Guest guest Posted May 20, 2003 Report Share Posted May 20, 2003 Research reveals: GE crops that are supposed to kill pests in fact nourish them In yet another blow to the credibility of the biotech industry, British and Venezuelan researchers have discovered that genetically engineered crops that are supposed to kill pests can actually nourish them instead. Among the most common genetically engineered foods are crops such as corn that are engineered to produce the naturally occurring poison, Bacillus thuringiensis (Bt). Well over 100 million acres of Bt crops have been planted worldwide. Scientists have long recognized that overuse of Bt may lead to pesticide resistance. But the British newspaper The Independent reports that the new research " adds an alarming new twist, suggesting that pests can actually use the poison as a food and that the crops, rather than automatically controlling them, can actually help them to thrive. " In their study, researchers worked with the larvae of the diamondback moth, a troublesome pest in the southern United States and the tropics. They fed one group of larvae normal cabbage leaves, and one that had been treated with a Bt toxin. Astonishingly, the larvae eating the Bt-treated leaves grew much bigger and faster -- at a 56 percent higher growth rate. The scientists discovered that the larvae " are able to digest and utilize " the toxin and may be using it as a " supplementary food. " The scientists conclude that " Bt transgenic crops could therefore have unanticipated nutritionally favorable effects, increasing the fitness of resistant populations. " Pete Riley, food campaigner for Friends of the Earth, told The Independent: " It destroys the [biotech] industry's whole case that insect-resistant GM crops can have anything to do with sustainable farming.
