Study of the Bionomics of Aedes (Stegomyia) Polynesiensis Marks Under Laboratory Conditions.

摘要

Considerable interest is shown in the Aedes (Stegornyja) soutellaris group of mosquitoes because of their potential role as vectors of dengue and other viral diseases, but especially because A. polynesiensis is the important vector of nonperiodic filariasis. In order to be a carrier of disease organisms to man, an arthropod species not only must be attracted to man for the purpose of obtaining blood, but it must maintain a certain population density. A fairly large proportion of individuals must be capable of living long enough to permit the disease organism to develop to the infective stage. Population densities and longevity are determined, in part, by intrinsic factors such as metabolic rates and nutrition, and by extrinsic factors such as climate and competition. The especially striking adaptation exhibited by species belonging to the sub- genus Stegomyja is that the eggs are deposited above the water line in a variety of small containers, including coconut husks, tin cans, and tree holes. These eggs can withstand long periods of desiccation under certain favorable conditions, and eggs hatch when they are inundated by rising water level as would occur during a reasonably heavy rain. pg 1 JMD.
