Abstract

Armyworm reports and weather records for eastern Africa were analysed for armyworm seasons from 1972-88. Relationships between the frequency and distribution of outbreaks and weather (especially wind and rainfall) were summarized for each season separately and compared between seasons. The work reported in this bulletin will enable armyworm forecasters in eastern Africa to compare present and past seasons, predict how seasons might develop, and improve forecasts. The results are being used to assess the economic viability of strategic control.
