Abstract

The invention provides nucleic acids, polypeptides, transgenic plants, compositions and methods for conferring pesticidal activity (e.g., insecticidal activity) to bacteria, plants, plant cells, tissues and seeds. Nucleic acids encoding the insecticidal proteins can be used to transform prokaryotic and eukaryotic organisms to express the insecticidal proteins. The recombinant organisms or compositions containing the recombinant organisms or insecticidal proteins or in combination with an appropriate agricultural carrier can be used to control an insect pest in various environments.

First claim

What is claimed is:

1. A chimeric insecticidal protein that is toxic to a lepidopteran insect pest comprising SEQ ID NO: 3.

2. The chimeric insecticidal protein according claim 1 , wherein the chimeric insecticidal protein has insecticidal activity against a Spodoptera frugiperda insect pest with resistance to a Vip3A protein or a Cry1F protein.

3. A method of controlling a lepidopteran insect pest, the method comprising delivering to the insect pest or an environment thereof a composition comprising an effective amount of the chimeric insecticidal protein of claim 1 .
