Abstract
In field populations of the European corn borer, Ostrinia nubilalis, there is a significant inverse correlation between the prevalence of corn borer infection with the microsporidian Nosema pyrausta and the prevalence of parasitism by the introduced braconid Macrocentrus grandii where infections with N. pyrausta exceed 45%. This relationship occurs geographically and from year to year. Corn borer infection with N. pyrausta, the source of infection for M. grandii, is significantly related to corn borer density in the cornfield. These findings strongly suggest that N. pyrausta has a significant adverse affect on field populations of M. grandii and may help explain the diminishing role of this and other introduced parasites as natural controls of the corn borer in the United States.
