大多数蚊子有两种宿主：脊椎动物和维管束植物。脊椎动物的凯洛蒙已被广泛用作诱捕器中的引诱剂，用于监测蚊子种群的成虫密度或检测病原体活动。它们还被用于蚊子生理、行为和生态学的基础实地研究。相比之下，蚊子用来为其糖类寻找植物宿主的信号化学物质根本没有被利用。目前，我们正在鉴定由白纹伊蚊、淡色库蚊和冈比亚按蚊访问的植物物种产生的挥发性化合物的诱人混合物。当这些混合物部署在监测陷阱中时，可能会有效地吸引一组独特的蚊子种群。植物化学引诱剂的主要优点是，它们引诱a)两性，b)所有年龄，包括新出现的那些，c)处于所有生殖营养状态的雌性，以及d)非滞育和繁殖滞育的雌性。它们成功使用的潜在挑战是竞争挥发物的丰富，狭隘的植物-寄主专一性，以及对植物化学线索较弱的行为反应。
Most mosquito species have 2 hosts: vertebrate animals and vascular plants. The kairomones of vertebrates have been employed extensively as attractants in traps that are used for surveillance, either to assess adult density of mosquito populations or to detect pathogen activity. They also have been employed in basic field studies of mosquito physiology, behavior, and ecology. The semiochemicals that mosquitoes use to find plant hosts for their sugar, by contrast, have not been utilized at all. Currently we are characterizing attractive blends of volatile compounds produced by plant species visited by Aedes vexans, Culex pipiens, and Anopheles gambiae. These blends may be effective in attracting a unique subset of a mosquito population when deployed in surveillance traps. The principal advantages of phytochemical attractants are that they lure a) both sexes, b) all ages, including those that are newly emerged, c) females in all gonotrophic states, and d) both nondiapausing and reproductively diapausing females. Potential challenges to their successful use are the abundance of competing volatiles, narrow plant-host specificity, and a weaker behavioral response to phytochemical cues.
