Abstract

The importance of the mosquitoes of the genus Haemagogus in the epidemiology of sylvatic yellow fever led us to undertake laboratory experiments with the mechanism of virus transmission with the Villavicencio species. The results of the virus studies have been published in a series of papers by Bates and Roca (1945a, 1945b, 1946a, 1946b, 1946c), which include some notes on the vector mosquitoes. We became particularly interested in the effect of environmental temperature on the establishment and development of the virus in the mosquitoes, and it seemed that temperature conditions favorable for the virus were also favorable for the mosquitoes. The object of the present paper is to summarize these experiments from the entomological point of view.
