Abstract
Holding waters of 4th-instar larvae of both Aedes triseriatus (Say) and Aedes atropalpus (Coquillett) are shown contain an oviposition attractant for Ae. triseriatus adults. It is demonstrated that the attractants are contained in the volatile fraction of this material. Experiments in which physical contact with the larval holding water is prevented demonstrate the importance of olfactory mechanisms in oviposition site selection. Acetone extracts of eggs of Ae. triseriatus do not contain an oviposition attractant for this species.
