Abstract

Sweet potato (Ipomoea batatas (L.) Lam) is an important staple food and commercial crop in central
Tanzania and most of the tropical countries. The on-farm crop productivity in the country is low estimated at 9.5 t
ha-1 . Of this, the proportion of marketable yield is even lower due to substantial damages inflicted by the sweet
potato weevils, the Cylas spp. A study was conducted to establish the pest status and distribution of weevils in
Gairo and Ikungi districts of central Tanzania.
