The subject invention relates in part to stacking Cry1Be toxins along with Cry1Fa toxins to prevent insects from developing resistance towards either toxin by itself. As discussed in more detail herein, the subject pair of proteins is a particularly advantageous combination, as no other pair of proteins is known to provide high levels of control and non-cross-resistant activity against both Spodoptera frugiperda (FAW) and Ostrinia nubilalis (ECB) insects. This dual, non-cross-resistant activity is also advantageous because it can reduce the number of proteins/genes needed to target these insects with multiple, non-cross-resistant proteins. This can reduce or eliminate the need for refuge acreage. Accordingly, the subject invention also relates generally to using four genes to provide three proteins for non-cross-resistant control of a first insect, and three proteins for non-cross-resistant control of a second insect. In preferred embodiments, the targeted insects are FAW and ECB.本発明は、ユーロピアンコーンボーラーおよび/またはフォールアーミーワーム昆虫を防除するための方法および植物を含み、前記植物は、昆虫による抵抗性の発達を遅らせるか阻止するための、Cry1Ab殺虫性タンパク質およびCry1Be殺虫性タンパク質、ならびにこのタンパク質の組を含む他のタンパク質の様々な組合せを含む。
