N2  - The incidence of the leafminer Liriomyza congesta (Becker) and Bruchus rufimanus Boh. was studied in fourteen faba bean varieties and bred lines under Maryout rainfed conditions during 2000/2001 growing season. According to the percentage of infestation, the fourteen varieties could be divided into the following groups: The first group: exhibiting the least level of infestations were recorded for Giza Blanca, FLR, Giza 461 L.149, and L.143, i.e. 31.05, 29.12, 28.00, 26.58 and 25.17% respectively. The second group: moderate infestation with the leaf miner was found for Mar.3, HBP-B, and Mar.4 were 43.65, 39.51, and 36.15%, respectively. The third group; included plants more susceptible to L. congesta infestation HBP-D, L.145, Mar2, Mar1 and HBP-C varieties where the infestation percentage were found to be 53.57, 52.61, 50.00, 49.37, and 46.85%, respectively. The fourth group: included the most susceptible plant, i.e. HBP-MSR as percentage of infestation reached 59.13%. It was noticed that leaves lower in the plant strata were found to be the most infested by the leaf miner followed by the medium level and least in the upper level for faba bean plant. Statistical analysis showed highly significant differences in the percentages of infestation of faba bean seeds by the B.ritfimanus. The results indicated that the highest infestation occurred in HBP-MSR, HBP-D, L.145 and HBO-C bred lines, where 18.43, 12.71, 11.04 and 10.38 %, respectively were recorded. Low infestations in HBP-B, Mar.4, FLR and MaL2 lines were found to be 4.85, 4.50, 4.17 and. 3.93%, respectively. The other varieties exhibited moderate infestation
