Abstract

Cattle sucking lice, Linognathus vituli (L.) (Phthiraptera: Linognathidae), were obtained from naturally infected cattle and maintained within 'arenas' affixed to the backs of cattle confined in controlled environment chambers maintained at a constant temperature of 15°C. Temperatures measured...

Abstract

We document Amblyomma dissimile Koch (Acari: Ixodidae) parasitizing a bird in Canada. A partially engorged A. dissimile nymph was collected from a Veery, Catharus fuscescens (Stephens) (Passeriformes: Turdidae), in Toronto, Ontario during spring migration. This constitutes the first authentic host...

Abstract

Sero-prevalence of Oestridae was monitored on two large western Canadian ranches from 1992 to 1999. One ranch has had a long-term programme for therapeutic control (macrocyclic lactone based, broad spectrum parasiticide) of cattle grubs as required by legislation in the province of Alberta. The...

Abstract

Beef calves from 2 sources entering southern Alberta feedlots in the winters of 1997-98 and 1998-99, were surveyed for the presence of lice. A random sample of multiple source (MS), that is, auction market-derived, calves entering commercial feedlots and single source (SS) calves entering a...

Abstract

During the winter of 1996/7, 200 153 sera from 5906 herds, collected for the control of brucellosis, were tested for antibodies to Hypoderma species. No herds were confirmed as warble fly positive, suggesting warble fly infestation is absent from, or rarely found in, Great Britain. Between January...

Abstract

The effect of parasiticide treatment on dynamics of antigen specific antibody responses to H. lineatum was investigated in naturally infested calves from Saskatchewan, Canada. Parasiticides (1% abamectin (Endecto), at 200 µg/kg body wt, or 1% moxidectin, at either 200 or 300 µg/kg body wt) were...

Abstract

The costs and benefits of an integrated pest management control programme (insecticidal treatment followed by sterile male warble fly release) for cattle grubs (Hypoderma spp.) in Alberta are compared with costs and benefits of continuing with the present entirely chemical-based control programme....
