EDIT : (vu dans les commentaires) :
These wasps have a polydnavirus built into their DNA, normally passive. When a female wasp is ready to lay eggs(in a still-living caterpillar host, to give the kids something that is still fresh when they hatch, parasitoids are scary like that) her body extracts the viral DNA sequences and packages them up as viable pathogens which are then injected, along with the eggs.La nature a inventé l'équivalent biologique des droppers de virus informatiques. C'est fou
