Damage caused by the three main species of stink bugs occurring on soybean were compared in field cages (1m x 1m) containing cultivar BR 37 soybean plants. Cages were infested with adults of Nezara viridula, Piezodorus guildinii and Euschistus heros, at a level of four stink bugs/m (8/cage), for 15 days, at pod filing stage (R5-R6). Evaluations were performed every two days when dead insects were replaced. After the infestation period the insects were eliminated by endossulfan aplication. Cages containing control plants remained free of stink bugs during all crop cycle. At harvesting, the number of healthy and damaged pods/plant and yield were evaluated. Seed quality from the control and infested plants were visually classified, as good, intermediate or bad seeds and also by tetrazoliun test (damaged seeds and non viable seeds). There was no difference in yield between infested and insect free plants, but damage on seed quality varied with stink bug species. For all cases, the seed quality was lower than for control plants. Results obtained by both visual and tetrazoliun evaluations showed that plants damaged by P. guildinii had the lowest quality seeds. From 50g seed samples, the average of the seeds classificated as good was 37.3g in plants infested with P. guildinii, compared to 41.8g, 44.2g, and 46.6g in plants infested with E. heros, N. viridula and control, respectively. P. guildinii plants infested had about 18% of seed injuried and this value was higher than the 3.6% and 3.4.% of plants infested with the two other species and 0.1% of the control plants. Similar results were obtained for the percentage of non viable seed due to stink bugs damage which was 5.7% for P. guildinii.
