Abstract

Daily and seasonal changes in concentrations of whole-body lipids were examined in adult green cloverworms, Plathypena scabra (F.), to determine if seasonal trends were present. Laboratory-reared moths had a greater percentage of whole-body lipids overall compared with field-reared 5-d-old adults. Laboratory-reared males contained a significantly higher percentage of whole-body lipids than laboratory-reared females. Field-reared male adults contained a greater percentage of whole-body lipids during March, September, October, and November than those adult males reared in July and August. This may indicate a preparation for diapause or migration. Field-reared females showed no temporal differences in whole-body lipids. Inability to detect differences in females may be related to reproductive status.
