The spotted wing drosophila, Drosophila suzukii Matsumura, is an insect pest of soft-skinned fruit, native to Eastern Asia. Since 2008, a world-wide dispersal of D. suzukii is seen, characterized by the establishment of the pest in many Asian, American and European countries. While the potential for invasion of continental Africa by D. suzukii has been predicted, its presence has only been shown for Morocco in Northern Africa. Knowledge about a possible establishment in other parts of the continent is needed as a basis for pest management. In 2019, we carried out a first survey in three counties in Kenya to monitor for the presence of D. suzukii using traps baited with a blend of apple cider vinegar and red wine. A total of 389 D. suzukii flies were captured in a fruit farm at Nakuru county, with more female flies being trapped than males. We confirmed the morphological identification of D. suzukii using DNA barcoding. In 2020, we performed a follow-up survey at 14 locations in six counties to delimit the distribution of D. suzukii in the main berry growing zones in Kenya. The survey indicated that so far D. suzukii is restricted to Nakuru county where it was initially detected. This is the first study to provide empirical evidence of D. suzukii in continental sub-Saharan Africa, confirming that the pest is expanding its geographic range intercontinentally. Given the high dispersal potential of D. suzukii, a concerted effort to develop management strategies is a necessity for containment of the pest.

在撒哈拉以南非洲大陆发现斑点的果蝇果蝇Suzukii

斑翅果蝇Drosophila suzukii Matsumura是一种软皮水果的害虫,原产于东亚。自2008年以来,人们看到了铃木D.的全球扩散,其特征是在许多亚洲,美洲和欧洲国家建立了该害虫。虽然已经预言了铃木D.可能入侵非洲大陆,但它的存在仅在北部非洲的摩洛哥得到了证明。需要了解有关该大陆其他地区可能建立的机构的知识,以此作为有害生物管理的基础。2019年,我们在肯尼亚的三个县进行了首次调查,以使用苹果醋和红酒的诱饵诱捕的陷阱来监测铃木D. 总计389铃木蝇在纳库鲁县的一个水果农场被捕,被捕的雌蝇比雄蝇多。我们使用DNA条形码确认了铃木D.的形态学鉴定。2020年,我们在六个县的14个地点进行了一项后续调查,以划定铃木D.在肯尼亚主要浆果种植区的分布。调查表明,到目前为止,铃木D.只限于最初被发现的纳库鲁县。这是第一项为撒哈拉以南非洲大陆提供铃木D.经验证据的研究,证实了该害虫正在不断扩大其地理范围。鉴于铃木D.的高分散潜力因此,共同努力制定管理策略是控制有害生物的必要条件。
