In Western Burkina Faso, the host range of fruit flies was evaluated in three plant formations between May 2017 and April 2019. Samples of 61 potential hosts were collected and incubated for fruit fly emergence. Twenty-seven hosts including cultivated and wild fruit were identified. Among cultivated fruit species, mango, and guava were the most infested while high infestation incidences were observed in the fruit of the indigenous plants Vitellaria paradoxa, Annona senegalensis, Sarcocephalus latifolius, and Saba senegalensis. Low infestation rates were observed in Anacardium occidentale, Citrus species, Opilia celtidifolia, and Cissus populnea. The highest infestation index (1648.57 flies kg−1) was observed from V. paradoxa. Eleven new host fruit infested with many fruit fly species are reported in Burkina Faso. A total of 18 fruit fly species were reared; Bactrocera dorsalis (42.94%), Ceratitis cosyra (29.93%), and Ceratitis silvestrii (22.33%) dominated those that emerged. Four fruit fly species have been detected for the first time in Burkina Faso. The main suitable fruit hosts are abundant and available from May through August during the rainy season and become rare and have low infestation from November to April during the dry season. This is the first study of its kind in the region. This study shows that the three plant formations had an impact on population dynamics of the three tephritid species of economic importance in Western Burkina Faso. This information should be integrated into the development of a fruit fly pests management strategy.

布基纳法索西部三种植物群落的寄主范围和物种多样性

在布基纳法索西部，在 2017 年 5 月至 2019 年 4 月期间，对三种植物形态中的果蝇寄主范围进行了评估。收集了 61 种潜在寄主的样本并为果蝇出苗进行了培养。鉴定了包括栽培水果和野生水果在内的 27 个寄主。在栽培的水果品种中，芒果和番石榴是最受感染的，而本土植物的果实中则观察到高感染率奇异果,番荔枝,阔叶石首， 和塞内加尔沙巴. 低侵染率观察到西洋漆树,柑橘物种，天竺葵， 和白杨. 最高侵染指数（1648.57 苍蝇公斤）-1) 观察到五、悖论. 据报道，布基纳法索有 11 种新的寄主果实被许多果蝇物种侵染。共养殖果蝇18种；背实蝇(42.94%),鼠尾草(29.93%)，以及角斑病（22.33%）主导了新兴市场。布基纳法索首次检测到四种果蝇。主要适宜的果实寄主丰富，5-8 月雨季可获得，11-4 月旱季变得稀少且侵染率低。这是该地区首次开展此类研究。这项研究表明，这三种植物形态对布基纳法索西部具有经济重要性的三种 tephritid 物种的种群动态产生了影响。应将这些信息纳入果蝇害虫管理战略的制定中。
