Fall Armyworm / Stem Borers

Fall armyworm (Spodoptera frugiperda) is a common pest in the Western Hemisphere affecting many commercial crops, most importantly maize. This voracious Lepidoptera (grouping of insects that includes butterflies and moths) was first detected in Central and Western Africa in 2016 and has quickly spread throughout the continent. Fall armyworms thrive in tropical and sub-tropical climates but also spread to colder areas after overwintering in areas without severe freezes. Adult moths spread quickly via strong winds (Capinera 2005). 

Thousands of hectares of cropland have been affected in Togo, Nigeria, Ghana, Malawi, Zambia, Namibia, Mozambique, Uganda, Zimbabwe, and Western Kenya and Tanzania (Organic Farmer 2017). Field corn and sweet corn account for most of the economically significant losses, but sorghum, cotton, millet, peanut, rice, soybean, sugarcane, and wheat are susceptible, thus affecting both incomes and food security. The situation is so dire for smallholder farmers in Malawi that President Mutharika declared a state of disaster and mobilized government agencies to assist farmers and subsidize pesticides. Crops in Malawi most affected are maize, sorghum, and millet (Mumbere and Mtuwa 2017). 

  1. Smallholder management of fall armyworm

    2024-11-13 The overwhelming majority of global maize farmers are smallholders, usually producing less than two acres of maize to feed their families. However, most global maize production technology has been made for large-scale farmers who grow their maize for international markets where maize is used for...
