Abstract
This study was conducted at the Experimental Farm belonging to Sakha Agricultural Research Station, Kafr El-Sheikh, ARC, during  2016 and 2017 seasons to investigate the role of aqueous extracts of nine aromatic plants, silica nanoparticle, and the  insecticide Imidacloprid (admire) on Bemisia tabaci (Genn.) infesting tomato plants . Results showed that the highest value of unhatched  B. tabaci eggs was 84.40 and 84.60 %respectively on tomato plants treated with the highest concentration of geranium extract, which was significantly different from the other treatments. Silica nano particles killed90.99 and 91.00 %resp. of early nymphal stage , which was not significantly different from mortality caused by admire . Silica nano particles, spurge and geranium extracts prevented adult development and killed adults at levels that were not significantly different from admire . However, the extracts of four plants; geranium, peppermint, spurge and rosemary had high repellent effect against whitefly adults . The highest parasitism percentage (93.88 and 93.63% respectively) was recorded on tomato plants treated with the highest concentration of hot pepper extract, followed by 86.23 and 86.04%resp. on tomato plants sprayed with the highest concentration of sweet basil extract. While the lowest parasitism percentage (16.53 %in both the two seasons) was obtained on tomatoplants treated with imidacloprid.
