Ecology of mosquitoes (Diptera : Culicidae) in areas of Serra do Mar StatePark, State of Sao Paulo, Brazil, II - Habitat distribution

The mosquito (Diptera: Culicidae) ecology was studied in areas of Serra do Mar State park, State of Sao Paulo, Brazil, Systematized biweekly human bai t collections were made three times a day for periods of 2 or 3 h each, in sylvatic and rural areas for 24 consecutive months (January 1991 to Decembe r 1992). A total of 24,943 adult mosquitoes belonging to 57 species were co llected during 622 collective periods. Aedes seapularis, Coquillettidia chrysonotum, Cq. venezuelensis, Wyeomyia d yari, Wy. longirostris, Wy. theobaldi and Wy. palmata were more frequently collected at swampy and at flooded areas. Anopheles mediopunctatus, Culex n igripalpus, Ae. serratus, Ae. fulvus, Psorophora ferox, Ps. albipes and the Sabethini in general, were captured almost exclusively in forested areas. An. cruzii, An. oswaldoi and An. fluminensis were captured more frequently ill a residence al-ea. However: Cx. quinquefasciatus was the only one truly eusynanthropic. An. cruzii ann Ae. scapularis were captured feeding on blood inside and aro und the residence, indicating that both species, malaria and arbovirus vect ors respectively, may be involved in the transmission of these such disease s in rural areas.
