The efficacy of extract and oil of some aromatic plants on the two parasitoids of B. tabaci infested kidney bean plants at Kafr EI-Sheikh were determined. The extracts of the hot-pepper, sweet basil and geranium augmented the parasitism percentage of the parasitoid Eretmocerus· mundus, 82.80, 81.80 and 80.47%, respectively, where it was 22.48 and 48.06% from the Actellic insecticide treatment and the untreated one, respectively, during 2006 season. This parameter for parasitoid Encarsia lutea was 16.16, 15.51 and 13.73% on sweet basil, geranium and spearmint treatments, respectively, comparable by 7.07 and 7.47 on the insecticide and the control.
