Zusammenfassung

Coptoborus ochromactonus, is a recently described scolytid pest associated with the balsa plantations, causing damage and death in young trees (from 12 to 36 months). The objectives were: Characterize the distribution of damage into the tree, define the incidence of C. ochromactonus in two years old plantations in Buena Fe and El Empalme, and evaluate dasometrics parameters of its host. C. ochromactonus has two types of damages that correspond to the initial attack, when the shaft is unsuccessful and no mass attack, whereas when it occurs in upper branches and exceed 300 drillings produces symptoms of dieback and then spike the shaft. The incidence of injury was higher in El Empalme 22.90%, attacking trees 20.10 cm dbh and 18.40 m high, relative to Buena Fe, with 11.20%, 18.20 attacking trees dbh cm and 15.90 m high
