*2.3. Screening Test*

Fourteen eggplant CVS were cultivated in four replications in plastic pots (20 cm diameter and 14 cm height) wrapped with 50 mesh cloth to prevent the escape the aphids and contamination with other pests. After germination of seeds, only one seedling was kept in each pot, and the others were removed. Each plant in the five to six leaf growth stage was infested with four aphids and the number of aphids on each plant was recorded after 14 days. Finally, two CVS with the highest ('Pearl-Round' and 'White-Casper') and three CVS with the lowest ('Long-Green', 'Ravaya' and 'Red-Round') mean number of aphids were selected for antixenosis, antibiosis, and tolerance experiments.
