Determination of the composition and activity of Culicidae mosquitoes by the use of the CDC trap in the Ribeira Valley, S. Paulo State, Brazil

Using a CDC light-trap, the specific fauna composition of mosquitoes Culicidae was determined at places with primary vegetation of lowlands near swampy areas along the Southern coast of S. Paulo State, Brazil. As a result, about 64 species or groups were found. Among the more frequent ones, Culex (M...

Sumario:Using a CDC light-trap, the specific fauna composition of mosquitoes Culicidae was determined at places with primary vegetation of lowlands near swampy areas along the Southern coast of S. Paulo State, Brazil. As a result, about 64 species or groups were found. Among the more frequent ones, Culex (Mel.) sacchettae (71.6%), Anopheles (Ker.) cruzii (10.5%), Phoniomiya spp. (8.2%) and Culex (Mel.) taeniopus (2.9%) were outstanding. Also by the use of this method of capture, with fowls and rodents as animal bait, in vespertine dusk and night periods, the Cx. sacchettae showed a clear dominance, which was the opposite of what occured at the same places, using human bait, when An. cruzii was the predominant species. Ranging from 1.7 to 6.2, the diversity estimated for inland, edge forest, open field and residential areas showed a relatively rich fauna of Culicidae. Despite the marked presence of Culex (Cux.) quinquefasciatus in domiciliary area, the high frequence of Cx. sacchettae was rather unexpected. Moreover, the proportional presence of An. cruzii, both on the ground and in forest canopy suggests the mobility of this anophelinae inside the wood, while its activity in extraforest environments has revealed itself to be very restricted. In this particular case, Cx. sacchettae has shown itself as the most ubiquitons and frequently occurring species throughout the year, although its higher density peaks occur in summer and autumn.
