ABSTRACT

The results of the study concerning damage to dwarf shoots of Larix decidua Mill. caused by Dasineura kellneri (Henschel) have been presented. The study was conducted in 2005–2006 at three localities in the Ojców National Park in southern Poland. A total of 240 branches (each 1 m long) with 19 265 dwarf shoots, collected from 60 larches were designated to the study. The analysis showed that the percentage of dwarf shoots damaged by D. kellneri was 15.3 in 2005 and 25.0 in 2006.

The U Mann-Whithey test at the significance level of 0.05 was used in statistical analysis of the data.

Key words: Larix decidua, dwarf shoots, insect pest, Dasineura kellneri.
