During the first three years, the number of larvae per stem, number of damaged leaves and percentage of damages were assessed for each ecotype and ecotypes No. 10, 11, 14, 16, 19, 20, 25 and 28 were selected for examinations in potted condition. In the fourth year of study, three mechanism of resistance (antibiosis, antixenosis and tolerance) were assessed separately using alfalfa seedlings.
