Sticky traps baited with pheromones for Dendroctonus rufipennis were set up in the Klaipėda port and at the Vaidotai railway station alongside temporary stored timbers and in forests along roads in June–July 2000 (21 localities across the entire Lithuania); 111 beetle species and 6 genera were detected. Eight trophic groups of beetles were identified, and among them the largest number (38.7% of species detected and 28.5% of beetle specimens) presented a decaying wood and mycetobiont beetle group. Most frequent beetles were Dasytes plumbeus (Dasytidae), Sciodrepoides watsoni (Leiodidae) and Polygraphus poligraphus (Curculionidae). Scolytinae were represented by 5 species and 83 beetle specimens, No D. rufipennis was trapped. Rhacopus sahlbergi (Eucnemidae) and Anobium nitidum (Anobiidae) beetles were caught in two localities, and the species were ascertained as new for the Lithuanian fauna. There was detected 71 new localities with the occurence of 54 beetle species rare for Lithuania.
