Popis: | Knowledge of the insects affecting livestock in Eastern Canada, except possibly cattle grubs, has been inadequate. The distribution and control of cattle grubs in Eastern Canada were studied by Cameron (1918), Stevenson (1934), and Gibson and Twinn (1936). Baker et al. (1950, 1955) reported the progress made in reducing cattle grub populations in the warbly fly control campaign begun in 1948 in Ontario. Occasional records of livestock pests have appeared in The Canadian Insect Pest Review and the annual reports of the Ontario Department of Agriculture. Hadwen (1923) and Hearle (1938) discussed the various pests injurious to livestock in Canada, but did not refer specifically to Ontario. |
