Arthropod ectoparasites of vertebrates in Canada. A brief prepared by the Biological Survey of Canada

Arthropod ectoparasites are a diverse element of the Canadian fauna, and frequently impinge upon the performance and well-being of man, domestic animals, and wildlife. The fauna is not well known, with only about 17% of the expected species recorded. The mites and chewing lice in particular need study. There is considerable potential for investigation of the ecological, physiological and systematic relationships of the ectoparasites and their hosts. Unfortunately, there has been no coordinated research effort, and much of the research has been directed only to economically important species or disease vectors. Consequently we are presented with a rather biased view of faunal relationships.The Biological Survey of Canada (Terrestrial Arthropods) therefore recommends ways to improve the state of knowledge of Canadian arthropod ectoparasites: additional resources aimed at long-term objectives, increased awareness among a variety of biological disciplines, and fruitful avenues for future research.
