Dry Season Observations on the African Mosquito, Anopheles Gambiae, in Brazil in 1938¹

I. INTRODUCTION During the first six months of 1938 the occurrence of an unusually severe outbreak of malaria in the Assú and Mossoró River valleys of Rio Grande do Norte and in the rich and heavily populated Jaguaribe valley in Ceará (Souza Pinto, Belo Mota, E. Chagas) forcibly called attention to the rapidly increasing gravity of the problem created by the presence in Brazil (Shannon 1930, 1938) of the African mosquito Anopheles gambiae (Giles, 1902). The situation was so serious that the Federal Government in August opened a special credit for the organization of an emergency service,² and in September the International Health Division of The Rockefeller Foundation voted funds for a rapid survey of the actual distribution of Anopheles gambiae, to secure information on which to base plans for possible collaboration with the federal authorities of Brazil in the campaign for the control of this mosquito.

¹ The observations on which this report is based were made under the auspices of the Cooperative Yellow Fever Service maintained jointly by the Ministry of Education and Health of Brazil and the International Health Division of The Rockefeller Foundation.

² This emergency service, known as "O Serviço de Obras Contra Malaria no Nordeste," actually began operations under the direction of Dr. Manoel Ferreira in the infested area in October during the course of the present survey. This service was the forerunner of the "Serviço de Malaria do Nordeste" which was organized by the Ministry of Education and Health of Brazil and the International Health Division of The Rockefeller Foundation.
