An activity recorder was used to determine if adult female southern green stink bug, Nezara viridula (L.), exhibit diel feeding behavior in the laboratory. The activity recorder simultaneously monitored separate feeding events from 11 individual adult N. viridula. Twenty-four-hour feeding tes1ts demonstrated that laboratory-reared adult female N. viridula fed for longer durations during scotophase (≈12 min/h) than photophase (≈4 min/h). This study demonstrated that an important component of N. viridula behavior had been neglected previously.
