摘　　要：利用0～2kGy电子束对不同虫态的印度谷螟进行辐照处理,研究电子束辐照对卵、幼虫、蛹发育及成虫繁殖力的影响。结果表明,印度谷螟对电子束辐照的敏感性高低依次为:卵>幼虫>蛹>成虫。辐照后试虫的孵化率、化蛹率、羽化率及成虫的繁殖力均随着辐照剂量的升高而显著降低。分别经100、250和600Gy的剂量辐照的卵、幼虫、蛹不能羽化为成虫,经600 Gy剂量辐照的成虫不能产生下一代成虫。因此,600Gy剂量的电子束辐照可以作为储烟有效防治印度谷螟的参考剂量。The electronic beam irradiation effects on different developed stages of Plodia interpunctella Hübner were studied.The hatch rate,pupation rate,emergence rate and reproductive capacity of insect after irradiation were tested.The results showed that the order of sensitivity of the life stages of Plodia interpunctella Hübner to electron beam irradiation was： egglarvapupaeadult.The hatch rate,pupation rate,emergence rate and reproductive capacity significantly decreased with the increasing of irradiation dose（P0.05）.The egg,larvae,pupae couldn＇t grow to adults after irradiation at 100,250 and 600Gy,respectively.No new generation adult was found after the adults were irradiated at 600Gy.It is concluded that 600Gy irradiation could be used as a suitable dose to prevent the reproduction of Plodia interpunctella Hübner during the storage of tobacco.
