The present invention relates to an insecticidal protein combination and a method for managing insect resistance, the method for managing insect resistance comprising contacting Ostrinia sativa with at least Cry2Ab protein and Cry1Ac protein. The invention uses two insecticidal proteins, Cry1Ac protein and Cry2Ab protein, to effectively delay or prevent the Asian corn borer from developing resistance, thereby realizing the control or prevention of the Asian corn borer, so that plants can be protected to a greater extent and stabilize yield. |
