摘要:
The summer activity (pupa development and adult emergence) ofVitacea polistiformis(Harris) in 3 north central Georgia Concord grape vineyards is presented as a set of regression models of pupal development and grape berry sugar accumulation as state variables forced by degree-day input. The significant correlation between these 2 phenological progressions is a useful pest management tool which can predict the pupal developmental state from the accumulated berry sugar content.
