摘要

1. A transgenic plant containing DNA encoding the insecticidal protein Cry1Ab, and DNA encoding the insecticidal protein Cry2Aa.2. The transgenic plant of claim 1, said plant further comprising DNA encoding a third insecticidal protein, said third protein selected from the group consisting of Cry1Fa, Cry1Be, Cry1I and DIG-3.3. The transgenic plant according to claim 2, wherein said third protein is selected from the group consisting of Cry1Fa and Cry1Be, said plant further comprising DNA encoding the fourth and fifth insecticidal proteins selected from the group consisting of Cry1Ca, Cry1Da, Cry1E and Vip3Ab. . A plant seed according to any one of claims 1 to 3, wherein said seed contains said DNA. A plant field, including Bt-free refugia plants and a plurality of plants according to any one of claims 1 to 3, wherein said refugia plants comprise less than 40% of all crops in the field. The plant field according to claim 5, wherein said refugia plants comprise less than 30% of all agricultural crops in said field. A plant field according to claim 5, wherein said refugia plants comprise less than 20% of all agricultural crops in said field. The plant field according to claim 5, wherein said refugia plants comprise less than 10% of all agricultural crops in said field. The plant field according to claim 5, wherein said refugia plants comprise less than 5% of all agricultural crops in said field. A plant field according to claim 5, wherein said refugia plants are located in blocks or strips. A seed mixture containing refugia seeds from Bt-free refugia plants and a plurality of seeds according to claim 4, where said refugia seeds are less than 40%
