The Mediterranean flour moth, Zeller (Lepidoptera: Pyralidae) and the confused flour beetle, Jacquelin du Val (Coleoptera: Tenebrionidae) are worldwide spread and notorious organisms of numerous stored-products. Both species are dangerous for bagged commodities as penetrators and invaders. The aim of the current study was to examine the efficacy of thiamethoxam, pirimiphos-methyl, alpha-cypermethrin, and deltamethrin, against and larvae, on different types of storage bag materials, i.e., woven propylene, biaxially oriented polypropylene and kraft paper through a (quasi)-binomial modeling approach. The type of the tested storage bag material did not affect the mortality rates of both species when treated with the tested insecticides. Thiamethoxam and pirimiphos-methyl showed statistically significant higher mortality rates on and (beta coefficient = 0.141; -value < 0.05) compared to alpha-cypermethrin and deltamethrin. In addition, exhibited significantly higher mortality rate in comparison to . Our results also showed that the tested doses and surface treatments had a significant effect on the mortality and larvae. Significantly higher mortality rates were recorded when larvae were exposed on bag materials having both surfaces treated or on the single treated surface than when they were exposed on the untreated surface. Our findings can be useful towards an effective management strategy against stored-product insect pests.
地中海粉螟，泽勒（鳞翅目：螟蛾科）和赤拟谷盗，雅克林·杜瓦尔（鞘翅目：拟步甲科）是广泛分布于全球且臭名昭著的多种储藏物害虫。这两个物种作为穿透者和入侵者，对袋装商品都很危险。本研究的目的是通过（准）二项式建模方法，研究噻虫嗪、甲基嘧啶磷、高效氯氰菊酯和溴氰菊酯对这两种害虫的幼虫在不同类型储藏袋材料（即编织聚丙烯、双向拉伸聚丙烯和牛皮纸）上的防治效果。当用测试杀虫剂处理时，测试的储藏袋材料类型对这两个物种的死亡率没有影响。与高效氯氰菊酯和溴氰菊酯相比，噻虫嗪和甲基嘧啶磷对这两种害虫显示出统计学上显著更高的死亡率（β系数 = 0.141；P值 < 0.05）。此外，赤拟谷盗的死亡率显著高于地中海粉螟。我们的结果还表明，测试剂量和表面处理对这两种害虫的幼虫死亡率有显著影响。当幼虫暴露在两面都经过处理或单面经过处理的袋材上时，记录到的死亡率显著高于暴露在未处理表面上的情况。我们的研究结果有助于制定针对储藏物害虫的有效管理策略。
