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.
黑森瘿蚊（Mayetiola destructor (Say)，双翅目：瘿蚊科）是美国东南部小麦（Triticum aestivum L. subsp. aestivum）最重要的害虫，种植具有遗传抗性的小麦是最有效的防治方法。然而，使用抗性小麦会导致选择出能够克服先前抗性小麦的害虫基因型。我们评估了16个抗性基因在美国东南部保护小麦免受黑森瘿蚊侵害的有效性。结果表明，虽然所评估的10个基因能够保护小麦，但最有效的基因是H12、H18、H24、H25、H26和H33。然而，据报道H12和H18在田间评估中仅部分有效，并且H24、H25和H26导入优良小麦品系时可能对农艺性状产生不良影响。因此，最有前景的抗黑森瘿蚊新基因似乎是H33。这些结果表明，已确定的小麦对黑森瘿蚊的高效抗性是一种有限的资源，并强调需要鉴定新的抗性来源。此外，我们建议考虑在基因聚合体中部署抗性以及开发工程抗性的新策略。
