In Tanzania FAW outbreaks were reported in Morogoro and Iringa regions. Control operations were carried out by affected farmers with material and technical support from MinAgrsi. In Kenya, Mozambique and Zambia, limited infestations are expected on late planted maize and other cereal crops. The pest is also expected to have continued affecting maize and other crops that are at vulnerable stages in several regions.

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 preventive interventions remain critical to abate significant crop damage (OFDA).

African Armyworm (AAW)

AAW activities will likely continue in the southern outbreak region and likely appear in the eastern outbreak zone during the forecast period (IRLCOCSA, OFDA/PSPM).
