Damage, symptoms and biology

Crypturgus pusillus is considered a “secondary” bark beetle since it attacks trees that have previously harboured other bark beetle species such as Ips typographus and Pityogenes chalcographus. It very rarely attacks live trees. It is a commensal organism (“commensal” refers to the “sharing of food”). In Europe, the insect is associated with at least 15 fungi in the Ophiostomatoid group, such as Ceratocystiopsis alba, Ceratocystiopsis minima, Ceratocystiopsis minuta, Ceratocystiopsis leucocarpa, Graphium pseudormiticum, Ophiostoma ainoae, Ophiostoma araucariae and Ophiostoma piceae.

Comments

Crypturgus pusillus originates from the Palaearctic region (Europe, Asia and North Africa). It was introduced into the eastern United States in 1868, New Brunswick in 1910, Nova Scotia in 1911, Prince Edward Island around 1976, and Newfoundland. It may have been introduced on imported lumber.
