AB This paper focuses on the type of cover and preserving agent influence on composition of entrapped fauna of Carabidae beetles. The research took place in the northern part of the protected landscape area of Žďárské vrchy, south from Kameničky municipality in rural district of Chrudim. Epigeic fauna was monitored one month from April 30<sup>th</sup> to June 5<sup>th</sup> 2008 - in the period of the highest activity of most Carabidae species. Traps were located in Latin square with five meter distance, using three preserving agents (formaldehyde, ethylene glycol, sodium chloride solution) and three types of covers above pitfall traps (acrylic glass cover, no cover, or wooden board put above the trap). Within the research 1123 Carabidae specimens belonging to 21 species were entrapped. The most numerous was Poecilus cupreus (915 specimens) in which also the strongest relationship to formaldehyde was detected. The redundancy analysis (RDA) from CANOCO package was used for statistical evaluation. With monitored variables, a significant influence (T = 0.137, F = 3.020, P = 0.0240) of formaldehyde on presence of some Carabidae species was confirmed (Poecilus cupreus, Amara lunicollis, Pterostichus diligens, and Bembidion guttula). Influence of the cover above the pitfall trap on species range in the trap was not confirmed (T = 0.062, F = 2.574, P = 0.0710).
