Abstract

Effects of Temperature on Infectiousness of Aedes Aegypti  Dr. Nelson C. Davis of the Laboratories of the International Sanitary Commission of the Rockefeller Foundation in Bahia, Brazil, recently finished a large series of experiments made with the aim to determine the effect that several temperatures may have on the development of the infectiousness of Stegomyia. He presented the results of his experiments. The insects were kept in an atmosphere saturated with humidity in such a form that the relative humidity could not cause any influence on the results. The mosquitoes were always submitted to experimental temperatures immediately after they had been fed on monkeys infected with yellow fever. The calculations comprised the number of days that elapsed between the day when the mosquitoes were fed on infected animals and the day in which they were fed on normal monkeys to cause the transmission of yellow fever to the latter.
