COMBINED USE OF CRY1Ca AND CRY1Ab PROTEINS TO CONTROL INSECT RESISTANCE Russian patent published in 2016 - IPC C12N15/82 A01H5/00 A01H5/10 

FIELD: biochemistry.

SUBSTANCE: invention relates to biochemistry, particularly to a transgenic plant, resistant to insect-pests such as corn owlet moths and sugar-cane borer, contains DNA which codes Cry1Ca with SEQ ID NO: 2, and DNA which codes Cry1Ab with SEQ ID NO: 3, its seeds, as well as to the method to reduce the development of resistance of the insects sugar-cane borer and corn owlet moths to proteins Cry1Ca and Cry1Ab using it. Also disclosed is a group of plants in the field comprising a plurality of said transgenic plants and are not Bacillus thuringiensis (non-Bt) plant, and seed mixture containing non-Bt seeds from non-Bt plants, and a group of said seeds. Invention also relates to the composition containing the cells expressing proteins Cry1Ab and Cry1Ca for reducing the number of lepidopterous insect-pests.

EFFECT: invention provides effective pest control in relation to corn owlet moths and sugar-cane borer.
