Abstract: This study was carried out at the Universidade Estadual Paulista, Jaboticabal Campus, SP, during the 1995/96 and 1996/97 growing seasons. It was aimed at predicting the occurrence of nymphs and adults of Piezodorus guildinii (West.), using a degree-day model. The day when egg masses and adults of the stink bug were first observed in soybean plants was used as the biofix point. The prediction of populational peaks of adults of P. guildinii was more accurate than for the occurrence of nymphs.
