Latest Armyworm Forecast from ETOP (October 2019)


Fall Armyworm (Spodoptera frugiperda) (FAW): FAW infestations were reported in irrigated maize in Malawi and Zimbabwe and the pest is expected to have continued being a problem to rainfed and irrigated crops across invasion countries

African Armyworm (AAW) (Spodoptera exempta): AAW outbreak was not reported during this month.

Current situation

Fall armyworm (FAW)

FAW infestations were reported in irrigated maize in Masvingo and Matebeleland Provinces in Zimbabwe. Increased pheromone trap catches were reported in Malawi during October. Affected farmers are receiving material and technical support from MinAgri to control the pest. No update was received elsewhere in outbreak and invasion areas, but it is likely that the pest continued being a problem to rainfed and irrigated cereal and other susceptible crops across countries (IRLCO-CSA, OFDA/PSPM).

African Armyworm (AAW)

AAW was not reported during this month.

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 preventive interventions remain critical to abate the damage (OFDA/PSPM).

African Armyworm (AAW)

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