A study of crepuscular and night-biting mosquitoes was conducted at remote settlements along the Padauiri River, middle Negro River, state of Amazonas, Brazil. Collections were performed with human bait and a CDC-light trap on three consecutive days per month from June 2003-May 2004. In total, 1,203 h of collection were performed, of which 384 were outside and 819 were inside houses. At total of 11,612 specimens were captured, and Anophelinae (6.01%) were much less frequent than Culicinae (93.94%).
Anopheles darlingi
was the most frequent Anophelinae collected. Among the culicines, 2,666
Culex (Ae.)
clastrieri
Casal & Garcia, 2,394
Culex. (Mel.) vomerifer Komp, and 1,252
Culex (Mel.) eastor Dyar were the most frequent species collected. The diversity of insects found reveals the receptivity of the area towards a variety of diseases facilitated by the presence of vectors involved in the transmission of
Plasmodium
, arboviruses and other infectious agents.
