Abstract :The objectives of this study were to identify suitable plant species for mass rearing and to determine some biological characteristics of the predator Serangium montazerii Fürsch insert ignore into journalissuearticles values(Coleoptera: Coccinellidae); used in the biological control of Dialeurodes citri insert ignore into journalissuearticles values(Ashmead); insert ignore into journalissuearticles values(Homoptera: Aleyrodidae);. The development time, mortality rate, preoviposition, oviposition and postoviposition periods and fecundity of S. montazerii were studied on various host plants using Bemisia tabaci insert ignore into journalissuearticles values(Genn.); insert ignore into journalissuearticles values(Homoptera: Aleyrodidae);. Two cotton insert ignore into journalissuearticles values(Çukurova-1518 and Deltapine); and two eggplant insert ignore into journalissuearticles values(Pala and Çukurova topağı); cultivars were used at 25 ºC and 65 ± 5% RH in growth chambers. Additionally, life tables were constructed from the data obtained to compare the effects of different diets. The development time of S. montazerii was shortest on Çukurova-1518 insert ignore into journalissuearticles values(22.9 days); and longest on Çukurova topağı insert ignore into journalissuearticles values(28.0 days);. The total mortality of the immature stages was lowest on Çukurova-1518 insert ignore into journalissuearticles values(20.8%); and highest on Pala insert ignore into journalissuearticles values(48.9%);. The highest Ro and T levels were found on Deltapine 90. According to the results, cotton varieties constituted more suitable plant species for mass rearing due to the short development time, low mortality rate and high fecundity of S. montazerii.
