Summary: The objectives of this project were: 1. Cloning and identify potential RNAi target genes from SWD 2. Construct, design and biosynthesis dsRNAs for target genes 3. Screen for efficacy using bioassay to measure RNAi impacts on SWD 3-1. Inject dsRNA into adult flies and monitor RNAi impacts 3-2. Feed dsRNA to larvae and adults, and evaluate RNAi impacts
