Description Eight local long-duration landraces from Kitgum and Gulu in Uganda were grown at Kabete during 1998-99. Insect pest and damage assessments were conducted at pod maturity. The insect pests that caused damage on the pigeon pea (Cajanus cajan) lines were pod fly (Melanagromyza chalcosoma), pod borers (Etiella zinckenella, Lampides sp. and Helicoverpa armigera) and pod-sucking bugs (Clavigralla tomentosicollis). In general, total seed damage was low and the percentage damage by pod fly was 2-7%. Pod fly accounted for 80% of the total seed damage, pod borers 12.7% and pod-sucking bugs 6.3%. ICEAP lines 00954, 00955, 00956 and 00957 had relatively higher levels of damage than the other lines. ICEAP 00953 and 00958 appeared more tolerant of pod fly.
