The protection of stored products from insect pests is mainly based on suppressive methods by using contact and gaseous insecticides, globally. Following their continuous and improper use, insecticide resistance has been observed in several major insect species and pose a continuous threat to the sustainability of a wide range of active ingredients that are currently in use in stored product protection. In the present work, on-site samplings of insect populations were carried out in local warehouses containing different types of cereals. The collected insects, (F.) (Coleoptera: Bostrychidae), Motschulsky (Coleoptera: Curculionidae) and (Stephens) (Coleoptera: Laemophloeidae), were reared under laboratory conditions to determine tolerance/resistance to widely used insecticides, using different diagnostic protocols. Laboratory populations of the same species were also examined for comparative purposes. Adult knock down and mortality of all populations indicated different patterns of tolerance to phosphine, deltamethrin, cypermethrin, and pirimiphos-methyl. In many cases, the recommended label doses were not able to completely control some of these populations, regardless of their origin, i.e., field-collected or laboratory. The results of the present work underline the importance of population on the efficacy of insecticides that are currently in use in stored product protection.
全球范围内，保护储存产品免受害虫侵害主要基于使用接触性和熏蒸性杀虫剂的抑制方法。在持续且不当使用这些杀虫剂之后，已在几种主要昆虫物种中观察到抗药性，这对目前用于储存产品保护的多种活性成分的可持续性构成持续威胁。在本研究中，在当地储存不同类型谷物的仓库中进行了昆虫种群的现场采样。采集的昆虫，（F.）（鞘翅目：长蠹科）、米象（鞘翅目：象甲科）和锯谷盗（鞘翅目：锯谷盗科），在实验室条件下饲养，使用不同的诊断方案来确定对广泛使用的杀虫剂的耐受性/抗性。为作比较，还对相同物种的实验室种群进行了检查。所有种群的成虫击倒率和死亡率表明对磷化氢、溴氰菊酯、氯氰菊酯和甲基嘧啶磷有不同的耐受模式。在许多情况下，无论其来源是野外采集还是实验室培养，推荐的标签剂量都无法完全控制其中一些种群。本研究结果强调了种群对目前用于储存产品保护的杀虫剂效果的重要性。
