在对雌性 Toxorhynchites moctezuma (Dyar & Knab) 和 Toxorhynchites amboinensis (Doleschall) 的触角电图研究中，从现场轮胎部分采集的水样的乙醚提取物显示出活性。此外，还记录了两种毒嘴蚊物种的触角电图，其中发现了七种化合物，这些化合物通常存在于含有腐烂叶子的水中，并且已知是其他蚊子物种的产卵引诱剂。这些化合物是4-甲基环己醇、苯酚、吲哚、3-甲基吲哚、间甲酚、邻甲酚和对甲酚。这些化合物的响应阈值范围为雌性触角 1 x 10(-4) μg 至 1 μg（雄性触角 100 μg）。这些结果为毒蛇类产卵引诱剂的行为研究提供了基础。
Ether extracts of water samples taken from tyre sections in the field were shown to be active in electroantennogram studies with female Toxorhynchites moctezuma (Dyar & Knab) and Toxorhynchites amboinensis (Doleschall). In addition, electroantennograms were recorded from both Toxorhynchites species for seven compounds found commonly in water containing decaying leaves and known to be oviposition attractants for other mosquito species. The compounds were 4-methylcyclohexanol, phenol, indole, 3-methylindole, m-cresol, o-cresol and p-cresol. The response thresholds for these compounds ranged between 1 x 10(-4) mu g and 1 mu g for female antennae (100 mu g for male antennae). These results provide a basis for behavioural studies of oviposition attractants for the Toxorhynchites species.
