Excerpt from The Colorado Potato Beetle in Canada Among the insects which have been introduced into Canada in modern times, none have become so widespread, so well known to all the people, or have caused such great annual losses as the Colorado potato beetle. In the half century since its first appearance in Ontario it has become established ln all of the provinces of the Dominion. The damage caused by the insect year after year and the annual expenditure necessary for its control together amount. To an enormous tax on one of the great food crops of the country. An intensive study of the insect was incepted by the senior author at Ottawa in 1919, and in that year and the following year he was assisted by Mr. J. A. Flock. Mr. H. F. Hudson undertook studies at Strathroy, Ont, in 1920 and 1921, and Mr. R. P. Gorham at Fredericton, n.b., in 1921 and 1922. In all of these investigations much new data have been assembled.
