Making Pesticides Out Of Scorpions

Scorpion venom is composed of a complex cocktail of poisonous peptides that immobilize animal prey on the spot. Some of the toxins in this cocktail, however, are only harmful to insects, which has prompted researchers to harness them to create a safe and ecologically sound pesticide. Scientists from Tel Aviv University's Department of Plant Sciences have isolated the genetic sequences for important neurotoxins in the scorpion venom and have also developed methods to produce and manipulate toxins to restrict their toxicity in certain insects or mammals. The findings appear in a study published in Molecular Biology and Evolution. read more
