摘要
本研究用电子加速器辐照处理玉米象成虫以及隐藏于小麦籽粒中的玉米象卵、幼虫和蛹 ,研究不同发育阶段玉米象辐照后的繁殖力。结果表明 ,高于 1 80Gy的辐照处理的成虫不能产生后代 ,辐照处理具有明显的当代延迟发育效果 ;高于 1 80Gy剂量辐照处理玉米象的蛹 ,羽化出的成虫不能产生下一代成虫 ;高于 90Gy以上的辐照处理玉米象的幼虫和卵 ,其羽化出的成虫不能产生下一代的成虫。 1 80Gy辐照可以作为阻止不同虫态玉米象的继续繁殖下一代的有效剂量。
Effects of electronic beam irradiation on adult of Sitophilus zeamais Motschulsky and its egg, larvae, and pupae hided in the seed of wheat were studied. The results showed that adults irradiated by the doses higher than 180Gy could prevent offspring reproduce; adults from pupae irradiated by the doses higher than 180Gy could prevent offspring reproduce; adults from eggs and larvae irradiated by the doses higher than 90Gy could prevent offspring reproduce. 180Gy irradiation could prevent the reproduction of maize weevil both for adults and immature stages in the wheat. =
