Oviposition Site Selection By The Tree-Hole Mosquito, Aedes Triseriatus (Say)1

The effects of 6 environmental variables upon selection of an oviposition container by colonized Aedes Triseriatus were analyzed by means of a series of overlapping factorial tests. Statistically significant and consistent preferences were demonstrated for containers with horizontal openings, rough-textured and dark-colored walls, and dark backgrounds. Water of high optical density and the presence of organic decay products were also shown to be powerful oviposition stimulants. These factors and the significant interactions that occurred among them are discussed in relation to the behavior and ecological requirements of the mosquito in nature.
