The approach of food storage, especially cereals and basic human food sources, has long been considered as a problem to combat storage pests. the use of plant compounds has been suggested by researchers as an alternative to phosphine in the fight against pests.In this study, four plants such as and were evaluated based on their deadly and repellent properties of pests and insectsconsidering Iranian medicine sources.
First, plant extracts were prepared by ethanol solvent method and then, their lethal and Anti-feeding experiments were performed on rice insects (Sitophylusoryzae) in standard laboratory conditions.
Extracts of and were estimated to be 553.2, 753.6, 878.3 and 987.3 mg / ml effective dose, respectively.The results showed that Thymus daenensis extract with 90.33% with lower concentration compared to and extracts has the highest lethal effect against . Also in Anti-feedingtest, extract showed the highest Anti-feedingeffect in comparison with and extracts, respectively.
The use of plants in the control against storage pests such as rice weevils will have favorable environmental results, human health and less storage is dangerous.
长期以来，食品储存方法，尤其是谷物和人类基本食物来源的储存方法，一直被视为防治储存害虫的难题。研究人员建议使用植物化合物作为对抗害虫的磷化氢替代品。在本研究中，基于伊朗医药来源，对四种植物等进行了害虫和昆虫致死及驱避特性评估。
首先，采用乙醇溶剂法制备植物提取物，然后在标准实验室条件下对米象（Sitophylus oryzae）进行其致死和拒食实验。
提取物的有效剂量分别估计为553.2、753.6、878.3和987.3毫克/毫升。结果表明，与提取物相比，浓度较低的百里香提取物对具有最高致死效果，致死率为90.33%。此外，在拒食试验中，提取物分别与提取物相比显示出最高的拒食效果。
使用植物防治储存害虫如米象，将对环境、人类健康产生有利影响，且储存危险性较小。
