Pityophthorus puberulus
A twig beetle in the subfamily Scolytinae, Pityophthorus puberulus is commonly associated with eastern white pine (Pinus strobus) in seed orchards. Field studies indicate it responds to the pheromone pityol, with attraction enhanced by the monoterpenes (-)-α-pinene and (-)-β-pinene. Its attraction is inhibited by S-(-)-limonene, suggesting this compound may function in host recognition and suitability assessment. The species has been documented as a bycatch in trapping programs targeting the white pine cone beetle, Conophthorus coniperda.

Tetropium parvulum
Northern Spruce Borer
Tetropium parvulum, the northern spruce borer, is a small cerambycid beetle specialized on spruce hosts. It was elevated from synonymy with T. cinnamopterum based on distinct morphological differences in larvae and adults, and exhibits strict host specificity to Picea compared to the conifer generalist T. cinnamopterum. The species has a one-year life cycle and is an economically important borer of white and Engelmann spruce logs in western Canada.
