Hylastes porculus

A member of the tribe Hylastini; as a crenulate bark beetle, likely exhibits characteristic features of the Hylastes genus including small size and association with coniferous hosts. Specific diagnostic features distinguishing H. porculus from congeners such as Hylastes ater or other North American Hylastes species are not documented in available sources.

North America. Documented presence in Canadian provinces: Manitoba, New Brunswick, Nova Scotia, and Ontario.

• Pinus resinosa - vector of pathogenic fungi to wounded rootsField-collected adults transmitted Leptographium terebrantis (55% of trials), Leptographium procerum (40%), and Ophiostoma ips (5%) to wounded red pine roots in caging experiments.

Vector of pathogenic fungi (Leptographium terebrantis, Leptographium procerum, Ophiostoma ips) associated with red pine decline disease.

Potential forest health concern due to role in transmitting pathogenic fungi to red pine, a commercially important timber species.

• Hylastes aterCongeneric bark beetle with overlapping geographic range and conifer host associations; specific distinguishing characters not documented in available sources.
• Dendroctonus valensCo-occurs as vector of similar pathogenic fungi to red pine; belongs to different genus within Scolytinae, generally larger and with different gallery patterns.
