Abstract: A study of diprionids associated with spruce was done at 31 sites of the eastern part of the Czech Republic in 1988-2003. In total 45 specimens belonging to Gilpinia abieticola (6 specimens), G. hercyniae (3) and G. polytoma (36) were collected using Malaise traps, emergency traps, bark-beetle pheromone baited traps or sweeping. The spruce diprionids were recorded in 30% of the studied sites only. G. polytoma was the most abundant and it is probably bivoltine with adult activity from April to August. The results of emergence trap-monitoring in Paskovský les indicate that this species is in latency.
