Effects of Temperature, Humidity, and Larval Weight on the Duration of Prepupal and Pupal Stages of the Pale Western Cutworm, Agrotis orthogonia Morr. (Lepidoptera: Noctuidae)1

Extract
The pale western cutworm, Agrotis orthogonia Morr., a pest of crops in the plains areas, occurs in central Alberta and Saskatchewan in Canada southward to various areas of Oklahoma, Texas, and New Mexico in the United States. It has been suggested that in the prepupal stage this cutworm is able to adapt itself to a wide range of climatic and geographic conditions and to retain a univoltine life cycle. The investigations reported here were made to determine the effects of temperature, moisture, and larval weights on the duration of the prepupal and pupal stages.
