Carbon dioxide (CO(2) ), 1-octen-3-ol, acetone, ammonium hydroxide, L-lactic-acid, dimethyl trisulphide and isobutyric acid were tested as attractants for two tick species, Amblyomma americanum and Dermacentor variabilis (Acari: Ixodidae), in dose-response bioassays using Y-tube olfactometers. Only CO(2) , acetone, 1-octen-3-ol and ammonium hydroxide elicited significant preferences from adult A. americanum, and only CO(2) was attractive to adult D. variabilis. Acetone, 1-octen-3-ol and ammonium hydroxide were separately evaluated at three doses against CO(2) (from dry ice) at a field site supporting a natural population of A. americanum nymphs and adults. Carbon dioxide consistently attracted the highest number of host-seeking ticks. However, for the first time, acetone, 1-octen-3-ol and ammonium hydroxide were shown to attract high numbers of A. americanum. Further research is needed to determine the utility of these semiochemicals as attractants in tick surveillance and area-wide management programmes.
在使用Y型管嗅觉仪进行的剂量反应生物测定中，对二氧化碳（CO₂）、1-辛烯-3-醇、丙酮、氢氧化铵、L-乳酸、二甲基三硫化物和异丁酸作为美洲钝眼蜱和变异革蜱（蜱螨目：硬蜱科）这两种蜱类的引诱剂进行了测试。只有二氧化碳、丙酮、1-辛烯-3-醇和氢氧化铵引起了成年美洲钝眼蜱的显著偏好，并且只有二氧化碳对成年变异革蜱有吸引力。在一个有美洲钝眼蜱若虫和成虫自然种群的野外地点，分别以三种剂量对丙酮、1-辛烯-3-醇和氢氧化铵与来自干冰的二氧化碳进行了评估。二氧化碳始终吸引到最多数量的寻找宿主的蜱。然而，丙酮、1-辛烯-3-醇和氢氧化铵首次被证明能吸引大量的美洲钝眼蜱。需要进一步研究以确定这些化感物质作为引诱剂在蜱监测和区域管理计划中的效用。
