Leia o texto para responder às questões de 28 a 30 GM wheat no more pest-resistant than ordinary crops, trial GM wheat designed to repel aphids is no more effec the bugs than standard varieties a major field tr Ian Sample June 25, 2015 A major field trial of GM wheat that is desig repel aphids (small insects) has found the crop is protected against the pests than conventional whea results come from two years of trials that compare attacks on standard wheat plants with those suffer GM version modified to release a natural aphid rep Scientists created the GM wheat strain in the that it would deter aphids, which devour the crops leave them with infections. They modified the whea produce a natural pheromone which aphids release w under attack from predators. The “aphid alarm” mak the bugs flee to safety. Aphids are not the only o that release the odour though. More than 400 plant evolved to secrete the same substance, called E-be farnesene, or EBF, including peppermint. The chemi doubles up as an attractant for some insects that aphids, such as parasitic wasps. Prior to the field trial, lab tests at Rotham that the pheromone worked as a highly-effective ap repellent. The work bolstered researchers’ hopes t the trial would demonstrate the crop’s resilience aphids in the wild. An aphid-resistant wheat crop have huge benefits for farmers and the environment because the plants would no longer need to be spra with insecticides. “The disappointing thing is that when we test the field, we didn’t find any significant reductio settlement in the test plots,” said Toby Bruce, wh on the trial.
