First studies on the biology and control of Pine bark beetles in the forests of the San Rafael industrial forest unit and adjoining areas (Dendroctonus mexicanus and D. valens)

D. mexicanus and D. valens are the most important of the four species of Dendroctonus found in the Pine forests of the Mexican Sierra Nevada. D. mexicanus, rarely found at altitudes above 2600-2700 m alt., is mainly a pest of Pinus leiophylla, but also attacks other Pines e.g. P. montezumae, P. pseudostrobus and P. ayacahuite; D. valens attacks the lower parts of trees attacked by D. mexicanus.
