INFLUENCE OF CLIMATIC FACTORS ON THE POPULATION DYNAMICS OF HAEMAGOGUS JANTHINOMYS (DIPTERA: CULICIDAE), A VECTOR OF SYLVATIC YELLOW FEVER

The influence of three climatic variables (temperature, air humidity and rainfall) on the incidence of populations of fig. janthinomys in two geographical regions of Brazil, in the states of Goias and Tocantins, was studied from February 1996 to December 1997. Rainfall significantly influenced the incidence of the populations of Hg. janthinomys between the months studied (p > 0.01). Rainfall was the positive factor determining the biological cycle of the species.
