ABSTRACT

This manual provides a practical outline of the methods used in the control of malaria in areas in North America having impounded water supply systems. The planning and surveys needed prior to actual control operations in the reservoir area are considered, as well as the actual mechanics of control. Methods used to change the natural environment in order to make it unsuitable for mosquito propagation are given in great detail. They include discussions of engineering methods, vegetation control, water level fluctuation methods and maintenance of proper conditions subsequent to the more permanent control measures. In addition, chemical larvicides, their cost, application and applicability to various conditions, and measures directed against adult mosquitoes such as mosquito proofing of houses and use of insecticides, are discussed. A section is included on general malariology and identifications of the anopheline mosquitoes concerned in malaria transmission in North America. This, as well as the rest
