SStored product pests can be detrimental to agricultural produce. As much as chemical pesticides are effective control agents, they involve several environmental and health risks. Within the framework of studies on alternative pest management methods, interest has focused on a plethora of plants whose extracts have demonstrated promising action as insecticides. and the derived neem oil have been extensively tested against many harmful insect species. In contrast, L. and its main compound, CBD, a highly concentrated cannabinoid, have not been investigated much. The present study examined the potential insecticidal activity of CBD and neem oils against 4th instar larvae of , and on wheat, rice and corn seeds. Treatment efficacy was expressed in terms of larval mortality. Mortality was observed in relation to dosage, time exposure intervals and product types. The results showed clear pesticidal activity for both oils, which at high doses induced significant mortality. The treatments produced significantly fewer offspring in the insect species tested than the control. The efficacy of treatment in progeny suppression was, as expected, dose dependent.
仓储害虫会对农产品造成损害。尽管化学农药是有效的防治剂，但它们存在若干环境和健康风险。在替代害虫管理方法的研究框架内，人们的兴趣集中在大量植物上，这些植物的提取物已显示出作为杀虫剂的良好效果。印楝油及其衍生物已针对许多有害昆虫种类进行了广泛测试。相比之下，大麻花及其主要化合物CBD（一种高浓度大麻素）尚未得到充分研究。本研究考察了CBD和印楝油对麦蛾、米象和玉米象四龄幼虫在小麦、水稻和玉米种子上的潜在杀虫活性。处理效果以幼虫死亡率表示。观察死亡率与剂量、暴露时间间隔和产品类型的关系。结果表明，两种油都具有明显的杀虫活性，高剂量时可导致显著死亡率。在所测试的昆虫种类中，处理组产生的后代明显少于对照组。正如预期的那样，处理在抑制后代方面的效果取决于剂量。
