Latest Armyworm Forecast from ETOP (July 2020)

Synopsis

Fall Armyworm (Spodoptera frugiperda) (FAW): FAW was reported in Tanzania, Malawi, Zambia and Zimbabwe. It may have also persisted in other maize growing countries in Asia and elsewhere.

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

Current situation

Fall armyworm (FAW)

Infestations continued in Malawi, Zambia and Zimbabwe. Although updates were not available at the time this Bulletin was compiled, it is likely that FAW persisted across the Yangtze River and further spread to the central China and perhaps Henan Province. It is to be recalled that this year the pest movement to Northern China occurred at least three months earlier than last year, suggesting the likelihood of FAW becoming a resident pest in China’s largest (45%) maize producing region. Other maize growing regions across Asia, Pacific and elsewhere likely experienced FAW presence during July (BHA/TPQ, DLCO-EA, IRLCO-CSA, USDA/FAS/GAIN).

African Armyworm (AAW)

AAW outbreaks were not reported during this month (IRLCO-CSA).

Forecasts (for the next 6 weeks)

Fall armyworm (FAW)

FAW will likely 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.

African Armyworm (AAW)

AAW activities will likely remain calm in the primary outbreak areas during the forecast period (IRLCO-CSA, BHA/TPQ).
