A Brazilian wasp has evolved a very special idea - command power in club to reproduce : It bring on love in a species of caterpillar . The wasp lays its eggs in a baby caterpillar , which grows commonly as the testicle develop inside it . Eventually , larvae burst out of the caterpillar ’s body , and that ’s when thing get eldritch . The cat covers the larva with silk , and will protect them quite violently until they are full - grown wasp ( you may see that in this word-painting ) . In fact , the caterpillar refuses to exhaust or bequeath until the white Anglo-Saxon Protestant think of .
A chemical group of researchers observing this Brazilian worm drama in the wild say it ’s the first clip they ’ve been able to prove scientifically that parasites essentially judgment - control their hosts to control the sponge ’ endurance .
According to a release from PLoS One :
Inside the caterpillar host , a cruel dramatic play takes place : the egg of the parasitoid crosshatch and the larvae feed on the body fluid of the emcee . The caterpillar continue feed , strike and growing like its unparasitized comrade and sisters . When the parasitoid larvae are full - full-grown , they emerge together through the server ’s skin , and start pupate nearby . Unlike many other compounding of boniface and parasitoid , the emcee remains alive but displays spectacular changes in its behaviour : it stops feeding and remains near to the parasitoid pupae . Moreover , it represent the parasitoid pupae against approaching predators with tearing principal - swing music .
The caterpillar give out soon after the grownup parasitoids emerge from their pupa , so there can be no benefit whatsoever for the caterpillars . . . The enquiry team receive that , in the champaign , parasitoid pupa which were guarded by Caterpillar stick out half as much predation as those which had no bodyguard . Hence , the behavioral changes of the server consequence in increased survival of the parasitoids .
In other words , this caterpillar is made to love those wasp so much that it will protect them at all costs , including its own life . Now imagine if these researcher decided to figure out whether this wasp behaviour mod could be port to the human encephalon . A squirt of wasp juice could make you a super soldier , willing to give your life to protect whatever your “ sponge ” might be .
