The purpose of the research was to select the most and the least attractive clones and cultivars of short rotation willow as a feed for a allied beetle (Phratora vulgatissima). The allied beetle is a pest which dominates willow plantations in Wielkopolska. The research was carried out on clone 1033 and four Swedish cultivars: Inger, Karin, Thornhild and Tora. Varied nutritional attractiveness of the various clones and cultivars was determined. A widespread on plantations clone 1033 was the most often attacked one. Karin was a cultivar with the smallest amount of a leaf blade damage. The size and the morphological structure of leaves did not affect nutritional attractiveness for a allied beetle.
