Abstract
The present invention is directed to controlling plant pest infestation, and particularly plant nematode infestation, by inhibiting one or more biological functions in the plant pest. The invention discloses methods and compositions for use in controlling plant pest infestation by providing one or more different recombinant double stranded RNA molecules in the diet of the pest in order to achieve a reduction in pest infestation through suppression of pest gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules, to methods for detecting cells comprising the disclosed sequences, and to methods for detecting the disclosed sequences in biological samples.

3. A method for suppressing a peptide coding sequence in a Heterodera glycines pest, comprising selecting a target polynucleotide sequence of a Heterodera glycines pest genome comprising at least from about 24 contiguous nucleotides, expressing the polynucleotide sequence as an RNA sequence that forms a double stranded RNA structure in a plant cell, and providing said plant cell in the diet of said Heterodera glycines pest, wherein uptake of the contents of said cell by said pest results in the morbidity and/or mortality of said pest, and wherein said target polynucleotide sequence is selected from the group consisting of SEQ ID NO:
- 22219, SEQ ID NO;
