为评估草地贪夜蛾从玉米转移为害水稻的风险,将室内以玉米叶继代饲养10代以上的草地贪夜蛾初孵幼虫分别饲喂玉米叶和水稻叶,其后代为CnC1和CnR1;CnR1组用水稻叶继代饲养8代后再分为2组,一组继续饲喂水稻叶并繁殖1代(...展开更多 为评估草地贪夜蛾从玉米转移为害水稻的风险,将室内以玉米叶继代饲养10代以上的草地贪夜蛾初孵幼虫分别饲喂玉米叶和水稻叶,其后代为CnC1和CnR1;CnR1组用水稻叶继代饲养8代后再分为2组,一组继续饲喂水稻叶并繁殖1代(CnR8R1),另一组取食玉米并繁殖1代(CnR8C1),分别观察、记录这4个种群幼虫的历期,计算其存活率、繁殖力,测定其营养效应和中肠消化酶活性。结果表明:CnC1组...
