摘要：

Visual injury and grain yield were evaluated for two full-season Zea mays hybrids infested by stalk borer larvae Papaipema nebris at leaf stages one through seven. A significant linear relationship between leaf stage and injury rating was detected in all years of the study, with injury rating declining at an average rate of 0.332±0.033 points per leaf stage. In all years, infested plots yielded significantly less grain than uninfested control plots. Average yields of Pioneer hybrids 3541 and 3377 were reduced by 24.8 and 18.9%, respectively, when compared with uninfested control plots. -from Authors
