Ixodes scapularis Ticks Collected by Passive Surveillance in Canada: Analysis of Geographic Distribution and Infection with Lyme Borreliosis Agent Borrelia burgdorferi
The study suggests that B. burgdorferi-infected I. scapularis can be found over a wide geographic range in Canada, although most may be adventitious ticks carried from endemic areas in the United States and Canada by migrating birds. Expand
Effects of Discharge and Substrate Stability on Density and Species Composition of Stream Insects
Insect density decreased up to 94% at the most unstable stream reach following summer and autumn spates when 8 and 12%, respectively, of the streambed paving material was at incipient motion wheres no reduction occurred in a stable riffle constr... Expand
Range Expansion of Dermacentor variabilis and Dermacentor andersoni (Acari: Ixodidae) Near their Northern Distributional Limits
Twenty-nine species of mammals and three species of birds were identified as hosts for different life stages of these ticks and range expansion of D. variabilis has resulted in a zone of sympatry at least 200 km wide. Expand
Survey of nasal mites (Rhinonyssidae, Ereynetidae, and Turbinoptidae) associated with birds in Alberta and Manitoba, Canada
The known records of host – nasal mite species in Canada are expanded from 7 to 102, a 14-fold increase, and it is predicted that at least 70 species of rhinonyssid mites can be found in Canada. Expand
Individual and group behaviour of pastured cattle in response to attack by biting flies
In 1983 and 1984 the impact of biting flies on the behaviour of pastured heifers was determined for two herds of cattle in eastern Manitoba. One herd received a whole-body spray of cypermethrin (0....
New Species and Records of Cheyletoid Mites (Acari: Cheyletoidea) from Birds in Canada
Four new species of cheyletoid mites are described from birds in Canada and a key to species for females of the genus Syringophilopsis and a table of their associated hosts are provided. Expand
Vector of Lyme borreliosis, Ixodes scapularis, identified in Saskatchewan.
Life history and production of Ephoron album (Say) (Ephemeroptera: Polymitarcidae) in the Valley River, Manitoba
Ephoron album was the dominant summer mayfly in shallow riffles in the agricultural zone of the Valley River, Manitoba, in 1982 and 1983; eggs deposited in August hatched in late May of the following year and nymphs developed rapidly during the summer months. Expand
Acari of Canada
It is conservatively estimated that nearly 10,000 species of mites occur in Canada, but the actual number could be 15,000 or more, which means that at least 70% of Canada’s mite fauna is yet unrecorded. Expand
Ectoparasites of rabbits and hares in Manitoba, Canada, with observations on age-specific dispersal in Haemodipsus setoni (Phthiraptera: Anoplura: Polyplacidae)
It appears that dispersal from parents to offspring is overwhelmingly achieved by adult lice, and the most abundant ectoparasite on cottontails was the sucking louse, Haemodipsus setoni Ewing, recorded from this host for the first time. Expand
