Biology, Distribution and Management of Fall Army Worm <i>Spodoptera frugiperda</i> (J E Smith) in Ethiopia

Fall army worm Spodoptera frugiperda (J E Smith) is a destructive insect pest that is native to tropical and subtropical regions of the Americas and later reported in Africa in 2016. The pest was first detected in Ethiopia in March 2017 and is likely to spread in the country. It is one of the most devastating pests in terms of crop loss and economic impact in developing countries like Ethiopia. It is a voracious pest that can cause significant yield loss. The most preferable host of S. frugiperda is maize and it causes serious damage by feeding on the ears of maize. Prevention of introduction, control, or eradication of S. frugiperda with appropriate measures is important. The IPM is one of the most preferred as complete elimination is not possible. There is a need to develop flexible, coordinated, and effective IPM approach combining various control measures including host plant resistance, mechanical, botanical, biological methods, cultural methods, and suitable doses of pesticides. This study generates information towards these ends.
