Mosquitoes use many cues to assess whether a habitat is conducive for reproduction, possibly including the presence of stimuli from aquatic macrophytes. The effect of water infusions of water hyacinth (Eichhornia crassipes), water lettuce (Pista stratioles), parrotfeather (Myriophyllum aquaticum), and water pennywort (Hydrocotyle umbellata) on mosquito oviposition and attraction was investigated. Gravid Culex quinquefasciatus deposited significantly more egg rafts in water hyacinth, water lettuce, or Bermuda hay (positive control) infusions compared to water, while water pennywort and parrotfeather infusions did not differ from water. In‐flight attraction responses of Cx. quinquefasciatus, Aedes aegypti, and Anopheles quadrimaculatus were evaluated. The strongest attraction of gravid Cx. quinquefasciatus and Ae. aegypti occurred in the presence of volatiles from infusions of water hyacinth and water lettuce, which were equal in attractiveness to hay infusion. Water pennywort and parrotfeather infusions were not attractive. Gravid An. quadrimaculatus were not attracted to aquatic plant volatiles. The results suggest that water hyacinth and water lettuce emit volatile chemicals that attract two of three mosquito species tested and stimulate oviposition by Cx. quinquefasciatus, demonstrating that the level of attraction of aquatic plant volatiles varies among species in ways that may have relevance to bait‐based detection and control methods.

羊驼库蚊，埃及伊蚊和四按蚊对水生大型植物挥发物的行为响应。

蚊子使用许多线索来评估栖息地是否有利于繁殖，其中可能包括水生植物的刺激。研究了水葫芦（Eichhornia crassipes），生菜（Pista stratioles），鹦鹉羽毛（Myriophyllum aquaticum）和水竹pen （Hydrocotyle umbellata）注水对蚊子产卵和引诱的影响。与水相比，在水葫芦，生菜或百慕大干草（阳性对照）输注液中，Gravid quinquefasciatus明显沉积了更多的蛋筏，而水竹柳和鹦鹉羽毛输注液与水没有区别。飞行中的吸引力响应Cx。quinquefasciatus，埃及伊蚊和四按蚊。妊娠Cx的最强吸引力。quinquefasciatus和Ae。埃及风信子和水生菜的挥发物存在时会产生埃及草，这与干草的吸引力相当。彭妮草水和鹦鹉羽毛输液并不吸引人。妊娠的。Quadrimaculatus没有被水生植物挥发物吸引。结果表明，风信子和生菜散发出的挥发性化学物质吸引了测试的三种蚊子中的两种，并刺激了Cx的产卵。西洋参，表明水生植物挥发物的吸引力水平在物种之间可能以与基于诱饵的检测和控制方法有关的方式变化。
