Resumen de Wasp uses virus to make GM butterfly
A French team has found that the iconic monarch butterfly, famed for its long migrations, has wasp genes in its genome. The monarch is not alone. Wasp genes have been found in several butterfly and moth species, inserted by viruses that the wasps use as biological weapons. There are numerous species of parasitic wasp that lay their eggs in caterpillars. Along with the monarch butterfly, Jean-Michel Drezen, now at Francois Rabelais University in Tours France, has found DNA derived from wasps in silkworms and two kinds of armyworm moth.
