Latest Armyworm Forecast from ETOP (May 2020)


Fall Armyworm (Spodoptera frugiperda) (FAW): FAW was reported in Tanzania. It is likely that the pest was present elsewhere in maize and other cereal growing areas during this month.

African Armyworm (Spodoptera exempta) (AAW): AAW outbreaks were not reported during this month.

Current situation

Fall armyworm (FAW)

Fall armyworm (FAW) was reported affecting irrigated maize in Malawi and Zimbabwe. The pest may also present in other IRLCO-CSA member-countries, but at a much lower intensity given that maize crops had matured. Other maize growing regions across Africa, Asia, Pacific and elsewhere likely experienced FAW presence (DLCO-EA, IRLCO-CSA, OFDA/PSPM).

African Armyworm (AAW)

AAW outbreaks were not reported during this month (IRLCO-CSA).

Forecasts (for the next 6 weeks)

Fall armyworm (FAW)

FAW will likely continue affecting rain-fed and irrigated maize and other cereal crops across sub-Saharan Africa, Asia, the Pacific Regions and elsewhere during the forecast period. Active monitoring, surveillance, reporting and preventative interventions remain critical to abate significant crop damage (OFDA).

African Armyworm (AAW)

AAW activities will likely remain calm in the primary outbreak areas during the forecast period (IRLCOCSA, OFDA/PSPM).
