Abstract

Nymphs and adults of Melanoplus sanguinipes (Fabricius) were placed, one stage at a time, into a temperature choice chamber. Their behavior was observed while a temperature gradient was established and then allowed to collapse. The grasshoppers aggregated and remained quiescent at a temperature of about 38 °C. An implication of this preferred temperature regarding behavior in the field is discussed.
