The Varroa mite, Varroa destructor Anderson & Trueman (Arachnida: Acari: Varroidae), is a severe external parasitic mite of honeybees that causes great losses of colonies globally. Four concentrations (1, 2%, 5, and 10%) of Jatropha curcas oil were tested for controlling the Varroa mite. Significant effects of reducing percentage of the mite infestation (P = 0.05) after second treatment for sealed brood and after third treatment for adult workers in all tested concentrations of J. curcas were recorded. The low concentrations 1 and 2% of J. curcas were more effective than the higher ones 5 and 10% on reduction of percentage of Varroa mite infestation. Moreover, the colonies treated with the lowest concentrations of jatropha oil had the highest amount of brood area (75.75 and 77.50 inch2) and the highest number of combs covered with bees compared with the colonies treated with the concentrations 5 and 10%. Treated colonies with the concentrations 1, 10, and 5% had a high amount of stored honey and pollen grains, 126.50, 111, and 96 inch2 and 11.25, 9.75, and 9.75 inch2, respectively. Obtained results encourage researchers to study deeply the ability of using jatropha oil in the widely field of Apicultural.

评估麻风树油提取物对螨虫，螨虫破坏者安德森和特鲁曼（Arachnida：Acari：Varroidae），蜜蜂种群（Apis mellifera L.）的影响

Varroa螨是Varroa的破坏者Anderson＆Trueman（蛛形纲：Acari：Varroidae），是蜜蜂的一种严重的外部寄生螨，在全球范围内会造成巨大的种群损失。测试了四种浓度（1、2％，5和10％）的麻风树油来控制螨虫。记录了在所有测试浓度的麻疯树中，第二次密封海豹处理后和第三次成年人处理后成虫减少螨虫侵害百分比的显着效果（P = 0.05）。低浓度的麻疯树1和2％在降低螨螨侵害百分率方面比较高的5和10％更有效。此外，用麻疯树油浓度最低的菌落的育雏面积最高（75.75和77。50英寸2），并且与浓度为5％和10％的菌落相比，被蜜蜂覆盖的梳子数量最多。浓度分别为1、10和5％的处理过的菌落具有大量的蜂蜜和花粉粒，分别为126.50、111和96 inch2，以及11.25、9.75和9.75 inch2。所获得的结果鼓励研究人员深入研究在广泛的养蜂业中使用麻风树油的能力。
