Assessment of Different Broad Beans Varieties to the Infestation by faba bean beetle Bruchidius incarnatus (Boh.) (Coleoptera, Bruchidae) in the Store.

Abstract

This research was carried out to study the susceptibility of four varieties of faba bean (Turki “super”, Selaim, Habashi and Agbat) to Bruchidius incarnatus in the store in Khartoum region. The seeds were sub merged for three minutes in hot water 80°C, to get rid of any internal infestation. The seeds were then dried and transferred to plastic containers each contained 0.51b (233.5gm) of seeds. Four replicates were prepared with each variety. Three female adults were introduced into each container, then closed and kept in room temperature of about 20-25°C in the lab. The varieties were compared for the following: First to the number of eggs laid on the different varieties and secondly to count the number of emergence holes. Finally the number of emerging adults were also counted in a random sample of 18.0gm in each replicate. The results showed that there is no significant difference and the variety with the least infestation by B. incarnatus was Turki (super) followed by Selaim then Habashi and finally Agbat in the number of adults and Habashi is the best in egg laying.
