摘要

Following the arrival of Tuta absoluta Meyrick in the eastern African subregion in 2012, several studies have shown numerous ecological aspects of its invasion. We investigated the impact of T. absoluta on people's livelihoods across four counties of Kenya. Here, 200 farmers in the country were interviewed in person using semistructured questionnaires. In addition to livelihood surveys, T. absoluta distribution was mapped between 2016 and 2018 to determine its current distribution across four countries (Kenya, Sudan, Tanzania, and Uganda) in the subregion. Albeit a recent invader, T. absoluta is abundant and distributed throughout the subregion and is viewed as the worst invasive alien species of agriculturally sustainable livelihoods by tomato farmers. The arrival of T. absoluta in the subregion has resulted in livelihood losses and increased both the cost of tomato production and frequency of pesticide application. We recommend the implementation of biological control along, with other control measures in an integrated approach, against T. absoluta in the subregion, where its impact on sustainable livelihoods is serious and long-term control strategies are required to curb its detrimental effects.

Absoluta分布于2016年至2018年间映射，以确定其四个国家（肯尼亚，苏丹，坦桑尼亚和乌干达）的当前分布。尽管最近的入侵者，T. Absoluta在整个次区域中都有丰富和分布，被番茄农民被番茄农民所审视的农业可持续生计最糟糕的入侵外来物种。 T. Absoluta在次区域的到来导致了生计损失，并增加了番茄生产和农药应用频率的成本。我们建议在综合方法中实施生物控制，以综合方法，对抗次区域的核心措施，其对可持续生计的影响是严重的，并且需要长期控制策略来抑制其有害影响。
