In this work the flight preference of nine species of the Scolytidae family was evaluated. These insects were captured with Escolitídeo/Curitiba and Marques/Carrano/Abreu traps, installed at heights of 1, 3, 5, 7,5, and 10m, in the Adolpho Ducke forest reserve, located at the km 22 of AM-10 road (Manaus, AM). An analysis of variance was carried out and the means were separated by the Tukey test. The results showed that, in both traps, the Xyleborus affinis Eichhoff species, Xyleborus sp.1 and Monarthrum sp.1, had preference for heights below 3m; Cryptocarenus heveae (Hagedorn) for heights above 5m, and Hypothenemus obscurus Fabricius, above 7,5m. Xylosandrus compactus Eichhoff had no preference for flight heights. On the other hand, Hypothenemus eruditus Westwood, Cryptocarenus diadematus Eggers, and Premnobius cavipennis Eichhoff presented discrepancy concerning flight preference, considering the kinds of trap utilised in this experiment.
