Hylobius Germar, 1817 - (pales weevils, pitch-eating weevils)

This genus of weevils contains more than 150 species. Several of them are important pests of pine seedlings like the pine weevil, Hylobius abietis or the pales weevil, Hylobius pales. Young pine trees are preferred but older trees might also be attacked. Other conifers like spruce might also be damaged.

The larvae might feed on roots and lower parts of the trunk of live trees with the adults feeding on shoots of seedlings (e.g. H. pales). Alternatively they breed in the stump of freshly felled trees with the adults attacking the bark of nearby pine seedlings (H. abietis). During outbreaks more than half of the young pines might be killed by the weevils. Management currently relies on the use of insecticides, although biological methods like the use of entomopathogenic nematodes are under development.

Currently, the following species have been entered into the system:
