Latest Armyworm Forecast from ETOP (November 2019)


Fall Armyworm (Spodoptera frugiperda) (FAW): FAW infestations were reported in Ethiopia, eastern Kenya and Uganda and likely persisted in rainfed/irrigated areas in other countries

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

Current situation

Fall armyworm (FAW)

FAW infestations were reported in rainfed maize and other crops in several dozen districts in six administrative regions in Ethiopia during November. FAW was also reported attacking early planted maize crops in eastern Kenya and detected in several districts across maize growing regions in Uganda with an estimated average incidence of 40% and overall crop damage of <10% due to increased impacts of natural enemies, heavy rains and timely preventive interventions by affected farmers. Infestations of FAW in rainfed and irrigated crops are also likely in other countries across sub-Saharan Africa, Asia and the Pacific Regions and likely continued causing damage (DLCOEA, IRLCO-CSA, OFDA/PSPM, PPD/Ethiopia, PPD/Uganda).

African Armyworm (AAW)

AAW was not reported during this month.

Forecasts (for the next 6 weeks)

Fall armyworm (FAW)

FAW will likely continue affecting rain-fed and irrigated maize and other crops across sub-Saharan Africa, Asia, the Pacific Regions and elsewhere during the forecast period. Active monitoring, surveillance, reporting and information sharing as well as timely preventive interventions remain critical to abate major crop damage (OFDA/PSPM).

African Armyworm (AAW)

Some AAW activities may commence in southern Africa during the forecast period (OFDA/PSPM).
