<p>Data are from a laboratory experiment conducted to examine the effects of cold temperatures on egg survival of Ageneotettix deorum, the white-whiskered grasshopper which is a common rangeland pest species in the Northern Great Plains region. </p>
<p>Abstract from published manuscript:<br>
The effect of cold temperatures and exposure time on egg survival and hatching success were examined in the white-whiskered grasshopper, Ageneotettix deorum. Temperature treatments ranged from 4°C to -35°C, with treatment times ranging from 48 to 240 hours. Both decreasing temperatures and exposure time negatively affected egg survival, with a temperature below -25°C being lethal. Similar lethal temperatures are known for several North American grasshopper species. The relatively shallow location of A. deorum egg pods would result in increased vulnerability of eggs to cold temperatures in the absence of snow.</p>

Data quantify the egg survivorship and mortality at different cold temperatures in a laboratory setting.
Use limitations
This is a laboratory experiment intended to assess the impacts of winter temperatures on egg mortality of one grasshopper species. The data may not reflect survivorship in field settings as it does not take into account other field variables, or differences between grasshopper species.
Laboratory experiment conducted at Northern Plains Agricultural Research Laboratory, Sidney, Montana, United States of America; Grasshoppers were collected from Little Missouri National Grasslands, North Dakota, United States of America
