By Nell Boyce ARMING mosquitoes with the venom of a scorpion sounds like a terrible idea. But researchers in Mexico say malaria could be stopped in its tracks by genetically engineered mosquitoes that produce a scorpion toxin in their gut. For years, scientists have dreamed of displacing wild mosquitoes with genetically modified insects that cannot carry the malaria parasite Plasmodium (New Scientist, 5 August 1995, p 36). Two weeks ago, researchers in Europe announced the first successful attempt at genetically modifying the malaria-carrying Anopheles mosquito. Now, in experiments on a different insect,
