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.
