Symptomatic leaf samples were collected from bean fields cultivated in different governorates and tested by PCR using Geminivirus degenerate primers and Squash Leaf Curl Virus (SLCV) specific primers. All bean varieties grown in surveyed fields were found susceptible to Geminivirus infection and the dominant Geminivirus affecting bean plants was SLCV. Percentage of infection was higher at Nili season than that at the Summer season. Squash leaf curl virus (SLCV) was isolated from naturally infected common bean plants grown in Egypt and transmitted from naturally infected common bean onto twenty two species and varieties belonging to six different families i.e. Moraceae, Solanaeae, Cucurbitaceae, Fabaceae, Chenopodiaceae, and Malvaceae using viruliferous whitefly (Bemisia tabaci)
