Abstract

Analytical studies were conducted on the species composition of galls occurring on the leaves ofTilia cordata Mill. in the Ojców National Park in 1997–1998. The species composition of galls was identical in two years. Galls were caused by 6 species. The most numerous species wereEriophyes leiosoma (Nalepa) in 1997 andPhytoptus tetratichus tetratrichus Nalepa in 1998.

Index of occurrence frequency and Agrell’s index of species co-existence have been calculated. This index reached the highest values in both years in case ofE. leiosoma andP. tetratrichus tetratrichus.
