CONOPHAGOUS AND SEMINIPHAGOUS INSECTS OF NORWAY SPRUCE PICEA-ABIES (L) KARST IN THE BABIA-GORA-NATIONAL-PARK AND ITS SURROUNDINGS

During the period from 1991 to 1993 3521 insect specimens representing 12 species were obtained from 629 Norway spruce cones. This material originated from the Babia Gora National Park 50 km southwest of Krakow and its surroundings. The coenotic groups of conophages, seminiphages and parasitoids were distinguished. For each group the index of domin ance (D), stability of incidence (C), species diversity (d), and Agrel l's index of species co-existence were calculated Seed losses caused b y insects were estimated on the basis of the analyses of 46 118 seeds.
