Entomologists have used a tiny wasp to help nearly eradicate the glassy-winged sharpshooter, a major agricultural pest, from Tahiti and neighboring islands. The stingless wasp attacks sharpshooter eggs by drilling a tiny hole in the egg through which the parasite lays its own egg. The wasp larva that hatches from the egg then eats the inside of the glassy-winged sharpshooter egg, killing it.
