Description

Many economic thresholds for insects attacking oilseed crops currently in use are nominal (i.e. unsupported by research). Some economic thresholds have been developed for major pests attacking crops in Western Canada. The following data have been compiled from various sources, including the guidelines published by the Western Committee on Crop Pests, and indicate the economic threshold recommendations being made.

Description

Orchards, nurseries, shelterbelts and gardens can suffer economic losses and aesthetic damage because of gnawing animals. Most damage occurs from late fall until early spring when extreme weather conditions limit the available food supply. Plant damage can also be extensive during periods of drought or when rabbit and hare populations are high.

Description

Grasshoppers are a major pest of both cultivated crops and rangeland grasses in the world’s semi-arid regions. Traditionally drier areas like southern Alberta are more prone to recurring problems, but serious grasshopper infestations can occur in cropland throughout the province. Although the majority of grasshopper damage has been to cereal grains, other crops can be seriously affected. This fact sheet provides information on significant species of grasshoppers in Alberta, including each specie’s significant food supply. Information is also provide on grasshopper control and the economic threshold at which control measures become viable.

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.
