The inventors observed that short “paperclip” RNAs (pcRNAs), with partially closed ends, efficiently enter cells via a clathrin-independent pathway, are more stable than other forms of RNA and effectively facilitate transcript knockdown. This alternative RNA structure provides a novel approach to control insect pests that either are recalcitrant to RNAi or where resistance to RNAi-insecticides has arisen through changes in dsRNA uptake mechanisms.
