  • Publication number: 20190203224
    Abstract: The subject invention relates in part to Cry34Ab/35Ab in combination with Cry3Aa. The subject invention relates in part to the surprising discovery that combinations of Cry34Ab/Cry35Ab and Cry3Aa are useful for preventing development of resistance (to either insecticidal protein system alone) by a corn rootworm (Diabrotica spp.) population. As one skilled in the art will recognize with the benefit of this disclosure, corn plants producing these insecticidal Cry proteins will be useful to mitigate concern that a corn rootworm population could develop that would be resistant to either of these insecticidal protein systems alone. Plants (and acreage planted with such plants) that produce these two insecticidal protein systems are included within the scope of the subject invention.
