Pine wilt disease is one of the most serious introduced threats to coniferous forests worldwide. Its causal agent, the pinewood nematode (PWN), Bursaphelenchus xylophilus, is vectored primarily by cerambycids of the genus Monochamus Dejean throughout its native (North America) and introduced (Japan, China, Korea, Taiwan, Portugal) ranges. Despite strict import regulations and phytosanitary measures, interception records indicate that PWN and Monochamus species continue to be moved worldwide. Fol...

The Aleocharinae fauna of eastern Canada is analyzed for geographic affiliation. Only 4.9–5.9% of the fauna is Holarctic but 11.3% of species are adventive and are of Palaearctic origin. The number of species remaining to be discovered in eastern Canada as a whole and in each of its jurisdictions was estimated using simple calculations. At least 70–75 additional species are expected to be found in the region. The fauna of PE is the most poorly known as only 24 species out of an estimated 137 are...

A checklist of eastern Canadian species of Aleocharinae is provided. The fauna currently accounts for 407 verified recorded species (including one new record) in 96 genera, and 16 tribes. The taxonomic arrangement reflects the latest knowledge of the classification of this group of beetles. Tribes are arranged in taxonomic order; genera are either in taxonomic order or in alphabetical order depending on the current knowledge of the particular taxon; and species within genera are grouped in speci...
