Evaluation of resistant wheat for Hessian fly (Mayetiola destructor)

The Hessian fly (Mayetiola destructor) is a major pest of winter wheat in Oklahoma and the Southern Plains. During the 2006-2007 and 2007-2008 growing seasons, wheat lines (publically available and selected entries from the OSU wheat breeding program) were evaluated for Hessian fly resistance. Previously released wheat varieties, as well as experimental lines, were included in the study. During the first field season, larval and pupal numbers were evaluated for each wheat entry; due to inclement weather, yields could not be determined. During the second field season, larval and pupal numbers were evaluated for each entry, and yield data was also collected. Our data indicates that parental lineage has an influence on Hessian fly populations and damage. Current and future sources of resistance should be available for wheat producers in the Southern Plains.
