Resumo

Autochthonous malaria cases in the state of Espirito Santo, Brazil, are distributed in mountainous regions surrounded by the Atlantic Forest. While some aspects of this disease are unclear, detection of possible vector species can help to elucidate epidemiological uncertainties. Entomological and natural infection studies were carried out using anophelines (Diptera: Culicidae) captured in the municipality of Santa Tereza, ES. Monthly captures were made from March 2004 to February 2006. CDC-CO(2) traps were used from dusk (6: 00 P. M.) to dawn (6: 00 A. M.) to capture anophelines in the following habitats: near the houses, in open areas (at ground level) and inside, and at the margins of the forest (canopy and ground level). Shannon light traps were also used at the same locations of the CDC-CO(2) traps. A total of 2,290 anophelines within 10 species were captured. The relative frequency of Anopheles (Kerteszia) cruzii Dyar \& Knab / A. (K.) homunculus Komp was the highest, with the majority captured in CDC-CO(2) traps installed in the forest canopy. The main species captured in Shannon traps was A. (Nyssorhynchus) strodei Root. The largest number of anophelines was captured from July to September and from 6: 00 P. M. to 10: 00 P. M. Anopheles (K.) cruzii is the probable vector for malaria transmission inside or near the Atlantic Forest fragments, but the role of other species cannot be ignored, as 53% of the sampled anophelines belonged to the subgenus Nyssorhynchus. The natural infection of A. cruzii, A. parvus (Chagas) and A. galvaoi Causey, Deane \& Deane by Plasmodium vivax detected by PCR from DNA extracted from their thoraxes supports this view. (AU)
