Between August 5 and November 27, 1949, the writer studied various aspects of malaria control in Iran. During that period his services were loaned by the U. S. Public Health Service to the Imperial Iranian Government and he worked under the auspices of the Seven Year Plan Organization. The purpose of this article is to put on record some of the entomological data obtained during that experience.
Areas Visited. Traveling mostly by automobile, the writer made two extended trips to different parts of central and western Iran. (See map and accompanying list of localities where mosquitoes were collected.) On the first trip, which lasted from August 11 to September 12, the writer traveled east and northeast across the Central Plateau, then crossed the eastern end of the Elburz Mountains and descended to the Caspian Littoral. Working westward along the shore of the Caspian Sea, he spent from three to six nights at four successive bases in the provinces of Gorgan, Mazandaran, Tonekabon, and Guilan.
