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

Abstract

ABSTRACT. Mosquitos (Diptera, Culicidae) of Pendotiba and oceanic regions of Nite.,ói (Rio de Janeiro, Brazil). Female mosquitoes (Culicidae) were collecled in human bait weekly between March 1997 to February 1998 A statistical analysis between monthly female frequencies and temperature, air humidity and precipitation monthly indices was done, using Sperman correlation in Statistica 4.2 programo The only difference among the collected poinls is lhe higher number of species collected in Engenho do MaIo, in spite of lhe differences between them in relation lO vegeta l formation and conservation. The species showed higher frequencies of females during spring and summer seasons, and permil us to conclude that lemperalure and precipilation demonslraled high leveis of correlation to female frequencies along lhe one year study, but the same was not observed in relation to air humidity. Some of the identified species, such as Aedes aegyp/i, A. a/bopictus, A. scapu/aris, Haemagogus /eucoce/aenus and Cu/ex quinquefasciatus are important as disease vectors and control suggeslions are made in front of lhe relative abundance ofthem in different periods oflhe year. KEY WORDS . Diptera, Culicidae, ecology, Niterói, Rio de Janeiro o Município de Niterói, no Estado do Rio de Janeiro, vem experimentando, desde a década de 80, um acelerado crescimento populacional e econômico, devido não só ao crescimento autóctone, mas também à imigração proveniente do interior do Estado e de outros Municípios da Região Metropolitana do Rio de Janeiro. Esta imigração deve-se aos desequilíbrios na política de desenvolvimento regional, que faz com que o interior fique em desvantagem no processo de evolução econômica e ocasiona crise imobiliária na região metropolitana, resultante do fluxo do contingente humano. A falta de espaço residencial nas áreas mais tradicionais do municí-pio, bem como de outros municípios incluindo a própria capital (Rio de Janeiro),

Survey of Plasmodium in the golden-headed lion tamarin (Leontopithecus chrysomelas) living in urban Atlantic forest in Rio de Janeiro, Brazil

“…Though this study agrees with findings in the literature, which shows animals from the same genus or even from the same family are often negative for infection [ 2 , 9 , 25 , 29 , 30 ], it is still possible that other non-human primates in the area are infected with Plasmodium spp. Data from the website SINAN showed that endemic infections in areas around the park do occur (Table 1 ) and interestingly Anopheles aqualasis, an efficient transmitter of Plasmodium spp., has been identified specifically in the same area where the L. chrysomelas were captured [ 34 ]. In addition, other studies in the Atlantic forest have reported Plasmodium spp.…”
