失望的英国研究人员日前表示,一种能够释放一种昆虫警报信息素从而防治害虫的开拓型转基因小麦作物在田间试验中失效。洛桑研究所是位于伦敦北部的一家农业科学机构,该研究所的研究人员曾希望这项在实验室中大有希望的试验——小麦在这里击退了入侵的蚜虫——能够在田间转化成功,而这将意味着农作物在生长过程中可以减少杀虫剂的使用。洛桑研究所化学生态学家Toby Disappointed British researchers said recently that a pioneering GM wheat crop that releases an insect alarm pheromone to control pests lacks in field trials. The Lausanne Institute, an agricultural science agency in northern London, had hoped that this promising experiment in the lab, where wheat repelled invading aphids, would be able to transform successfully in the field , Which will mean that the crop can reduce the use of pesticides during its growth.
