Armadilha e semioquímicos para captura de scolytinae

Abstract

Coleoptera are a cause for concern in the forestry industry, since they cause great economic damage, spread easily and are difficult to control. Among them, those of the Curculionidae family (Scolytidae) stand out. Scolitines are insects that are part of the ecological succession of forest ecosystems, accelerating the decline of forests, due to their ability to attack and cause the death of living trees known as drill, wood borer, responsible for opening galleries and patches in the wood. The objective of this work was to test different colors and semiochemicals in traps for monitoring and capturing crabs in reforestation areas. Three colors (green, red and black) and five types of semiochemicals were tested, with ethanol as a witness. For the dispersion of semiochemicals, penicillin-type glasses with a bugle in the lid were used. The traps were tested in commercial eucalyptus plantation areas (Copener Florestal). They were distanced from each other at least 30 meters. To verify the best color and test the efficiency of the odor used, four traps of each color baited with kairomone and ethanol (control) were distributed. The collections were carried out fortnightly and the collected material was taken to the Entomology laboratory, at the Federal University of Recôncavo da Bahia, for counting and identification. It was observed that the most efficient trap color was red and the best semiochemical was odor 2 (under patent).
