New pest threatens crops in West Africa

The moth Spodoptera frugiperda, commonly known as fall armyworm moth, was first registered in Africa in 2016. It is not certain how it arrived, but DNA-analyses show that it is likely to have been more than an introduction. The species is a native of Latin America where it is a well-known pest. It can attack more than 80 different plant species, including important crops such as maize, rice, sugarcane, sorghum, grains and other plants in the grass family.
