Latest Armyworm Forecast from ETOP (September 2020)
Synopsis
Fall Armyworm (Spodoptera frugiperda) (FAW): FAW was reported in Tanzania and it is likely that the pest was present in other maize growing countries.
African Armyworm (AAW) (Spodoptera exempta): AAW outbreak was not reported during this month.
Current situation
Fall armyworm (FAW)
FAW infestation was reported in irrigated maize in Arusha and Kilimanjaro regions in Tanzania. Updates were not available from other regions at the time this Bulletin was compiled, but it is likely the pest persisted across maize, sorghum and perhaps rice growing areas in Africa, Asia, including China and other regions (BHA/TPQ, PHS/Tanzania, USDA/FAS).
African Armyworm (AAW)
AAW outbreaks were not reported during this month (DLCO-EA, PHS/Tanzania).
Forecasts (for the next 6 weeks)
Fall armyworm (FAW)
FAW will 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. Given its early appearance in some regions, example, northern China, etc. it is likely that FAW has become a resident pest in several places.
African Armyworm (AAW)
AAW activities may commence in the northern and eastern outbreak regions in southcentral Africa following the seasonal rains (BHA/TPQ).
