In the experiment the population dynamics as well as the development of Myzocallis coryli on five hazel cultivars were investigated. In terms of host plant resistance to Myzocallis coryli the tested cultivars displayed very similar susceptibility. The obtained results show that no significant differences were found in aphid rm. In spite of this, due to the longest prereproductive time, the lowest fecundity and the smallest number of aphids per 10 leaves, Katalonski is less suitable cultivar for the aphids from all tested hazel cultivars
