“…The aim of this paper was to compare abundance and richness of mosquitoes of medical importance in diverse habitats before and after the Igarapava reservoir flooding and to describe the changes in abundance of Aedes scapularis, an incriminated vector of Rocio arbovirus and adapted in man-altered environments 10,25 , Anopheles albitarsis s.l., a complex of cryptic species considered an important vector of malaria in some localities and An. darlingi, the primary vector of malaria transmission in Brazil 1,14,15,27,30,31 .…”

SUMMARYDiversity of mosquito species was evaluated in different habitats before and after the Igarapava reservoir flooding in the Grande River, Southern Cerrado of Brazil. We aimed at verifying changes in these mosquito populations in consequence of the lake formation. Four habitats were selected as sampling stations: peridomiciliary habitat, pasture, "veredas" and gallery forest patch. Bimonthly collections were made with the Shannon trap and human bait, including diurnal, crepuscular and nocturnal period of mosquito activity. The Shannon Index results from the potential vectors were compared using Student t-test. Aedes scapularis, Anopheles darlingi and An. albitarsis senso latu seasonal abundance were described with moving average and compared using χ 2 test. There were changes in the mosquito frequency in the habitats, except for the "veredas" that was 13 km away from the catchment area. The altering in mosquito species seasonal abundance suggests breeding places expansion. Diversity indexes can be used to monitor changes in mosquito vector population in environments where abrupt disturbance can alter disease transmission cycles.

“…scapularis in the epidemic areas led to the hypothesis that this mosquito was involved in the transmission of that encephalitis (Forattini et al 6,7,8 , 1978, 1978a, 1981). Its vector competence for Rocio virus transmission was tested under laboratory conditions (Mitchell and Forattini 25 , 1984; Mitchell et al 27 , 1986), Though showing some degree of variation in "per os" infection rates, the competence was demonstrated. Some hypotheses were raised to explain those variations, among them that related to the occurrence of mosquito populations with different behaviour patterns.…”

Behaviour comparisons of Aedes scapularis and Ae. serratus are presented. Results were obtained by sampling Aedes adult mosquitoes at several places in the rural anthropic environment in the Ribeira Valley region of S. Paulo State, Brazil. Aedes dominance was shared by those two species, but Ae. scapularis showed a clear tendency to frequent the modified environment, while Ae. serratus was to be found in the more preserved ones, here represented by the vestigial patchy forests. Regarding the open cultivated land and the dwelling environments, Ae. scapularis preponderates. Considering the regional developmental phases, this mosquito showed a remarkable increase in the modified environment differently from Ae. serratus that underwent a considerable decrease in migrating from the forest to the anthropic environment. As a consequence of these results it is reasonable to conclude that Ae. scapularis may be considered as an epidemiologically efficient vector and that it quite probably played this role in the Rocio encephalitis and other arbovirus epidemics.

INTRODUCTION: Besides mosquito species adapted to urban environments (Culex quinquefasciatus, Aedes aegypti and Aedes albopictus), only 15 species of Anopheles had been recorded in the State of Pernambuco. METHODS: Human-landing mosquitoes were collected in Dois Irmãos Park, in Recife. RESULTS: The first report for the state of Haemagogus janthinomys, an important vector of yellow fever virus, and 14 other species, including Trichoprosopon lampropus, a first reported for Brazil. CONCLUSIONS: The mosquito fauna in the area is diversified and has potential medical and veterinary importance.
