Aedes aegypti is the key vector of three important arboviral diseases -dengue, yellow fever and chikungunya. To identify volatile chemicals which could be used in odour based traps for Aedes mosquito surveillance, a few synthetic compounds and compound blends have been evaluated in an indigenously designed olfactometer. A total of 24 compounds and seven compound blends were screened against unfed adult female Ae. aegypti mosquitoes for attraction and compared with control group. The attractancy or repellency index of the test material to mosquitoes was calculated and rated them as class-1, class-2 and class-3 with rating values ranging 1-15, 16-33 and 34-100 respectively. Out of the 24 compounds tested, six were showing significant attractancy (P < 0.05) and among that 1-octene-3-ol showed maximum attractancy with a rating value of 57.81. Sixteen compounds showed significant repellency (P < 0.05) and among that with a rating value of 72.47, 1-hexene-3-ol showed strong repellent action against Ae. aegypti. All the seven blends showed significant mosquito attractancy (P < 0.05) and among that with a rating of 62.08 Myristic acid, Lactic acid and CO(2) blend exhibited first-rate mosquito attractancy.
埃及伊蚊是三种重要虫媒病毒病——登革热、黄热病和基孔肯雅热的主要传播媒介。为了鉴定可用于基于气味的诱蚊器来监测埃及伊蚊的挥发性化学物质，在自制的嗅觉计中评估了一些合成化合物和化合物混合物。总共对 24 种化合物和 7 种化合物混合物进行了筛选，以测试它们对未进食的成年雌性埃及伊蚊的吸引力，并与对照组进行了比较。用测试材料对蚊子的吸引力或驱避指数进行了计算，并将其分为 1 类、2 类和 3 类，评分值范围分别为 1-15、16-33 和 34-100。在测试的 24 种化合物中，有 6 种表现出显著的吸引力（P<0.05），其中 1-辛烯-3-醇表现出最大的吸引力，评分值为 57.81。16 种化合物表现出显著的驱避性（P<0.05），其中 1-己烯-3-醇的评分值为 72.47，对埃及伊蚊具有很强的驱避作用。7 种混合物均表现出显著的蚊虫吸引力（P<0.05），其中评分值为 62.08 的肉豆蔻酸、乳酸和 CO2 混合物对蚊虫具有一流的吸引力。
