Abstract

FORATTINI, Oswaldo Paulo et al. Frequency of occurrence in the human environment dispersal of Culicidae mosquitoes in an area adjacent to a primitive Atlantic plain forest. Rev. Saúde Pública [online]. 1990, vol.24, n.2, pp. 101-107. ISSN 0034-8910.  http://dx.doi.org/10.1590/S0034-89101990000200004.

Results of peridomiciliar and forest environment mosquito catches are presented. By using the method single host, mosquitoes were identified according to blood-meal and thus their dispersal was observed Evidence was obtained for movements of Aedes scapularis, due apparently were appetential flights, as well as its permanence in peridomiciliar resting places. Occurrence in domestic animal shelters was recorded for this species. Peridomiciliar human bait catches showed regular occurrence of Ae. scapularis, Anopheles bellator, An. cruzii and Culex sacchettae, but anophelines abandoned the human environment for the surrounding forest. Feeding index showed clearly a preference on the part of Ae. scapularis for bovine hosts. The peridomiciliar frequency of Cx. sacchettae suggests a domiciliary tendency. The influence of large domestic animals in the human environment surrounded by primitive Atlantic plain forests, on the domiciliation of the sylvatic mosquitoes, is emphasized.
