Origin of Mosquito producing waters in the vicinity of Salt Lake City, Utah

During the course of this investigation, from 1929 to 1987, of the mosquitoes in the vicinity of Salt Lake City, some interesting data have been collected on the origin of waters that produce mosquitoes. These data are now sufficient to justify certain pertinent conclusions. As all mosquito larvae and pupae are confined to an aquatic habitat, it is important in studying the origin of mosquitoes to consider the source of mosquito producing waters. This is especially true in a semi-arid region such as Salt Lake City. Most of the mosquito breeding waters in this region are of a temporary or semi permanent nature. It has been found that in permanent bodies of water the natural enemies of mosquito larvae prevent them from developing in excessive numbers.
