DsRNA degradation in the pea aphid (Acyrthosiphon pisum) associated with lack of response in RNAi feeding and injection assay

- Absence of RNAi response by feeding and injection of dsRNA in pea aphids (Acyrthosiphon pisum).
- Degradation of dsRNA by salivary secretions and aphid hemolymph.
- Upon dsRNA injection, no effect in expression of RNA-related genes dicer-2, argonaute-2, r2d2 and sid-1.
- Pea aphids contain an Eri-1-like endocellular nuclease as in nematodes.
