试验用谷象、米象、谷蠹、锈赤扁谷盗、锯谷盗和赤拟谷盗6个品种甲虫的13个品系(有的叫小种)的各个发育期,在15℃和25℃温度下,置于密闭的熏蒸箱内熏蒸。其中已知7个品系的成虫对磷化氢抗性。结果发现除抗品系的成虫具有抗性外,其发育未成熟期即卵、幼虫、和蛹也具有抗性,在抗性品系甲虫的整个生活史中,抗性最大的是蛹。锯谷盗、赤拟谷盗、锈赤扁谷盗和谷蠹的敏感品系各发育期,在15℃和25℃温度下,密闭4天,可以控制,虽然其中后两者在15℃时的磷化氢剂量要高达2克/米~3,但相
At each developmental stage of the 13 lines (also called races) of the 6 beetles of the six species Beauveria bassiana, Mihna mongolica, Tricholoma matsutake, Achillea purpurea, ℃ temperature, placed in a closed fumigation box fumigation. Among the seven lines, adults were known to be resistant to phosphine. As a result, it was found that in addition to being resistant to the adults of the resistant line, the immature egg, larva, and pupae are also resistant to development, and the pupae are most resistant throughout the entire life span of the resistant strain beetle. The susceptible strains of Sawatus, Trichosanthes, Cotyledons and Stinky belonged to each stage of development and were confined for 4 days at 15 ° C and 25 ° C, although the latter two were at 15 ° C Phosphine dose up to 2 g / m ~ 3, but the phase
