-Abstract
: The aim of this study was to compare the effects of spraying the volatile oils of Ocimum basilicum L. and Pelargonium graveolens L., two aromatic plants and intercropping these plants with P. vulgaris L. var. Morgan, on the population of Bemisia tabaci and Tetranychus urticae. The results demonstrated that B. tabaci and T. urticae (eggs and adults) populations were lowered by intercropping with P. graveolens and O. basilicum. The populations of the B. tabaci in the two seasons varied significantly between the different treatments. Citronello (28.99%) and Geraniol (14.8%) were the principal volatile chemicals found in geranium. The volatile chemicals found in basil were beneol (16.56%) and linalool (77.96%). Low populations of B. tabaci nymphs were observed in intercropping with geranium and spraying geranim oil in two seasons. The intercropping with geranium had the lowest mean population of T. urticae in two seasons. The basil oil was more effective on T. urticae than on B. tabaci nymphs; the oil was better than intercropping with basil on eggs and adults of T. urticae and B. tabaci. The essential oils that produced a stronger repellent effect on T. urticae compared to control were O. basilicum and P. graveolens. The intercropping with geranium caused a reduced population of T. urticae. All growth parameters of the crop were improved by intercropping with basil or geranium. Chlorophyll was increased by intercropping compared with other treatments. Also, the highest yield was achieved by intercropping in two seasons.
