Citation : "Zombie insects might sound like a B-movie plot device (quicktime video) but to the emerald cockroach wasp (Ampulex compressa ), they're a tried and tested way to provide food for their hungry larvae. The wasp relies on cockroaches for its grisly life cycle but unlike many venomous predators, which paralyze their victims before eating them, the wasp's sting leaves the cockroach able to walk, but unable to initiate its own movement. Researchers have discovered that the wasps sting the cockroaches once to subdue them, then administer another, more precise sting right into their victim's brain. The venom works to block a neurotransmitter called octopamine with a similar action to dopamine, which is involved in preparations to execute complex behaviors such as walking. Then the wasp grabs the cockroach's antenna and leads it back to the nest 'like a dog on a leash', says one researcher. The team found that they could restore spontaneous walking behavior in stung cockroaches by giving them a compound that reactivates octopamine receptors in the insects' central nervous system. Researchers were also able to create their own zombies by injecting unstung cockroaches with a compound that blocks the receptors producing a similar effect to that of the venom."

Citation : Dans le meme genre, je sais plus quel parasite a un cycle très marrant (c'est sans doute un truc proche de la douve du foie).
Son hote primaire est la fourmi ou il se développe et migre dans le cerveau, il va détruire certaines zones du cerveau de façon à ce que la fourmi s'accroche par ses crocs en haut d'un brin d'herbe, ensuite le mouton (hote secondaire) broute la fourmi et le parasite se développe dans le mouton.
