  1. In Western Burkina Faso, fruit flies (Diptera: Tephritidae) cause economic impacts. Damage on a mango can reach 100% in late varieties, and on shea fruits, the average attack rate is 66.5%. Parasitoids offer natural biocontrol services, but the potential for this in Burkina Faso remains unknown.
  2. We performed a survey (2017–2019) in three plant formations (natural fallows n = 6; agroforestry parks n = 6 and mango orchards n = 6) to determine the levels of parasitism of tephritid fruit fly pests. For this purpose, fruits from cultivated and wild fruit fly host plant species were sampled in these plant formations and incubated for insects' emergence.
  3. In total, 1822 adults belonging to 7 parasitoid species were found. Fopius caudatus (Szépligeti) and Psyttalia concolor (Szépligeti) with 51.47% and 30.60% of the total of parasitoid adults emerged, respectively, were the most predominant. Parasitism rate varied according to host fruit species. Pupae recorded from Sarcocephalus latifolius and Vitellaria paradoxa were most parasitized (27.22% ± 3.96%) and (17.08% ± 2.37%), respectively, while those obtained from mangoes were the less parasitized (3.73% ± 0.91%).
  4. Mass rearing of F. caudatus and P. concolor, as well as habitat management, will contribute to the promotion of both, augmentation and conservation biological control.

西非布基纳法索西部三种植物形态中与果蝇相关的原生膜翅目寄生蜂及生物防治前景

  1. 在布基纳法索西部,果蝇(双翅目:实蝇科)会造成经济影响。晚熟品种对芒果的伤害可达到100%,对乳木果的平均受害率为66.5%。寄生蜂提供天然的生物防治服务,但在布基纳法索这方面的潜力仍然未知。
  2. 我们对三种植物群(自然休耕n  = 6;农林业公园n  = 6 和芒果园n  = 6)进行了一项调查(2017-2019 年),以确定实蝇害虫的寄生水平。为此目的,在这些植物结构中对来自栽培和野生果蝇寄主植物物种的果实进行取样,并为昆虫的出现进行孵化。
  3. 共发现 1822 只成虫,分属 7 种寄生蜂。Fopius caudatus (Szépligeti) 和Psyttalia concolor (Szépligeti) 分别占寄生蜂成虫总数的 51.47% 和 30.60%,占优势。寄生率因寄主果实种类而异。从Sarcocephalus latifoliusVitellaria paradoxa记录的蛹分别被寄生最多(27.22% ± 3.96%)和(17.08% ± 2.37%),而从芒果中获得的蛹被寄生较少(3.73% ± 0.91%)。
  4. F. caudatusP. concolor 的大规模饲养以及栖息地管理将有助于促进增强和保护生物控制。
