A survey on the occurrence of insecta of the Scolytidae family (Coleoptera) was carried out in the area of primary forest of the forest Reserve Adolpho Ducke, with flight traps Escolitídeo/Curitiba and Marques/Carrano/Abreu, installed at height of 1m; 3 m; 5 m; 7.5 m, and 10 m. The collected data were evaluated quantitatively and qualitatively. From the 7974 Scolytidae insects collected, 4131 (51.8%) were captured in the Escolitídeo/Curitiba traps and 3843 (48.2 %) in the Marques/Carrano traps. The genus Xyleborus was responsible for more than 50% of the total collection and the principal species were: Xyleborus affinis Eichhoff was predominant during the whole period of the experiment, Xyleborus sp1, Premnobius cavipennis Eichhoff, Cryptocarenus heveae (Hagedorn), Cryptocarenus diadematus Eggers, Monarthrum sp1, Hypothenemus eruditus Westwood, Hypothenemus obscurus Fabricius, and Xylosandrus compactus Eichhoff.
