• Hylastes

  Hylastes is a genus of crenulate bark beetles in the family Curculionidae, comprising over 90 species. Members are primarily associated with coniferous hosts, particularly pines and spruces, where they breed in stumps, roots, and stressed or dying trees. Several species are economically significant as vectors of fungal pathogens causing tree mortality. The genus has a fossil record extending to the Eocene, with Hylastes perkovskyi described from Rovno amber.

• Hylastes porculus

  Hylastes porculus is a crenulate bark beetle in the family Curculionidae, found in North America. The species has been documented as a vector of pathogenic fungi, including Leptographium terebrantis, Leptographium procerum, and Ophiostoma ips, to wounded roots of red pine (Pinus resinosa). Its role in transmitting these fungi implicates it in red pine decline disease.
