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.Keywords:
