Previous issue date: 1998-09-03 / CNPq / Faperj / In order to analyze some aspects related to the ecology of mosquitoes (Diptera: Culicidae) in areas of the State Park of the Serra do Mar, State of Sao Paulo, monthly captures were accomplished, using human bait, in three different periods of the day, in wild and domiciliary environments and 24 consecutive months, from January, 1991 to December, 1992.
In 622 samplings, 24.943 specimens of adult mosquitoes belonging to 61 species were captured. Highest frequencies were due to Cq. chrysonotum with 45,8% of the total of captured mosquitoes, followed by: Ae. serratus with 6,8%, Cq. venezuelensis with 6,5%, Ps. ferox with 5,2 and Ps. albipes with 3,1%.
Monthly averages of temperature and relative humidity of the air were inserted in the secular maximum and minimum medium limits of the 10 previous years and the one of rainfall accompanied the curve of the averages of secular tendency of the same period. Those climatic factors were decisive for the incidence of some species; temperature: An. cruzii, An. mediopunctatus, Ae. scapularis, Ae. fulvus, Cq. chrysonotum, Cq. venezuelensis, Ru. reversa, Wy. dyari, Wy. confusa, Wy. shannoni, Ph. theobaldi and Li. flavisetosus; relative humidity: Ae. serratus, Ae. scapularis, Cq. venezuelensis and Ru. reverse; rainfall: An. cruzii, Ae. scapularis, Ae. fulvus, Cq. venezuelensis Ru. reverse, Ph. theobaldi and Li. flavisetosus.
Some species were identified according to certain capture stations. Cq. chrysonotum and Cq. venezuelensis demonstrated preference for the swamp areas and puddles found in the stations A and B. An. mediopunctatus, Cx. nigripalpus, Ae. serratus, Ae. fulvus, Ps. ferox, Ps. albipes and the Sabethinae in general were captured almost exclusively in wild areas, especially in the stations B and C. The domicile located in the station D, was preferred by An. cruzii, An. oswaldoi and An. fluminensis. However, Cx. quinquefasciatus was the only eusynanthropic species.
An. cruzii and Ae. scapularis were captured accomplishing the blood repast in the intra and peridomicile, indicating that both species, vectors of etiologic agents responsible for malaria and arboviroses respectively , in other places in the coast of the State of Sao Paulo, can be involved in the domiciliary transmission of those diseases.
Except for the incidences of Tr. digitatum in the night period, the Sabethinae were captured essentially in the illuminated hours of the day. All the Anophelinae were preferably in the night samplings and the Culicinae presented nocturnal species: Cx. nigripalpus, Cq. chrysonotum and Cq. venezuelensis; of the day: Ps. ferox and Ps. albipes; and eclectic as the preference for the occurrence period: Ae. serratus, Ae. scapularis and Ae. fulvus.
The lunar phases were not decisive to the incidence of the Culicidae fauna. However, the samplings accomplished in nights of new moon were more profitable quantitatively. Ae. scapularis was captured preferably in nights of full moon. / Visando conhecer aspectos da ecologia de mosquitos (Diptera: Culicidae) em ?reas do Parque Estadual da Serra do Mar, Estado de S?o Paulo, foram realizadas capturas mensais sistematizadas, em isca humana, em tr?s diferentes per?odos do dia, em ambiente silvestre e domiciliar e ao longo de 24 meses consecutivos, de janeiro de 1991 a dezembro de 1992.
Em 622 amostragens, foram capturados 24.943 esp?cimes de mosquitos adultos pertencentes 61 esp?cies. As maiores ocorr?ncias ficaram por conta de Cq. chrysonotum com 45,8% do total de mosquitos capturados, seguida por: Ae. serratus ? 6,8%, Cq. venezuelensis = 6,5%, Ps. ferox ? 5,2 e Ps. albipes ? 3,1%.
As m?dias mensais de temperatura e umidade relativa do ar estiveram inseridas nos limites das m?dias seculares de m?xima e m?nima dos 10 anos anteriores e as de precipita??es pluviom?tricas acompanharam a curva das m?dias de tend?ncia secular do mesmo per?odo. Esses fatores clim?ticos foram determinantes para incid?ncia de algumas esp?cies; temperatura: An. cruzii, An. mediopunctatus, Ae. scapularis, Ae. fulvus, Cq. chrysonotum, Cq. venezuelensis, Ru. reversa, Wy. dyari, Wy. confusa, Wy. shannoni, Ph. theobaldi e Li. flavisetosus; umidade relativa: Ae. serratus, Ae. scapularis, Cq. venezuelensis e Ru. reversa; precipita??es pluviom?tricas: An. cruzii, Ae. scapularis, Ae. fulvus, Cq. venezuelensis Ru. reversa, Ph. theobaldi e Li. flavisetosus.
Algumas esp?cies estiveram identificadas com determinadas esta??es de captura. Cq. chrysonotum e Cq. venezuelensis demostraram prefer?ncia pelas ?reas de mangue e charcos encontradas nas esta??es A e B. An. mediopunctatus, Cx. nigripalpus, Ae. serratus, Ae. fulvus, Ps. ferox, Ps. albipes e os sabet?neos em geral foram capturados quase que exclusivamente em ?reas silvestres, especialmente nas esta??es B e C. O domic?lio localizado na esta??o D foi preferido pelo An. cruzii, An. oswaldoi e An. fluminensis. Entretanto, Cx. quinquefasciatus foi a ?nica esp?cie verdadeiramente eussinantr?pica.
An. cruzii e Ae. scapularis foram capturadas realizando o repasto sang??neo no intra e peridomic?lio, indicando que ambas as esp?cies, vetoras de agentes etiol?gicos causadores respectivamente de mal?ria e arboviroses em outras localidades no litoral do Estado de S?o Paulo, podem estar envolvidas na transmiss?o domiciliar dessas doen?as.
Excetuando-se as incid?ncias de Tr. digitatum no per?odo noturno, os sabet?neos foram capturados essencialmente nas horas iluminadas do dia. Todos os anofelinos estiveram preferencialmente nas amostragens noturnas e os culic?neos apresentaram esp?cies noturnas: Cx. nigripalpus, Cq. chrysonotum e Cq. venezuelensis; diurnas: Ps. ferox e Ps. albipes; e ecl?ticas quanto a prefer?ncia pelo per?odo de ocorr?ncia: Ae. serratus, Ae. scapularis e Ae. fulvus.
As fases lunares n?o foram determinantes ? incid?ncia da fauna culicideana. Entretanto, as amostragens realizadas em noites de lua nova foram quantitativamente mais proveitosas. Ae. scapularis foi capturado preferencialmente em noites de lua cheia.
