They modified the produce a natural pheromone which aphids rele under attack from predators. The “aphid alarm the bugs flee to safety. Aphids are not the o that release the odour though. More than 400 evolved to secrete the same substance, called farnesene, or EBF, including peppermint. The doubles up as an attractant for some insects aphids, such as parasitic wasps.

An aphid-resistant wheat have huge benefits for farmers and the enviro because the plants would no longer need to be with insecticides. “The disappointing thing is that when we the field, we didn’t find any significant red settlement in the test plots,” said Toby Bruc on the trial. Details of the trial are publis Scientific Reports. (www.thegua a 30. O objetivo do experimento com trigo geneticamente modificado foi rial shows
