The utility of a nuclear protein-coding gene for reconstructing phylogenetic relationships within the family Culicidae was explored. Relationships among 13 species representing three subfamilies and nine genera of Culicidae were analyzed using a 762-bp fragment of coding sequence from the eye color gene, white. Outgroups for the study were two species from the sister group Chaoboridae. Sequence...

Se reportan tres especies de Anophelinae: Anopheles albimanus Wiedemann, 1820, An. marajoara Galvão y Damasceno, 1942 pseudopunctipennis Theobald, 1901 en el casco urbano periurbano Cabudare, municipio Palavecino, estado Lara, Venezuela. De acuerdo con la definición ecogeográfica vectores maláricos, las son propias zona estudiada, pero su captura e identificación constituye primera evidencia ex...

Previous studies on Culicidae in the state of Santa Catarina, Brazil, were limited to Anophelinae and Culex quinquefasciatus due to the past occurrence of malaria and filariasis but the mosquito fauna in forested areas is still almost unknown. It was carried out a survey of mosquitoes with morning biting activity in a tourist trekking trail of an Atlantic forest reserve area in the island of Sa...

Anopheles (Nyssorhynchus) albitarsis sensu lato is an important malaria vector in Brazil, especially in the Brazilian Amazon region. Chromosome preparations of fourth-instar larvae of A. albitarsis from Iranduba and Coari (AM) and Ilha Comprida (SP) were analyzed for karyotype determination and to improve cytogenetic identification of this species. Anopheles albitarsis possesses 2n = 6 chromoso...

The ecology of mosquito species (Diptera: Culicidae) was studied in areas of the Serra do Mar State Park, State of São Paulo, Brazil. The influence of the lunar cycle and the daily biting rhythms of mosquito populations were analyzed. Systematized biweekly human bait collections were made in a silvatic environment for 24 consecutive months (January 1991 to December 1992). A total of 20,591 spec...
