Multicellular organisms have evolved sophisticated defense systems to confer protection against pathogens. An important characteristic of these immune systems is their ability to act both locally at the site of infection and at distal uninfected locations. Insects rely on multiple immune responses to combat infection; one of them is RNA interference (RNAi).
