Attraction of Aedes aegypti to various binary, trinary, and quaternary blends of lactic acid and ketones with or without ammonia was studied using a dual choice olfactometer. A dose dependent attraction was observed in cases of single compounds where cyclopentanone attracted the highest percentage (36.9 ± 1.8%) of Ae. aegypti when tested alone. No significant difference was observed between the attraction levels of trinary and binary blends of lactic acid and acetone or butanone when tested against clear air. However, in competitive bioassays, the trinary blend of lactic acid, acetone, and butanone was significantly preferred over binary blends of individual compounds ( P < 0.05). Acetylacetone was weakly attractive when tested alone but showed additive attraction when blended with lactic acid. However, acetylacetone acted as an attraction inhibitor when blended with other compounds. Cyclopentanone was attractive, but enhancement of attraction was not observed when blended with other components. Addition of ammonia to binary or trinary blends of lactic acid, acetone, and/or butanone did not increase the attraction significantly. In competitive bioassays, the blends containing ammonia were significantly preferred over the blends lacking ammonia ( P < 0.05). This highlights ammonia as an essential component of synthetic blends. A quaternary blend of lactic acid, ammonia, acetone, and butanone was most attractive (65 ± 1.5%) and preferred blend of all other combinations.
使用双选嗅觉仪研究了埃及伊蚊对各种含或不含氨的乳酸与酮类二元、三元和四元混合物的吸引力。在单一化合物的情况下观察到剂量依赖性吸引力，其中环戊酮单独测试时吸引埃及伊蚊的比例最高（36.9±1.8%）。乳酸与丙酮或丁酮的三元和二元混合物在与清洁空气对照测试时，吸引力水平没有显著差异。然而，在竞争性生物测定中，乳酸、丙酮和丁酮的三元混合物比单个化合物的二元混合物更受显著偏好（P<0.05）。乙酰丙酮单独测试时吸引力较弱，但与乳酸混合时表现出加成吸引力。然而，乙酰丙酮与其他化合物混合时起到吸引抑制剂的作用。环戊酮具有吸引力，但与其他成分混合时未观察到吸引力增强。向乳酸、丙酮和/或丁酮的二元或三元混合物中添加氨并没有显著增加吸引力。在竞争性生物测定中，含氨的混合物比不含氨的混合物更受显著偏好（P<0.05）。这突出了氨作为合成混合物的重要成分。乳酸-氨-丙酮-丁酮四元混合物最具吸引力（65±1.5%），是所有其他组合中最受偏好的混合物。
