EOL Text
Scolytus multistriatus, the European elm bark beetle or smaller European elm bark beetle, is a bark beetle species in the genus Scolytus. In Europe, while S. multistriatus acts as vector of the Dutch elm disease, caused by the Ascomycota Ophiostoma ulmi, it is much less effective than the large elm bark beetle, S. scolytus.
S. multistriatus uses vanillin and syringaldehyde as signals to find a host tree during oviposition.[1]

Adults can be about 2.2 - 3.0mm long and are reddish brown in colour. Both males and females will have a cylindrical and narrow spine arising from the anterior edge of the 2rd abdominal sternite (Bright 1976, LaBonte et. al. 2003). Teeth are usually present on the posterior-lateral margins of the 2nd to 4th abdominal sternites (LaBonte et. al. 2003).

These beetles are European in origin but have accidentally been introduced in North America (Bright 1976). They can now be found in most of Eastern Canada, and is gradually spreading westwards. Adults of S. multistriatus have been collected in Alberta.

These beetles spend most of their lives around their host trees (Ulmus spp.). Adults will be found on the trees themselves while larvae are always in the wood.

Both adults and larvae feed on Elm. The adults generally attack small twigs and the larvae feed on the wood in the trunk (Bright 1976). Large feeding damage may kill the twig or even girdle the trunk.

Overwintering generations will emerge as adults in June or July, while their progeny will emerge either in August and September, or overwinter. Some of the adults that emerge in August and September may breed and giving rise to another generation of overwintering larval individuals (Bright 1976).
