科）和Ceratitis silvestrii Bezzi（双翅目：实蝇科）。 雨季果蝇种群密度非常高，出现高峰在 6 月或 7 月。与寒冷和干燥的季节相比，炎热和雨季的果蝇种类通常更丰富。与芒果园和农林业公园相比，自然休耕地的多样性最高。Tephritid 物种在干旱和寒冷时期在芒果园找到避难所。该调查的结果可用于为商业果园制定可持续的害虫管理策略。
