Latest Armyworm Forecast (June 2021)


Fall Armyworm(FAW) (Spodoptera frugiperda): FAW attacks were reported in irrigated maize in Kenya, Malawi, Tanzania, and Zambia. A similar situation is expected in other maize growing regions across countries and regions.

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

Current situation

Fall armyworm (FAW)

FAW outbreaks were reported in Bungoma, West Pokot, Kiambu, Uasin Gishu, Kirinyaga and Nakuru Counties, Kenya. The pest was also detected attacking irrigated maize in Midlands’s province in Zimbabwe during June. In Tanzania, moderate infestations were reported in Mara, Mwanza, Manyara, Kilimanjaro, Arusha and Tanga as well as in Malawi and Zambia where it was reported attacking irrigated maize crops. Control operations were carried out by the affected farmers with technical and material support from respective Ministries of Agriculture. FAW impact is likely in irrigated and/or rainfed maize crops across regions where awareness among rural communities is low to lacking, more so in areas where CBFAMFEW I or similar interventions did not sufficiently penetrate, and the compounding effects of the absence of sufficient resources undermined (BHA/TPQ, IRLCO-CSA, PHS/Tanzania).

African Armyworm (AAW)

AAW was not reported during this month (BHA/TPQ, IRLCO-CSA).

Forecasts (for the next 6 weeks)

Fall armyworm (FAW)

FAW is likely to continue affecting rain-fed and/or 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 timely actions remain critical to abate any major crop damage (BHA/TPQ).

African Armyworm (AAW)

Significant presence of AAW is not likely during the forecast period (BHA/TPQ, IRLCO-CSA).
