Passive surveillance for the occurrence of the tick Ixodes scapularis Say (1821) and their infection with the Lyme borreliosis spirochaetes Borrelia burgdorferi s.l. has taken place in Canada since early 1990. Ticks have been submitted from members of the public, veterinarians, and medical practitioners to provincial, federal, and university laboratories(More)
Human myiasis caused by bot flies of nonhuman animals is rare but may be increasing. The treatment of choice is laser photocoagulation or vitrectomy with larva removal and intraocular steroids. Ophthalmomyiasis caused by Hypoderma spp. should be recognized as a potentially reversible cause of vision loss.
We studied the prevalence and intensity of infestation of ectoparasites on northern fulmars (Fulmarus glacialis L.) from a breeding colony in Arctic Canada in June–August 2003. No fleas or ticks were found on any fulmars, but three species of chewing lice (Phthiraptera) were recorded: Ischnocera: Perineus nigrolimbatus (Giebel 1874), Ischnocera:(More)
Distributional ranges of the ticks Dermacentor andersoni Stiles and Dermacentor variabilis (Say) in the Canadian Prairies were determined by passive surveillance and active collection. These findings were compared with historical records of both species, particularly in the province of Saskatchewan, where the northern distributional limits of both tick(More)
Five new species and one new genus of the subfamily Harpirhynchinae (Acariformes: Harpirhynchidae) are described from birds in Canada: Harpyrhynchoides heatherae sp. nov. from Junco hyemalis (Passeriformes: Emberizidae), H. botaurus sp. nov. from Botaurus lentiginosus (Pelecaniformes: Ardeidae), H. phalaropus sp. nov. from Phalaropus lobatus(More)
We tested the effectiveness of the American Biophysics Corporation Mosquito Magnet Pro Model (ABC-PRO) to reduce mosquito abundance in an urban (Wolseley) and in a rural (Fort Whyte) setting in Winnipeg, Manitoba in 2001 and 2002. Assessment was based on comparisons with control sites by using Centers for Disease Control (CDC) light traps and landing counts(More)
Eight hundred and forty-nine and 1,503 Opisocrostis bruneri (Baker) were removed from Spermophilus franklinii (Sabine) in 1982 and 1983, respectively. Two discrete peaks in mean intensity of infestation were observed, one in early May and one in late August to early September. Overall prevalence of O. bruneri on S. franlinii was > or = 0.75. The observed(More)
Ectoparasites were collected from ospreys (Pandion haliaetus) in four study areas within the Great Lakes basin of Ontario, Canada. Two parasitic mite (Acari) species, Bonnetella fusca and Analloptes sp., were collected from nestlings. One chewing louse (Mallophaga) Kurodaia haliaeeti was collected from nestlings and adults. Prevalence and intensity of K.(More)
Little is known about the distribution and prevalence of the spotted fever group rickettsiae in Canada. We conducted active surveillance for tick-associated rickettsiae in 10 localities in Manitoba. A total of 1044 adult American dog ticks, Dermacentor variabilis (Acari: Ixodidae), were collected and screened for spotted fever group rickettsiae. Rickettsia(More)
Successful invasion by the mermithid Romanornermis eulicivorax declined linearly from 93.6 to 1.5% in Culex tarsalis and from 73.1 to 1.6% i n Aeries dorsalis larvae exposed in the laboratory at 18, 16, 14, 12, and l 0 C. Larvae of C. tarsalis were more susceptible than those of A. dorsalis at 18 and 16 C, but this relationship was reversed at 12 C. Larval(More)
