Lesser pine shoot beetle attacks pines and, to a lesser degree, species of spruce and larch in Europe. Different species of pines vary in their susceptibility to this pest.
The lesser pine shoot beetle is regarded as a significant economic pest in Europe. During outbreaks, healthy pine trees are killed by egg gallery construction, larval feeding and introduction of blue stain fungi. Adult shoot mining contributes to reduced growth and vigor. Adult shoot feeding is unsightly and can reduce the marketability of Christmas trees, especially Scotch pine which is widely planted in some regions of North America. The blue stain fungus introduced by this insect could reduce the marketability of wood products.
The lesser pine shoot beetle is not known to occur in Indiana.
