Abstract
Eco-friendly management of bruchid beetle, Callosobruchus chinensis infesting faba bean (Vicia faba) and cowpea (Vigna angulculata) under laboratory conditions were conducted at Department of Plant Protection, Hamelmalo Agricultural College, Keren, Eritrea, to evaluate the effectiveness of four environment friendly treatments, that is, sesame oil, neem seed powder, hot water salt solution and cold water salt solution were applied to faba bean and cowpea seeds. The lowest percent grain damage by C. chinensis was recorded in cold water salt solution for cowpea (18.7%) followed by faba beans (56.7%) compared with control treatments (62.1% in cowpea and 65.3% in faba beans). However, the sesame oil, neem seed powder and hot water salt solution are significantly (P =0.05) affecting damage of bruchid beetle in both, faba bean and cowpea. The maximum percent weight loss was found in control and cold water salt solution in comparison to other treatment.
Key words: Bruchid beetle, faba bean, cowpea, neem seed powder, sesame oil, Eritrea.
