title: Effectiveness of Genes for Hessian Fly (Diptera: Cecidomyiidae) Resistance in the Southeastern United States.
abstract: The Hessian fly, Mayetiola destructor (Say) (Diptera: Cecidomyiidae), is the most important insect pest of wheat (Triticum aestivum L. subsp. aestivum) in the southeastern United States, and the deployment of genetically resistant wheat is the most effective control. However, the use of resistant wheat results in the selection of pest genotypes that can overcome formerly resistant wheat. We have evaluated the effectiveness of 16 resistance genes for protection of wheat from Hessian fly infestation in the southeastern United States. Results documented that while 10 of the genes evaluated could provide protection of wheat, the most highly effective genes were H12, H18, H24, H25, H26, and H33. However, H12 and H18 have been reported to be only partially effective in field evaluations, and H24, H25, and H26 may be associated with undesirable effects on agronomic traits when introgressed into elite wheat lines. Thus, the most promising new gene for Hessian fly resistance appears to be H33. These results indicate that identified highly effective resistance in wheat to the Hessian fly is a limited resource and emphasize the need to identify novel sources of resistance. Also, we recommend that the deployment of resistance in gene pyramids and the development of novel strategies for engineered resistance be considered.
