利用不同剂量的电子束对杂拟谷盗幼虫、成虫进行辐照处理,研究其辐照效应。结果表明:杂拟谷盗幼虫对电子束辐照的敏感性高于成虫。幼虫经250 Gy剂量辐照后,可以完全阻止其发育为成虫,在14 d内全部死亡;成虫经250 Gy剂量辐照后,则需42 d才能全部死亡,而且不能产生下一代成虫。250 Gy的剂量可以作为电子束辐照防治杂拟谷盗的参考剂量。 Different doses of electron beam were used to irradiate the heterotrophic larvae and adult worms to study their radiation effects. The results showed that the susceptibility of Eupolyphaga larvae to electron beam irradiation was higher than that of adults. Irradiation with 250 Gy could completely prevent the development of adult larvae, and all the larvae died within 14 days. After irradiated by 250 Gy, larvae died 42 days and could not produce the next generation of adults. The dose of 250 Gy can serve as a reference dose for the control of miscellaneous grains by electron beam irradiation.
