  • In the larval stage, the insect causes damage to crops
  • FAW has several generations per year and the moth can fly up to 100 km per night
  • FAW affects mainly maize crops, but also rice and sorghum as well as cotton and some vegetables
  • It has the potential to feed on more than 80 plant species
  • FAW infestations result in plant damage which may lead to total yield loss or reduced grain quality and quantity
  • FAW is a transboundary pest with a high potential of spreading due to bioecological and trade aspects
  • FAW was first detected in Central and Western Africa in early 2016 (Benin, Nigeria, Sao Tome and Principe, and Togo) and in late 2016 and 2017 in Angola, Botswana, Burundi, Cote d’Ivoire, Democratic Republic of Congo, Ethiopia, Ghana, Kenya, Malawi, Mozambique, Namibia, Niger, Rwanda, Sierra Leone, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe, and it is expected to go further
  • For the time being, FAW modality of introduction and its spread are only hypotheses.
