Abstract

We present the results of anopheline captures in Belém, Pará, Brazil, from 1995-2004, and a comparison with captures from 1930-1999. In the earlier period, 20 species were identified: Anopheles albitarsis s.l., An. aquasalis, An. argyritarsis, An. braziliensis, An. darlingi, An. eiseni, An. evansae, An. galvaoi, An. intermedius, An. kompi, An. mediopunctatus, An. nimbus, An. nuneztovari, An. oswaldoi, An. peryassui, An. punctimacula, An. shannoni, An. strodei, An. thomasi, and An. triannulatus. Seven of these species were not found in 1995-2004 (An. argyritarsis, An. eiseni, An. galvaoi, An. kompi, An. nimbus, An. punctimacula, and An. thomasi). The persistence of so many species is probably due to the local preservation of forest areas. Two species are of vectorial importance (An. darlingi and An. aquasalis). An. aquasalis is still the most abundant species (46.26% of adults, 99.21% of larvae) and the only one detected in all capture sites. There is thus a potential risk of malaria transmission in the entire municipality of Belém.
