Resumo: | Abstract: Among pests that attack soybeans, the stink bugs have been featured for potential damage, control difficulties and constants re-infestations. The management os these pest on soybeans should be performed based on the economic threshold level, but the development of new cultivars with different cycle characteristics, growth habits and yield potential, demand that this threshold should be reviewed. The intensity of the damage caused by stink bugs depends, among other factors, on the phenological characteristics of plant, insect and especially the infestation time and the population level present in the culture. A field study was conducted using cages to test the impact of the infestation time of a population of the neotropical brown stink bug, Euschistus heros (F.) (12 adults/m) on soybean seed yield and quality at the full seed stage (R6), in 2011/2012 soybean season, at Passo Fundo, RS. The soybean cultivar used was BMX Apolo RR, with early cycle, 5.5 maturity group and indeterminate growth habit, in completely randomized design with four treatments (infestation time of 0, 7, 14 and 21 consecutive days) and six repetitions. The results indicated that up to 12 stink bugs adults/m (1 insect/plant), during 21 days, did not reduce seed yield and cause no leaf retention. However, in seed production, the same infestation level during 7 days significantly affected the seed viability and vigor. |

O manejo dessa praga na cultura da soja deve ser realizado com base no nível de ação, porém o desenvolvimento de novos cultivares, com diferentes características de ciclo, hábito de crescimento e potencial de produção, está exigindo que esse nível seja revisado. Isso porque a intensidade dos danos causados pelos percevejos depende, entre outros fatores, das características fenológicas da planta, do inseto e, principalmente, do tempo de permanência e do nível populacional presente na cultura. Um estudo utilizando gaiolas teladas no campo foi conduzido para avaliar o efeito do tempo de permanência de uma população de Euschistus heros (F.) (12 adultos/m) no rendimento e na qualidade de sementes de soja, durante o estádio de grão cheio (R6), na safra 2011/2012, em Passo Fundo, RS. Para tanto, utilizou-se o cultivar de soja BMX Apolo RR de ciclo super-precoce, grupo de maturação 5.5 e hábito indeterminado, em delineamento inteiramente casualizado com quatro tratamentos (duração da infestação de 0, 7, 14 e 21 dias consecutivos) e seis repetições. Os resultados indicaram que a infestação de 12 adultos/m (1 percevejo/planta) por até 21 dias, no estádio de grão cheio, não reduz o rendimento de grãos e não causa retenção foliar da soja. Porém, na produção de sementes, a mesma infestação, com duração a partir de 7 dias, danificou as sementes, reduzindo a viabilidade e o vigor.
