摘　　要：利用不同剂量的电子束对烟草甲末龄幼虫进行辐照处理,研究电子束辐照对末龄幼虫42d内死亡率、完全致死时间、化蛹率和羽化率及繁殖能力的影响。结果表明,随辐照剂量的增加,末龄幼虫的死亡率逐渐上升,但并不是立即死亡,而是随继续饲养时间的延长而增加。幼虫完全致死时间随辐照剂量的增加而缩短,经480Gy以上剂量辐照的烟草甲幼虫不能羽化为成虫,经300Gy以上剂量辐照的烟草甲幼虫羽化出的成虫不能产生下一代成虫。综合考虑其他因素,300Gy的剂量可以作为阻止烟草甲末龄幼虫繁殖的有效辐照剂量。The electronic beam irradiation effects on the last instar larvae of cigarette beetle（Lasioderma serricorne Fabricius） in tobacco were studied,and the mortality in 42 days,lethal time,pupation rate,emergence rate and reproductive capacity after irradiation were measured.The results showed that the mortality increased with the increase of irradiation dosage,but the larvae did not dead immediately.The last instar larvae irradiated by the dosages higher than 480Gy could prevent the development of larvae to adults.No new generation was found after 300Gy treatment of the last instar larvae.So 300Gy irradiation could be considered as a suitable dose to prevent the reproduction of cigarette beetle of the last instar larvae in the tobacco.
