Data on frequency and seasonal distribution of culicinae were
recorded in the forest near a recently constructed
hydroelectric plant - Samuel, in the State of Rondonia,
Brazilian Amazon. Collections were performed almost daily
from August 1990 to July 1991, between 6 and 9 p.m., using
human bait. A total of 3,769 mosquitoes was collected,
representing 21 species, including seven new records for the
State of Rondonia. The most frequently collected species were
Aedes fulvus (25%) and Ae. pennai (12.3%). The
highest density for the majority of mosquito species coincided
with the rainy season.
