This invention relates to the use of a combination of different proteins insecticidal to Helicoverpa zea or Helicoverpa armigerain an insect resistance management process, wherein such proteins are: a) a Cry2A protein such as Cry2Aa, Cry2Ab, or Cry2Ae and b) a Cry1A, Cry1F or VIP3A protein, particularly wherein such proteins binds saturably to the insect midgut membrane of Helicoverpa zea or Helicoverpa armigera, as well as plants and seeds expressing such combination of proteins, which are used to delay or prevent the development of resistance in populations of such insect species.
