Kenya could lose half of its maize crop and face a massive food crisis following an invasion of the Fall armyworm. Although the ministry of Agriculture has no reliable data on the extent of the infestation and the impact it will have on food, the US Agency for International Development (USAid) estimates that up to 50 per cent of the maize crop could be destroyed. The pest also attacks millet, sorghum, cotton and sugar. Kenya and other African countries provided the ideal climate for the spread of the Fall armyworm because of the absence of frost.
