The biology of the two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) as influenced by feeding on leaves of eggplant Solanum melongena var. esculenta, hot pepper Capsicum fruitescens and sweet pepper Capsicum annuum were investigated under laboratory conditions at 29 ± 2 ºC and 60 ± 5% RH. It was noticed that, host plant significantly influenced development and reproduction of T. urticae. Rearing on leaves of eggplant recorded significantly shorter developmental time and greater total reproduction rates of this mite species. Adult female longevity, oviposition period and fecundity were greater when the mite reared on eggplant leaves (17.27 days; 14.13 days and 45.39 eggs), respectively. On the other hand the shortest longevity (12.87 days), the least oviposition period (10.20 days) and the lowest fecundity (19.07 eggs) were recorded with leaves of hot pepper. Moderate values of these biological parameters were recorded with leaves of sweet pepper. The mite showed greatest preference for eggplant followed by sweet pepper and hot pepper. Obtained data indicated that, the host plant quality was a highly significant factor affecting population growth parameters of this acarine pest. These results may have some practical implications in management program of T. urticae.
