Extract

Mortality of grasshopper eggs on the Canadian prairies is brought about by many factors, including winter temperatures. Although several authors (Parker 1930; Pickford 1966, 1976; Riegert 1967) have reported that winter temperatures can affect the mortality of grasshopper eggs, no quantitative data have been presented. This note reports the relationship between low temperatures and grasshopper egg mortality
