Mosquitos (Diptera, Culicidae) das regiões de Pendotiba e oceânica de Niterói (Rio de Janeiro, Brasil)

Abstract

A statistical analysis between monthly female frequencies and temperature, air humidity and precipitation monthly índices was done, using Sperman correlation in Statistica 4.2 program. Female mosquitoes (Culicidae) were collected weekly in human bait, during the period from March 1997 to February 1998, in three different areas of the oceanic region of Niterói city, Rio de Janeiro State, in southeaster coast of Brazil. The results indicated the presence of l6 specics: Anophe/es aquasalis, Aedes scapularis, A. taeniurhynchus, A. albopictus, A. aegypti, Haemagogus leucocelaenus, Psorophora ferox, P. conffinis, P. cingulata, Culex quinquefasciatus, C. nigripalpus, Coquillettidia venezuelensis, Uranotaenia calosomata, Limatus durhami, Weyomyia oblita and Phoniomyia sp, species. The only difference among collected points is the higher number of species collected in Engenho do Mato, in spite of the differences between them in relation to vegetal formation and conservation. The species showed higher frequencies of females during spring and summer seasons, and permit us to conclude that temperature and precipitation demonstrated high leveis of correlation to female frequencies along the one year study, but the sarne was not observed in relation to air humidity. Some of the identified species of Culicidae, such as Aedes aegypti, Aedes albopictus, Aedes scapularis, Haemagogus leucocelaenus and Cu/ex quinquefasciatus are. important disease vectors and therefore control suggestions are proposed considering the relative abundance of these species in different seasons of the year.
