Abstract
The granary weevil, Sitophilus granarius l. was reared on local maize varieties which cleaned from any insect infestation under laboratory condition with temp. 30±2°C and 65 ±5% relative humidity. The obtained results revealed that, under non-choice test method the maize variety S.c.173 was the most favorable variety and presented by 26.4 ±0.87 and 31.4 ±20.87 indiv. followed by T.W.C. 324 which presented 22.2±0.86 and 26.8±1.02 indiv. for F1 and F2 progeny, respectively. On the other hand, under free-choice test method also the maize variety S.C.173 recorded the most attracted variety and the highest mean emerged insect adults for the F1 progeny or F2 progeny and presented by 29.60 ±1.17 and 33.80 ±1.77 indiv., respectively. Moreover, the maize variety T.W.C. 324 came in the second category and presented by 25.20 ±0.97 indiv. for F1 and F2 progeny, respectively. Also, the maize variety S.C.173 had the highest percentage of weight loss after four weeks and eight weeks and presented by 2.40 and 3.70 %, respectively.
