The first outbreak of Dutch elm disease in Manitoba was recorded in 1975 in Brandon, Selkirk, and Winnipeg (Hildahl 1977). The primary vector of the disease in Canada is the native elm bark beetle, Hylurgopinus rufipes (Eichh.). The smaller European elm bark beetle, Scolytus multistriatus (Marsh.), is considered the primary vector in most of the United States. In Canada, the latter species occurs throughout most of southern Ontario, parts of south-central Quebec, and has been recorded in New Bmnswick (Sterner et al. 1976).
