Primary tabs

EOL Text

One of the most widely distributed bark beetle, the Red Turpentine Beetle is common in most coniferous forests from Northern Canada to Mexico, with the exception of the SE USA. It was recently introduced to China, where it is emerging as a damaging pest of native pines.

Life Cycle:

This species will overwinter as partly grown larvae, or as young or mature adults. The adults will find the host tress some time after the primary attacker has attacked and weakened the tree. Egg galleries are variable. No egg niches are excavated, eggs are separated by frass. Oviposition begins in late May or June. Larvae will hatch within 10 days and then mine the phloem region in groups. The larvae will mine the phloem for at least two months. The larvae will mature and create pupal cells out of frass. Generation times vary by species. In the north a generation can take a year or longer, at southern latitudes 1.5 generations can be completed in a year.
