Southern green stink bug (SGSB), Nezara viridula (L.), damage to fresh market tomato, Lycopersicum esculentum Mill., quality was studied in 1984. The effect of SGSB density and feeding duration on the quality (grade) of tomatoes was quantified and analyzed with the log likelihood ratio test. Both bug density and feeding duration significantly affected grade. Because of highly significant interactions between SGSB density and feeding duration, the interaction term (bug - days) was used to develop polynomial regression models for the estimation of injury levels. The percentage fruit to be classified as U S grade 1, 2, or 3, with a given bug density and feeding duration, can be estimated with these equations.
