The result showed that the high preference of the white fly insect was found on the Fasami variety fllowed by Malaci,Bambawi , Zytoni and Tufahi which the population density of lnsect on the bellow Surface of the leaves was 83.97,21.53,8.67,0.02,0.02 nymph/50 cm² respectively. Hartha region had the highest population density that reach to 46.18 nymph/50 cm² while Zubair region had the lowest population density that reach to 4.48 nymph/50 cm². The percentage of infection on different Jujube varieties showed that the highest infection rate was 41.71% in Fasami variety while the lowest was 3.19 in Tofahi variety.Also the highest infaction rate was 24.78 recorded in Hartha region where as the lowest was 10.38% recorded in Zubair region.
