Tomato (Solanum lycopersicum L.) is an important vegetable crop for income, food and nutrition in Africa. Production of the crop is currently threatened by leaf miner [Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)]. Heavy infestation by T. absoluta has been reported to cause yield losses ranging from 80-100%. Tuta absoluta has high rate of reproduction and short life cycle making it very dominant in the infested tomato fields. Insecticide application for control of the pest is uneconomical for subsistence farming and beyond the earnings of majority of resource-poor farmers in Africa. Use of host resistance and or integrated pest management (IPM) strategies is slightly or not in use thus making the pest reign in the majority of African countries. This review discusses how T. absoluta threatens production and recommends some focal areas towards addressing this pest problem in the tomato industry in Africa.
