Fitness of Encarsia sophia (Girault & Dodd) parasitizing Trialeurodes vaporariorum (Westwood) and Bemisia tabaci (Gennadius) biotype ‘B’ was investigated on green bean under laboratory conditions at 27 ± 2°C, 55 ± 5% RH, and a photoperiod of 14:10 (L: D) h. Development and survivorship of immatures and adults, body size, longevity and fecundity of adult females were determined. The results indicate that the fitness of E. sophia that parasitized on two different host species differed significantly. Almost all biological parameters of E. sophia parasitizing T. vaporariorum were superior to those parasitizing B. tabaci.
