摘要：
The subject invention relates in part to Cry34Ab/35Ab in combination with Cry3Ba. The subject invention relates in part to the surprising discovery that Cry34Ab/Cry35Ab and Cry3Ba 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, 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. The subject invention is supported in part by the discovery that components of these Cry protein systems do not compete with each other for binding corn rootworm gut receptors. The subject invention also relates in part to triple stacks or "pyramids" of three (or more) toxin systems, with Cry34Ab/Cry35Ab and Cry3Ba being the base pair. Thus, plants (and acreage planted with such plants) that produce these two insecticidal protein systems are included within the scope of the subject invention.
