Abstract

Faba bean plants are attacked by leguminous aphid, Aphis cracci­vora (Koch.) and jassids, Empoasca app. in the field causing severe inju­ry. Therefore, some faba bean varieties (Giza 402, Giza 3, Giza 461 and Giza Blanca) and three breeding lines (714, 716/1024 and 716/1039) were evaluated for their susceptibility to infestation with the two men­tioned insects at the farm of Sakha Agric. Res. Station during the grow­ing season of 1991/92 in an attempt to seek for less susceptible varie­ties to these insects. The obtained results showed that the population of aphids was higher than jassids on all the tested varieties and breeding lines of faba bean. Out of seven faba bean varieties and breeding lines, Giza 3 proved to be the highest susceptible to aphid infestation. Regarding the infesta­tion with jassids, Giza 3 and Giza 402 were the most infested. On the other hand, the lowest variety in susceptibility for aphids and jassids was Blanca. So, it can be recommended for cultivation at Kafr El-Sheikh Gov­ernorate as agricultural method in the integrated control programme on faba bean.
