Abstract
Whitefly is one of the major yield reducing insect pests of soybean in the Mediterranean region. This
study was conducted to screen soybean cultivars, taken from germplasm centers and private seed
companies (USA), against the whitefly in the Mediterranean region after wheat harvest in between 1976
and 2005. No artificial infestation was made since whiteflies were very abundant. The whitefly
observation was made in August which is the time of the heaviest infestation. Ten plants from each plot
and three leaves from each plant (lower, medium and upper parts) were taken for investigation of
whitefly population. Eggs, larvae and pupae numbers were determined on the leaves. Seventy two
cultivars were found to be highly resistant, 46 cultivars resistant, 43 cultivars moderately resistant, 23
cultivars susceptible and 18 cultivars highly susceptible. Understanding of genetic control of resistance
to whitefly can enhance development of resistant cultivars that could be grown in whitefly infested
areas.
