The study of factors and mechanisms involving ovipositional attractants in mosquitoes is still a relatively new area of research. Some early workers in mosquito biology suggested that gravid mosquitoes simply scattered their eggs indiscriminately on available aquatic sites; however, numerous field studies have failed to provide any real evidence for indiscriminate oviposition. The current idea is that oviposition involves not only locating an aquatic site, but the selection of an environment containing the necessary physical, chemical, and biotic factors required for larval development. It is desirable for female mosquitoes to be able to detect a breeding site that can successfully provide an environment suitable for development of their own species. According to Kramer and Mulla (1979), it is most likely that gravid females of different species use different factors in cueing in on and selecting ovipositional sites.
