BackgroundThis study focused on the distribution and abundance of the eggs of Aedes aegypti and Aedes albopictus.MethodsEighty ovitraps were exposed for four days of each month in peri- and intradomiciliary environments of 40 urban residences on 20 street blocks that were drawn monthly in Sebastião, SP, between February 2011 and February 2012. The monthly distribution of positive ovitrap indices (POI) and mean egg counts per trap (MET) of Ae. aegypti and Ae. albopictus were analyzed using the Kruskal-Wallis test, followed by the Dwass-Steel-Critchlow-Fligner (DSCF) test. Spearman's rank correlation coefficient and simple linear regression were used to determine the association between the meteorological variables of temperature and rainfall and the number of ovitraps with eggs and the egg count.ResultsThe POI and MET of Ae. aegypti were higher in peridomiciliary premises. A positive correlation was found between the temperature and the number of ovitraps with eggs and the egg count of this species in domestic environments. There was no difference in the POI and MET of Ae. albopictus between the environments. A positive correlation was found between temperature and positive ovitraps of Ae. albopictus in peridomiciliary premises. The POI and MET of Ae. aegypti were higher than those of Ae. albopictus.ConclusionsPeridomiciliary premises were the preferred environments for oviposition of Ae. aegypti. The use of ovitraps for surveillance and vector control is reiterated.

BackgroundThe reintroduction of sylvatic yellow fever in the state of São Paulo after about six decades was confirmed in the Northwestern region in 2000, where in 2008 there also occurred an important epizootic. The purpose of this study was to investigate the feeding habits of culicids potentially involved in the sylvatic transmission of the virus in this region.MethodsSpecimens were collected in 24 forested localities at ground level with hand nets and mouth aspirators. Collections were made quarterly between October 2006 and July 2008 during daylight hours. Blood-meal identification was carried out in mosquitoes of the tribes Aedini, Mansoniini and Sabethini. The biotin/avidin sandwich ELISA was employed to determine six source types: bird, bovine, equine, rat, human and monkey.ResultsA total of 24,879 females of the three tribes were obtained, 245 (0.98%) of which were engorged. The presence of three different blood sources per engorged female was the predominant situation, and included 35.10% of the total of samples processed. Samples with two or four different sources were represented by 25.31% and 25.71%, of the specimens, respectively, while just 9.39% had only one type and 1.22%, five different sources. Aedes scapularis, Ae. serratus (Group), Psorophora albigenu and Ps. ferox were the most abundant species and accounted for about 95% of the engorged specimens. Of the principal vector species, Haemagogus janthinomys/capricornii was found with bird, bovine and primate blood. These sources were predominant and alternated top ranking as the most frequent source according to the mosquito species and collection site. In general, primate blood was the most prevalent source.ConclusionsThe human population of the region visits this ecotone frequently, which indicates the need for the periodical assessment of vaccination coverage against yellow fever. The frequency of non-human primate blood source in mosquito species that show minor vector importance in yellow fever virus transmission deserves attention. The eclectic feeding habits and some aspects of the interactions between potential vectors and reservoirs of yellow fever may be associated with the habitat fragmentation characteristic of the region. We recommend that further studies on the capacity and vector competence be performed on secondary vectors in extra-Amazonian region.Electronic supplementary materialThe online version of this article (doi:10.1186/s40409-015-0005-z) contains supplementary material, which is available to authorized users.

A partir de então, tem sido responsável pela transmissão dos vírus dengue em epidemias registradas no território brasileiro desde o início dos anos 1980 1 . Atualmente, o Aedes aegypti encontra-se disseminado em todos os Estados da Federação, onde suas populações apresentam elevada susceptibilidade à infecção natural pelos vírus dengue e da febre amarela 2,3 .…”

RESUMOIntrodução: Desde seu registro, em 2005, no município de Fortaleza, o Aedes albopictus tem exibido uma rápida dispersão. Um estudo visando à identificação das áreas de sua ocorrência, os seus criadouros e a associação com Aedes aegypti e outros culicídeos foi realizado durante o ano de 2008. Métodos: Foram coletadas, de janeiro a julho de 2008, amostras de formas imaturas de culicídeos provenientes de imóveis situados nos bairros de Fortaleza, ressaltando-se algumas características dos criadouros, tais como localização (intradomicílio ou peridomicílio), presença de cobertura (proteção contra a incidência de raios solares e chuva), turbidez da água (água límpida e não límpida), material constituinte, volume, altura em relação ao nível do solo e presença simultânea de diferentes espécies de culicídeos no mesmo criadouro. Resultados: A localização no intradomicílio foi um fator importante para os criadouros do Aedes albopictus [RP=0,52 IC95% (0,33-0,81)], por outro lado, a turbidez da água e a cobertura do depósito não se mostraram como diferenciadores para a infestação [p>0,05]. Para o Aedes aegypti a ausência de turbidez da água foi significativa para a infestação nos criadouros [RP=1,14 IC95% (1,06-1,22)]. Conclusões: a ausência de uma das espécies nos criadouros favorecia sua infestação por outra; criadouros não infestados por Aedes albopictus tinham uma prevalência de infestação de 2,05 [IC95%1,72-2,44] vezes maior pelo Aedes aegypti. Não houve associação significativa entre volume e altura do criadouro e infestação por ambas as espécies. As duas espécies encontram-se dispersas por todo o município, ocupando os mais diversos tipos de criadouros. No entanto, pode-se identificar uma ligeira separação física, com uma infestação maior do Aedes albopictus no peridomicílio. On the other hand, water turbidity and reservoir covering were not shown to be differentiators regarding infestation [p > 0.05]. Absence of water turbidity was significant for Aedes aegypti infestation in breeding sites [PR = 1.14; 95% CI: 1.06-1.22]. Conclusions: Absence of one of the species from the breeding sites enhanced the infestation by another species. Breeding sites that had not been infested by Aedes albopictus had a prevalence of infestation by Aedes aegypti that was 2.05 times greater [95% CI: 1.72-2.44]. There was no significant association between volume and height of the breeding sites and infestation by both species. Both species were found to be dispersed throughout the municipality, occupying a wide diversity of breeding sites. However, a slight physical separation could be identified, with higher infestation with Aedes albopictus outdoors. Palavras
