Rehydration Driven RNAi: A Novel Approach for Effectively Delivering dsRNA to Mosquito Larvae

The soft bodies and aquatic habitats of mosquito larvae pose a challenge for applying standard RNA-interference techniques to silence expression of target genes. Here we describe a novel technique for delivering double-stranded RNA into mosquito larvae by exploiting the larva's dehydration tolerance. Larvae were dehydrated in a NaCl solution and then rehydrated in water containing double-stranded RNA. Using larvae of Culex pipiens (L.) we...
