Compositions and methods for conferring insecticidal activity to bacteria, plants, plant cells, tissues and seeds are provided. Compositions including a coding sequence for a Brevibacillus-derived delta-endotoxin polypeptide are provided. The coding sequences can be used in DNA constructs or expression cassettes for transformation and expression in plants and bacteria. Compositions also include transformed bacteria, plants, plant cells, tissues, and seeds. In particular, isolated delta-endotoxin nucleic acid molecules are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed, and antibodies specifically binding to those amino acid sequences. In particular, the present invention provides for isolated nucleic acid molecules having nucleotide sequences encoding the amino acid sequence shown in SEQ ID NO:2, 4, 7, or 10, or the nucleotide sequence set forth in SEQ ID NO:1, 3, 5, 6, 8, 9, 11, 12, 13, 14, or 15, as well as variants and fragments thereof.
