Most insecticides commonly used in storage facilities are synthetic, an issue that generates concerns about food safety and public health. Therefore, the development of eco-friendly pest management tools is urgently needed. In the present study, a 6% () essential oil-based nanoemulsion (HvNE) was developed and evaluated for managing , , and , as an eco-friendly wheat protectant. Larval and adult mortality was evaluated after 4, 8, and 16 h, and 1, 2, 3, 4, 5, 6, and 7 days, testing two HvNE concentrations (500 ppm and 1000 ppm). and adults and larvae were tolerant to both concentrations of the HvNE, reaching 13.0%, 18.7%, and 10.3% mortality, respectively, at 1000 ppm after 7 days of exposure. However, testing HvNE at 1000 ppm, the mortality of and larvae and adults 7 days post-exposure reached 92.1%, 97.4%, and 100.0%, respectively. Overall, the HvNE can be considered as an effective adulticide or larvicide, depending on the target species. Our results highlight the potential of . essential oil for developing green nanoinsecticides to be used in real-world conditions against key stored-product pests.
大多数常用于储存设施的杀虫剂都是合成的，这引发了人们对食品安全和公共健康的担忧。因此，迫切需要开发环保的害虫管理工具。本研究开发并评估了一种 6%（）的精油基纳米乳液（HvNE），作为一种环保的小麦保护剂，用于防治、、和。在 4、8 和 16 小时以及 1、2、3、4、5、6 和 7 天后，评估了幼虫和成虫死亡率，测试了两种 HvNE 浓度（500 ppm 和 1000 ppm）。和成虫以及幼虫对 HvNE 的两种浓度均具有耐受性，暴露 7 天后，1000 ppm 时的死亡率分别为 13.0%、18.7%和 10.3%。然而，在 1000 ppm 下测试 HvNE 时，暴露 7 天后、和幼虫以及成虫的死亡率分别达到 92.1%、97.4%和 100.0%。总体而言，HvNE 可以被认为是一种有效的成虫杀虫剂或幼虫杀虫剂，具体取决于目标物种。我们的研究结果强调了。精油在开发用于实际条件下防治关键仓储害虫的绿色纳米昆虫icides 方面的潜力。
