From October 1995 to January 1996 a survey of the culicid species mentioned above was carried out in a restrict Atlantic Forest area, located in the Marumbi mountain (approximately 6,5 km from the town of Morretes). Shannon light trap was used during 48 nights, in the four lunar phases: full moon, first quarter, new moon and last quarter between evening and morning twilights. A total of 594 Coquillettidia (Rhynchotaenia) venezuelensis (Theobald, 1912) specimens were collected and the different night flight activity in the four moon phases was observed. Regarding the hourly activity, the peak higher numbers of Coquillettidia venezuelensis were collected in the first three hours. Concerning the environmental factors, temperature was found to be the more relevant one for the flight activity of Coquillettidia venezuelensis.

From October 1995 to January 1996 Aedes (Ochlerotatus) scapularis (Rondani, 1948) was studied in a small area of the Atlantic Forest, Serra do Marumbi, Morretes, Paraná, Brazil. Adults were captured with Shannon light traps for 48 nights, representing 12 nights for seven time intervals. Traps were operated from dusk to dawn. The influences on flight activity of the lunar phase, ambient temperature, relative humidity, and rainfall were analyzed. Ae. scapularis had a flight behaviour different in each of the four lunar phases. In relation to flight period, the species showed higher activity during the first three lunar intervals. Among the climatic variables, temperature and relative humidity positively influenced flight activity during the night.
