Oviposition preference of Hypera postica (Gyllenhal, 1813) in stems on two alfalfa cultivars - the multifoliolate Mnogolistna 1 and the trifoliolate Europe was studied under field conditions. The results of the three year study than in trifoliolate ones. The anatomo-morphological study of the stems showed that multifoliolate alfalfa cultivar Mnogolistna 1 has bigger stem diameter and less mechanical tissue than trifoliolate which make it more attractive to H. postica for oviposition.
