Traditional control agents are usually inconvenient for managing especially in sensitive stored products such as milled flour where those agents may cause its spoilage or have detrimental effects on health of consumers. Gamma radiation of Cobalt-60 may be hygiene, safe and effective physical control agent for controlling that low gamma radiation doses can save physicochemical aspects of milled wheat flour. Therefore, effects of low doses (0, 10, 30, 50, 70 and 90 Gy) of gamma radiation were examined on survivability, development, formation and normality of developmental stages of rust red flour beetles (larvae and pupae) and on emergence and mortality of adults. Furthermore, their direct and consequent sterilizing effect on adults was also concerned. Irradiated larvae with gamma radiation doses 70–90 Gy reduced larvae numbers up to 100%. A dose of 70 Gy was also sufficient to cause completely inhibition for next pupal development, while a dose of 50 Gy was sufficient to cause completely inhibition for consequent adult emergence. Although, 67.41–81.02% of emerged adults from irradiated pupae with radiation doses 70–90 Gy were dead or deformed, gamma radiation dose of 90 Gy was sufficient to cause complete sterility for healthy emerged adults. Irradiating adult populations with doses ranged between 50 and 90 Gy reduced adult population growth 75.00–87.50%. A dose of 30 Gy was considered as effective and economic dose for reducing 94.41–99.50% of progeny production of irradiated adults. Thus, gamma radiation dose of 90 Gy may be optimal dose to reduce the pest population and prevent the pest recovery, by killing and inhibiting development of immature stages and causing complete sterility of mature stage.

伽马辐射作为卫生物理控制剂对小麦粉中赤拟谷盗（鞘翅目：拟步甲科）种群增长的影响

传统的控制剂通常不方便管理，特别是在敏感的储存产品中，例如面粉，这些控制剂可能会导致其腐败或对消费者的健康产生不利影响。 Cobalt-60的伽马辐射可能是卫生、安全和有效的物理控制剂，低伽马辐射剂量可以改善磨粉小麦粉的理化方面。因此，研究了低剂量（0、10、30、50、70 和 90 Gy）伽马辐射对锈红粉甲虫（幼虫和蛹）的生存、发育、形成和发育阶段正常性以及羽化和羽化的影响。成年人的死亡率。此外，它们对成人的直接和后续的绝育作用也令人担忧。用 70-90 Gy 的伽马辐射剂量照射幼虫可使幼虫数量减少高达 100%。 70 Gy 的剂量也足以完全抑制下一次蛹的发育，而 50 Gy 的剂量足以完全抑制随后的成虫羽化。尽管辐射剂量为 70-90 Gy 的蛹中 67.41-81.02% 的羽化成虫死亡或畸形，但 90 Gy 的伽马辐射剂量足以导致健康羽化成虫完全不育。用 50 至 90 Gy 的剂量照射成年人群可使成年人群增长率降低 75.00-87.50%。 30 Gy 的剂量被认为是有效且经济的剂量，可以使受辐射成虫的后代产量减少 94.41-99.50%。因此，90Gy的伽马辐射剂量可能是通过杀死和抑制未成熟阶段的发育并导致成熟阶段完全不育来减少害虫种群并防止害虫恢复的最佳剂量。
