Abstract:

In the numerous examples of the distribution of Ae. togoi Theob. and Ae. japonicus Theob. in their natural stations in virgin territories of the Soviet Far East and in old cities and villages of Korea and Manchuria, it was possible to establish the gradual transition of these species from the natural stations to a synanthropic form of life. The primary natural station for Ae. togoi Theob. is the rocky sea coast, where this species reaches a high numerical strength in community with sea birds, on whose blood they feed. The rocky, strongly heated pools are larval biotopes. The initial natural stations for Ae. japonicus Theob. are the taiga forests, where this species never reaches a noticeable numerical strength, which is connected with their use of accidental prey. The appearance of man, even for temporary residence, close to the natural stations of both species of mosquitoes promotes a rapid concentration of them close to man, with a transition to feeding on human blood and with the partial utilization of the dwellings of man for the daytime resting places of the imago phase. The first economic stations for these mosquitoes are the newly emerging populated points light-houses on the rocky sea shore, resort settlements in the forest zone, etc.. Under these conditions the mosquitoes almost completely break away from the natural stations, if close to man. In addition to feeding, they find a sufficient number of biotopes which are suitable for the larvae.
