The use of chemical pesticides to preserve food commodities is a global issue of concern due to their negative effect on the environment and public health. In recent years, the European Union is trying to reduce their use, favoring alternative or complementary approaches based on natural products. In this scenario, plant-borne essential oils (EOs) represent valid options for Integrated Pest Management (IPM) programs. In the present study, the insecticidal effect of eight EOs obtained from plants from different parts of the world, namely Mentha longifolia, Dysphania ambrosioides, Carlina acaulis, Trachyspermum ammi, Pimpinella anisum, Origanum syriacum, Cannabis sativa and Hazomalania voyronii, were evaluated against two stored-product insect species of economic importance, Prostephanus truncatus and Trogoderma granarium. Simulating a small-scale stored-product conservation environment, an AG-4 airbrush was used to spray maize and wheat with 500 and 1000 ppm of EOs, then T. granarium and P. truncatus were exposed to the stored products and mortality was evaluated over selected time intervals (4, 8, and 16 h, and 1, 2, 3, 4, 5, 6, and 7 days). The EO of C. acaulis exhibited high efficacy against P. truncatus adults at both tested concentrations by killing > 97% of the individuals exposed to treated maize within 3 days at 500 ppm. The EO of D. ambrosioides eliminated all T. granarium adults exposed to 1000 ppm-treated wheat 2 days post-exposure. At this exposure interval, 91.1% of the exposed T. granarium adults died on wheat treated with 1000 ppm of C. acaulis EO. The EO of M. longifolia at both tested concentrations was the most effective against T. granarium larvae, leading to 97.8% mortality at 500 ppm after 3 days of exposure, and 100% mortality at 1000 pm 2 days post-exposure. At 1000 ppm, the EOs of D. ambrosioides and P. anisum led to 95.6 and 90% mortality, respectively, to larvae exposed to treated wheat for 7 days. Overall, our research shed light on the potential of selected EOs, with special reference to M. longifolia, D. ambrosioides, C. acaulis and P. anisum, which could be considered further to develop effective and alternative grain protectants to manage P. truncatus and T. granarium infestations.

八种精油对两种主要的储藏甲虫（Prostephanus truncatus（Horn）和Trogoderma granarium Everts）的功效。
由于化学杀虫剂对环境和公共卫生的负面影响，使用化学杀虫剂来保存食品是一个全球关注的问题。近年来，欧盟试图减少其使用，赞成基于天然产物的替代或补充方法。在这种情况下，植物精油（EOs）是病虫害综合治理（IPM）计划的有效选择。在本研究中，对来自世界各地的八种EO的杀虫效果进行了评估，其中八种EO分别来自长叶薄荷，香叶木麻黄，花椰菜，香米草，chy皮，茴香，牛至，牛至，苜蓿和哈索马尼亚草具有重要经济意义的储藏产品昆虫物种，Prostephanus truncatus和Trogoderma granarium。为了模拟小规模的保存产品保存环境，使用AG-4喷枪向玉米和小麦喷洒500和1000 ppm的EO，然后将T. granarium和P. truncatus暴露于保存的产品中，并评估死亡率。选定的时间间隔（4、8和16小时，以及1、2、3、4、5、6和7天）。在两种测试浓度下，金合欢果的EO均对截短疟原虫成虫表现出高功效，通过在500天内杀死暴露于处理过的玉米中的97％以上的个体，从而杀死了它们。D. ambrosioides的EO消除了暴露后2天暴露于1000 ppm处理的小麦的所有T. granarium成虫。在此暴露时间间隔内，暴露的T. granarium成年动物中有91.1％的人死于用1000 ppm的金合欢果EO处理的小麦。在两个测试浓度下，长叶M. olio的EO对T最有效。幼虫，在暴露3天后500 ppm时死亡率为97.8％，在暴露后2天1000 pm时死亡率为100％。在1000 ppm时，D。ambrosioides和P. anisum的EOs分别导致暴露于处理过的小麦7天的幼虫的死亡率为95.6和90％。总体而言，我们的研究揭示了选定的EO的潜力，特别是对长叶毛发杜鹃，D。ambrosioides，C。acaulis和P. anisum的参考，它们可被进一步考虑用于开发有效和替代性的谷物保护剂来管理t藜和天竺葵的侵扰。
