Abstract
Eight tomato varieties were investigated to evaluate the mean numbers of Bemisia tabaci adults coincident to the occurrence of TYLCV and yield. Tomato hybrids of Dora, Jakal and Facolta were the lower susceptible of B.tabaci adult infestation, while TY-20 and Sheva variety were moderately infested. The most susceptible to the insect infestation were Strain-B, Edkway, and Castle Rock varieties (Doss, 1982). TYLCV symptoms infection occurred coincident with the mean numbers of B.tabaci adult infestation (Rosset at al., 1990). Meanwhile, yield per plots (1/16 Feddan) showed the highest yield in case of the lower infection of TYLCV as well as the insect adult mean numbers, viz. Facoita, Jakal and Dora hybrids. While the lower yield was given in case of the highest infection of TYLCV and insect adult means, viz. Castle Rock, Edkawy and Strain-B.
