Tomato leafminer (Tuta absoluta): impacts and coping strategies for Africa.

Abstract

This evidence note aims to provide evidence and recommendations for decision makers in Africa responsible for the response to tomato leafminer (Tuta absoluta), as well as for external organizations seeking to assist in management. This information will be useful for decision makers to prioritize investment and interventions in responding to the continuing threat. This evidence note is structured into 5 sections. Section 1 briefly reviews tomato production trends, the T. absoluta problem, current distribution of the pest, and its environmental suitability. In Section 2, the results of farmer surveys conducted in Kenya and Zambia in 2018 were synthesized, highlighting how farmers are coping with the pest; using loss data, national tomato yield losses for selected countries were extrapolated. In Section 3, information on control methods currently deployed for the management of T. absoluta were provided, highlighting significant new findings. In Section 4, the communication aspects related to T. absoluta control, and the criteria for advice that should be given to the farmer were highlighted. Lastly, Section 5 concluded with some recommendations for key stakeholder groups.
