本研究的目的是检测蚊子的一些器官在其感觉的驱蚊材料的作用。共制备了250只目标种埃及伊蚊和斯氏按蚊雌性（15日龄），并分为5组：组1，无触角;组2，无上颌球;组3，无长鼻;组4，无额跗骨;组5，正常雌性作为对照。将含有1%山苍子、1%白千层、1%五脉白千层、1%紫花地丁和1%荆芥的五种油的混合物包含在含有20% Genapol、10%聚乙二醇、20%乙醇和50%水的复合溶剂中。此外，Bayrepel在该实验中以在相同溶剂中的20%浓度使用。在本研究中使用纯水作为对照。通过在志愿者手臂的30-cm（2）暴露区域上涂敷100 μ l的驱避材料或水来进行测试。在埃及伊蚊中，缺少某些器官（尤其是上颌球）的蚊组的叮咬和着陆百分比显著增加，而在A. stephensi，它变得不清楚哪个器官负责感知驱虫剂.
The aim of this study was to detect the role of some mosquito organs in their sensation of repellent materials. A total of 250 females (15 days old) of the target species Aedes aegypti and Anopheles stephensi were prepared and divided into five groups: group 1, without antenna; group 2, without maxillary bulbs; group 3, without proboscis; group 4, without frontal tarsus; and group 5, normal females as control. A mixture of five oils containing Litsea cubeba 1%, Melaleuca leucadendron 1%, Melaleuca quinquenervia 1%, Viola odorata 1%, and Nepeta cataria 1% was included in a complex solvent containing 20% genapol, 10% polyethylene glycol, 20% ethanol, and 50% water. Furthermore, Bayrepel was used in this experiment at a 20% concentration in the same solvent. Pure water was used as control in this study. The test was carried out by spreading 100 d of the repellent material or water on a 30-cm(2) exposure area of a human volunteer's arm. In A. aegypti, the biting and landing percentages increased significantly in those mosquito groups that lacked some organs (especially maxillary bulbs), while in A. stephensi, it became not clear which organ is responsible for perception of repellents.
