The rice weevil, (L.), and the red flour beetle, (Herbst), are key stored-product pests in Egypt and worldwide. The extensive use of synthetic insecticides has led to adverse effects on the environment, human health, and pest resistance. As a result, environmentally friendly pest management alternatives are desperately required. The botanical oils of jojoba, (L.) and rosemary, L. plants growing in Egypt were extracted, identified by gas chromatography/mass spectrometry (GC-MS), and evaluated for their insecticidal activity against and . The main constituents identified in BOs were carvyl acetate (20.73%) and retinol (16.75%) for and camphor (15.57%), coumarin (15.19%), verbenone (14.82%), and 1,8-cineole (6.76%) for The and BOs caused significant contact toxicities against and adults, providing LC values of 24.37, 68.47, and 11.58, 141.8 ppm at 3 days after treatment (DAT), respectively. oil exhibited significant fumigation toxicity against both insects; however, it was more effective against (LC = 29.52 ppm/L air) than against (LC = 113.47 ppm/L air) at 3 DAT. Although the essential oil (EO) of significantly showed fumigation toxicity for (LC = 256.1 and 0.028 ppm/L air at 1 and 3 DAT, respectively) it was not effective against . These BOs could be beneficial for establishing IPM programs for suppressing and .
米象，（L.）和赤拟谷盗，（赫布斯特），是埃及和世界范围内主要的仓储害虫。由于大量使用合成杀虫剂，对环境、人类健康和害虫抗药性产生了不利影响。因此，急需寻找环保型害虫管理替代品。从生长在埃及的霍霍巴和迷迭香植物中提取、通过气相色谱/质谱（GC-MS）鉴定并评估其对和的杀虫活性。BOs 中的主要成分分别为乙酸橙花酯（20.73%）和视黄醇（16.75%）和樟脑（15.57%）、香豆素（15.19%）、马鞭草酮（14.82%）和 1,8-桉叶油醇（6.76%）。和 BO 对和成虫产生显著的接触毒性，在处理后 3 天（DAT）时，LC 值分别为 24.37、68.47 和 11.58、141.8 ppm。霍霍巴油对两种昆虫均表现出显著的熏蒸毒性；然而，它对（LC = 29.52 ppm/L 空气）的效果比对（LC = 113.47 ppm/L 空气）更有效，在 3 DAT。尽管（L.）的精油（EO）对（LC = 256.1 和 0.028 ppm/L 空气，分别在 1 和 3 DAT）表现出显著的熏蒸毒性，但对无效。这些 BOs 可能有益于建立 IPM 计划，以抑制和。
