Abstract
A survey of insect- pests and beneficial –insects of faba bean and garden pea plants was conducted during the consequent growing seasons of 2014-2015 and 2015-2016 at Abis, Alex. Egypt. The identified insect- pests of faba beans foliage implied 4 species: Liriomyza trifolii (Burgess), Aphis craccivora (Koch.), Bemisia tabaci (Gennadius)and Emposca lybica(De Berg.). The highest recorded number of inspected insects was aphid, versus the lowest recorded one of E. lybica, throughout both the consequent seasons of              ( 2014-2015) and  (2015-2016). The two inspected and identified insect species on garden peas foliage were Liriomyza trifolii and Bemisia tabaci. Leafminer was recorded at highest  numbers  throughout  both the growing  seasons.   Additionally both the detected lepidopteran insects; the blue butterfly, Cosmolyce baeticus Polyommatus and bean pod borer,Etiella  zinckenella Treitschke injuriously infested faba beans and garden peas pods. Where as, C.baeticus has been registered at high numbers on faba bean pods during both the growing seasons ,versus E.zinckenella, which was relatively high of garden peas pods.  The three inspected and identified beneficial insect species on faba beans plants were Diglyphus isaea (Walker) (Or.Hymenoptera) Chrysoperla carne (Stephens) (Or. Neuroptera) & Coccinella undecimpunctate (Linnaeus) (Or.Coleoptera). The calculated numbers of parasitoids and predators on faba bean plants increased as the number of their hosts increased. The calculated number of   (Diglyphus isaea) was relatively high followed by Chrysoperla carnea and Coccinella  undecimpunctate in both the growing seasons. Two species of natural enemies were also inspected and identified on garden peas plants, ie. D. isaea and C. undecimpunctate. D. isaea was recorded as the highest number of the natural enemies, and C. undecimpunctata as the lowest number of inspected predators.
