The host-specific nature of the Hessian fly, Mayetiola destructor (Say) and its genetic interaction with the wheat (Triticum aestivum L. em. Thell) plant results in the evolution of virulent biotypes. However, carefully planned deployment of resistant genes can delay the evolution of biotypes and maximize the stability of resistant genes. The usefulness of the Hessian fly-wheat interaction model in breeding for insect resistance in rice is discussed.
