Forest managers strive to replant harvested sites at the first opportunity,
usually during the winter following the cut. A delay in regeneration will
lengthen the rotation I or more years, resulting in a proportional loss
of production; and it may increase site preparation costs or vegetative
competition. However, forest managers who replant pine sites soon after
harvest often face the threat of high seedling mortality due to girdling
by pales weevil, Hylobius pales (Herbst), and pitch-eating weevil,
Pachylobius picivorus (Germar) (figures 1,2).
In the South, the pales weevil and pitch-eating weevil
are considered the most serious insect pests of first-year pine plantations
growing on recently cutover sites. Seedling mortality from weevil feeding
has been recorded as high as 90 percent, and 30 to 60 percent mortality
is not uncommon.
This publication reviews current cultural and chemical
methods of controlling these insects.
