The resistance of insect populations to the existing insecticides grows fast due to their continuous use. Thus, the need for new and effective formulations is increasing. Isolated compounds of botanical origin may represent a promising solution for green pest management strategies. In this study, isofuranodiene derived from Smyrnium olusatrum L. (Apiales: Apiaceae) essential oil (EO), was nanoemulsified (3% w/w) to treat wheat kernels with two concentrations (500 and 1000 ppm) against adults and larvae of three tenebrionid beetles attacking stored products, the red flour beetle, Tribolium castaneum (Herbst), the confused flour beetle Tribolium confusum Jacquelin du Val, and the yellow mealworm beetle, Tenebrio molitor L. Mortality rates were calculated after 4, 8 and 16 h and 1, 2, 3, 4, 5, 6 and 7 days. The isofuranodiene-based nanoemulsion (NE) exhibited high adulticidal effects against T. molitor, and larvicidal activity against T. castaneum and T. confusum, reaching 98.6, 97.4 and 93.5% at 1000 ppm after 7 days of exposure, respectively. On the other hand, the NE caused low mortality rates on adults of T. castaneum and T. confusum, as well as on larvae of T. molitor, not exceeding 26.2, 10.0 and 15.6% at 1000 ppm, 7 days post-exposure, respectively. Overall, the 3% (w/w) isofuranodiene-based NE developed here has a significant potential to protect stored wheat from tenebrionid beetle infestations.

由于持续使用，昆虫种群对现有杀虫剂的抗性增长迅速。因此，对新的有效制剂的需求正在增加。植物来源的分离化合物可能代表绿色害虫管理策略的有希望的解决方案。在这项研究中，来自Smyrnium olusatrum L.（Apiales：Apiaceae）精油 (EO) 的异呋喃二烯被纳米乳化 (3% w/w) 以处理两种浓度（500 和 1000 ppm）的小麦籽粒，以对抗成虫和三种幼虫攻击储存产品的黄粉虫、红粉甲虫Tribolium castaneum (Herbst)、混淆粉甲虫Tribolium confusum Jacquelin du Val 和黄色粉虫甲虫Tenebrio molitorL. 在 4、8 和 16 小时和 1、2、3、4、5、6 和 7 天后计算死亡率。基于异呋喃二烯的纳米乳剂 (NE) 表现出很高的杀成虫效果，对T. molitor和对T. castaneum和T. confusum 的杀幼虫活性，在暴露 7 天后在 1000 ppm 时分别达到 98.6、97.4 和 93.5%。另一方面，NE 导致T. castaneum和T. confusum 的成虫以及T. molitor 的幼虫的低死亡率，暴露后 7 天，在 1000 ppm 时分别不超过 26.2、10.0 和 15.6%。总体而言，这里开发的 3% (w/w) 异呋喃二烯基 NE 具有保护储存小麦免受黄粉虫侵扰的巨大潜力。
