摘　　要：辐照处理在防治储粮害虫方面有重要意义,为了缓解储粮害虫的磷化氢抗性问题,采用电子加速器对磷化氢抗性品系和敏感品系赤拟谷盗成虫进行辐照处理,研究了0~1 000Gy电子束辐照对两品系赤拟谷盗的生物效应,并分析了二者对辐照的敏感性。结果表明,电子束处理对赤拟谷盗的致死效应与辐照剂量有关,两品系赤拟谷盗的致死规律大致相同。两品系赤拟谷盗成虫对电子束的敏感性存在差异,但差异不显著。两品系赤拟谷盗成虫经200Gy剂量辐照后不能产生下一代,因此,200Gy可以作为辐照防治赤拟谷盗的参考剂量。本试验为电子束防治储粮害虫提供了技术支持,对促进辐照技术在绿色储粮中的应用提供理论基础。Irradiation has important significance in pest prevention. In order to solve the insects on phosphine resistance problem in stored grain,the irradiation biological effects of 0 to 1 000 Gy electronic beam on phosphine resistant and susceptible of Tribolium castaneum（ Herbst） were studied,and the irradiation susceptibilities were compared. The results showed that the lethal effects of Tribolium castaneum（ Herbst） were varied with the irradiation dose,and the lethal rules of two strains were similar. Moreover,it was found that the irradiation susceptibilities of phosphine resistant and susceptible of Tribolium castaneum（ Herbst） had the diversity,but there was no significant difference between them. Furthermore,it was discovered that the adults of the two irradiated by the doses 200 Gy could prevent off spring reproduce. Thus,200 Gy irradiation could be considered as a reference dose for the controlling development of Tribolium castaneum（ Herbst） in stored grain. The technical support can be provided to pest prevention by electron beam irradition in this theory,and the application of irridiation technology can be promoted in the green grain storage.
