Abstract
Field pea Pisum sativum L. is an important legume crop in Ethiopia and insect pests are the major constraints in its production. Amongst these pea weevil Bruchus pisorum L. is important. This study evaluates the effects of lambda cyhalothrin (Karate 50EC), chlorantraniliprole (Coragen 200SC) and carbaryl (Sevin 85WP) under field conditions at the Holetta Agricultural Research Center, Ethiopia. The insecticides were applied at flowering, pod setting and both at flowering and pod setting stages, using the susceptible variety ‘Burkitu’ in randomized complete block design. The results revealed that there was no significant difference among the treatments. Similarly, insecticide application frequency and crop phenology had no effect on the incidence of egg and larvae in field, and on adult emergence under storage conditions.
