Conteúdo: | This study aimed to evaluate the resistance of tolerance type of four maize genotypes to the greenbelly stink bug, Dichelops melacanthus (Hemiptera: Pentatomidae) in a field bioassay. The genotypes SCS 154 Fortuna, SCS 155 Catarina, 2B512 PW and 2B610 PW were sowed in plots, and infested with D. melacanthus adults for seven days. After this period, an injury score was attributed to plants that were infested, and the height of plants at V5 stage, at tasseling and of cob insertion was measured at full bloom. Grain yield was also estimated at physiological maturation. Plants free of infestation were also evaluated and the reduction on the aforementioned parameters was calculated. The injury score in all genotypes was similar. The height of plants at V5 stage was significantly reduced in around 30% in all genotypes, however plants presented a recovery, and no significant difference between infested and non-infested plants was verified in the height at tasseling, height of cob insertion and yield from all genotypes. The genotypes had similar response and none stood out as tolerant to D. melacanthus.
