Analysis of conobionts from ecological and environmental aspects

In the paper an account of differentiation of carpophages of conifers (conobionts) researched from 1992 to 1994 is given. The following trees were studied: Norway spruce [Picea abies (L.) KARST.], Scotch pine (Pinus sylvestris L.), silver fir (Abies alba MILL.), European larch (Larix decidua MILL.), mountain pine (Pinus mugo TURRA), Austrian pine (Pinus nigra ARN.) and stone pine (Pinus cembra L.). Results of cone and seed research of Douglas fir [Pseudotsuga menziesii (MIRB.) FRANCO] elaborated in Forest Research Institute in Zvolen by Ing. Tavoda (1993) were added. Eighteen species of insects were found and arranged according to classification of Stadnickij et al. (1978) modified by Kristek et al. (1992) to the system of topic and trophic claims.
