Extract

Parker et al. (1955) reported the spectacular outbreaks and migrations of the migratory grasshopper, Melanoplus bilituratus (Wlk.) in 1938 and 1939 in the north-central states of South Dakota, North Dakota and Montana, U.S.A. They recorded the extension of the flights northward into the Canadian provinces of Manitoba Saskatchewan and Alberta, and mentioned that the progeny of the migrants invading southern Saskatchewan in 1939 moved further north in 1940.
