Abstract
The construction of dams turns moving water into peaceful lakes and the formation of these lakes is often accompanied by man made mosquito problems. After the construction of Gavins Point Dam and the impoundment of Lewis and Clark Reservoir, a marked increase in the mosquito population occurred. Since one of the two dominant species found in this area was Culex tarsalis, the known primary vector of western encephalitis, a severe public health hazard accompanied this build up of mosquitoes. The other abundant species was the noxious pest of man, Aedes vexans, and its presence should not be minimized since noxious mosquitoes now are recognized as of significance to public health. These two species comprised approximately 90 percent of the total mosquito population present in this area.
The purpose of my study was to define the mosquito problems associated with this reservoir and on the bases of the findings to outline a suitable program of control.
In the course of my study during the summers of 1959 and 1960, I feel that it was significantly demonstrated that both C. tarsalis and A. vexans can be adequately controlled on this reservoir through the use of water level management.
