dc.description.abstractThe banded elm bark beetle, Scolytus schevyrewi, was first observed in Canada in Alberta in 2006. In 2007, it was found in Manitoba and Saskatchewan. Its hosts include the American elm and so, it has the potential to transmit Dutch elm disease. The beetle was studied in six communities in 2009–2011 in Manitoba and Saskatchewan to learn about its biology in the Prairies. Baited sticky traps revealed that the adult flight period is from June until October, with a peak in late summer. Unbaited sticky traps and trap logs revealed that stressed Siberian elm is the preferred host. Although S. schevyrewi larvae overwintered successfully, 15% of the overwintering individuals emerged in the spring. The main impact of S. schevyrewi is expected to be the killing of stressed Siberian elms. Such trees should be removed to avoid population outbreaks that might result in attacks on healthy Siberian and American elms.en_US
