Abstract
The population density and relative susceptibility of cucumber, Cucumis sativis L. (var., Kotia, Passandra, Nile and Asna) and common bean, Phaseolus vulgaris L. (var., Novax, Kentackey Wonder and A Slin Wonder) to infestation with the whitefly, Bemisia tabaci (Genn.) and the leafhopper, Empoasca decipiens (Paoli) under greenhouse conditions, were studied at the Experimental Research Center, El-Minia University during 2007 and 2008 growing seasons.  The average numbers of B. tabaci (nymph) was higher on cucumber and common bean varieties than E. decipiens through the two successive seasons.  The cucumber variety Katia harboured, higher numbers of the pests followed by Nile, Passandra and Asna. Common bean varieties showed a significant difference in infestation by the two pests, Novax var., harboured higher numbers in infestation followed by A Slin Wonder and Kentackey Wonder, through the two seasons.  The peak of abundance of whitefly and leafhopper occurred in April on cucumber and common bean varieties in both seasons of 2007 and 2008.  The population densities of the two insect pests on vegetable crops were higher in 2007 than in 2008. Cucumber varieties counted a higher numbers of whitefly than common bean varieties. On contrast common bean varieties harboured higher numbers of leafhopper than cucumber varieties.
