Combined use of vip3ab and cry1fa for management of resistant insects

摘要

Disclosed is a transgenic plant having trans genes encoding insecticidal proteins wherein said proteins are a Vip3Ab insecticidal protein and a Cry1F insecticidal protein. Further disclosed is a composition for controlling lepidopteran pests comprising non-human transgenic cells that express effective amounts of both a Cry1F core toxin-containing protein and a Vip3Ab protein. Further disclosed is a transgenic plant cell wherein said plant cell has a trans gene encoding a Cry1F insecticidal protein and a transgene encoding a Vip3Ab insecticidal protein, wherein said Cry1F insecticidal protein is at least 99% identical to the amino acid sequence of SEQ ID NO: 1, and said Vip3Ab insecticidal protein is at least 99% identical to the amino acid sequence of SEQ ID NO:2.
