Description

This guide is intended to provide confined feeding operations (CFO) owners or operators with knowledge of fly biology, identification of common fly species found in Alberta CFOs, and management options for fly control. The information provided will assist CFO owners or operators in designing and implementing a fly management program specific to their operation. The provided checklists are a tool for CFO owners or operators to help identify sites where flies may be breeding on their operation. They can also be used as weekly cleanup and maintenance schedules for key fly breeding habitats.

Description

Black flies, which number about 100 species in Canada, occur in varying abundance in all parts of the country. Adult females feed on blood, causing irritation and discomfort to humans, domestic and wild mammals and birds. Apart from the annoyance and discomfort, black flies cause economic losses through reduced beef and milk production, reduced efficiency of agricultural and industrial workers, and spread of diseases. In Canada, black flies transmit blood-borne parasites to turkeys, geese, and ducks. Naive cattle (not previously exposed) have died following a heavy attack by black flies in Alberta.

Description

The warble is a major economic pest of cattle in Alberta. Warble grubs, which are the larval stage of the "heelfly," spend over nine months in cattle as internal parasites. During this period they damage the meat and hide of infested animals and are responsible for reduced milk production in lactating cattle and lower weight gains in calves. Both cattlemen and packers incur severe economic losses in the absence of a warble management program. In Alberta, there is a province-wide organized warble control program helping Alberta cattlemen and the packing industry. According to the Agricultural Pest Act, all Alberta producers must take active measures to control warbles in their cattle. To manage warbles at the farm level, it is necessary to understand the biology of the insect and the method of action of the various pest control products.
