The occurrence of apple sawfly (Hoplocampa testudinea) in Poland and infestation of apple cultivars

, : The occurrence of apple sawfly (Hoplocampa testudinea) in Poland and infestation of apple cultivars. Prace Instytutu Sadownictwa w Skierniewicach, A78; 20: 191-200

The occurrence of apple sawfly was greatest in the Warsaw and Lublin areas where fruit damage was at times up to 50%. Of the numerous apple cvs studied for apple sawfly infestation, Bancroft, Boiken and Starking were the least affected and Linda, Antonovka and Oberlander the most. However, great variations were noted between localities and years; generally the early flowering cvs were the most affected.
