“…It is important to emphasize that studies seeking to identify and quantify the detritus deposited in the breeding sites during the collections, which serve as food source for the larvae, may contribute to more robust analyses of ecological interactions among mosquitoes and their population dynamics. The similarity in the use of oviposition sites in the urban area of Santa Barbara d'Oeste, São Paulo state has already been described by Piovezan et al , who found similar occupation patterns. The other species were randomly distributed in the area, occurring at low frequencies in the collections, probably due to the sampling methods used in this study.…”

“…Aedes aegypti was the second most frequent species. Although its presence in the urban area of the city of Santa Bárbara d'Oeste has already been well described (Piovezan et al ), other authors indicate infestations in rural areas (Silva ; Barbosa et al ), making this fact of extreme importance to local health authorities, because of the risk of dengue transmission and possible yellow fever urbanization (Consoli and Oliveira ).…”

Because of the high adaptive capacity of mosquitoes, studies that focus on transitional environments become very important, such as those in rural areas, which are considered as bridges between wild diseases and human populations of urban areas. In this study, a survey of the existing species of mosquitoes was performed in an Atlantic Forest area of the city of Santa Bárbara d'Oeste, São Paulo state, Brazil, using traps for immatures and analyzing the frequency and distribution of these insects over the sampling months. Five mosquito species were found: Aedes albopictus (the most frequent species), Aedes aegypti, Aedes fluviatilis, Culex quinquefasciatus, and Toxorhynchites theobaldi. The 4,524 eggs collected in ovitraps showed the presence of the tribe Aedini. Aedes aegypti and Ae. albopictus were identified after larval hatching in the laboratory, with different spatial distributions: the first of which coincides with the area of greatest diversity calculated using the Simpson index, while the second does not. The association of ecological analysis of spatial diversity with simple methods of data collection enables the identification of possible epidemiological risk situations and is a strategy that may be implemented to monitor ecological processes resulting from the interaction among different species of mosquitoes.

“…Mosquitoes of the Psorophora genus were the most abundant Aedini after Ae. scapularis ; this might be explained by the fact that these types of mosquitoes share the same breeding habitats 3 , 19 , 25 . Although Psorophora have been found to carry some types of infection in nature, mosquitoes of this genus are not considered epidemiologically significant vectors.…”

In Brazil, most studies of the Culicidae family are concentrated in rainforest regions. As such, there is a lack of knowledge regarding the diversity of Culicidae in regions with different climatic and vegetational characteristics. The aim of this study was to compile an inventory of Culicidae in protected areas of the semi-arid region of the state of Minas Gerais, Brazil, in order to better understand the diversity of the family within this region. The study was conducted across four protected areas in the northern region of the state, in tropical dry forest (TDF) fragments. Sampling methods included Shannon trap and CDC light trap, as well as active collection. A total of 11,219 mosquito specimens were collected between August 2008 and July 2012, belonging to 11 genera and 45 species; 15 new records for the state of Minas Gerais were registered, as well as 26 new records for semi-arid regions within the state. The high number of new Culicidae records in this region demonstrates the importance of inventory studies for increasing the knowledge of culicid biodiversity in Minas Gerais, and in particular within semi-arid regions of the state.

ABSTRACT:Human modification of the natural environment continues to create habitats in which vectors of a wide variety of human and animal pathogens (such as Plasmodium, Aedes aegypti, Arenavirus etc.) thrive if unabated with an enormous potential to negatively affect public health. Typical examples of these modifications include impoundments, dams, irrigation systems, landfills and so on that provide enabled environment for the transmission of Hemorrhagic fever such as malaria, dengue, avian flu, Lassa fever etc. Furthermore, contemporary urban dwelling pattern appears to be associated with the prevalence of Hemorrhagic diseases in recent years. These observations are not peculiar to the developing world, as urban expansion also contributes significantly to mosquito and other vectors habitats. This habitats offer breeding ground to some vector virus populations. The key to disease control is developing an understanding of the contribution of human landscape modification to vector-borne pathogen transmission and how a balance may be achieved between human development, public health, and responsible urban land use. A comprehensive review of urban land use Pattern Analysis for Hemorrhagic fever risk has been conducted in this paper. The study found that most of the available literatures dwell more on the impact of urban land use on malaria and dengue fevers; however, studies are yet to be found discussing the implications of urban land use on the risk of Ebola, Lassa and other non-mosquito borne VHFs. A relational model for investigating the influence of urban land use change pattern on the risk of Hemorrhagic fever has been proposed in this study. INTRODUCTIONUrban environment support high concentration of human, domestic pet, and introduced animals that create favourable conditions for the transmission of infectious parasite, such as the Hemorrhagic viruses. The rate of transmission of the parasite increases with the quest for speedy urbanization. Again, the actual process of rapid urbanization is associated with various ecological, social, and economic changes, in both the urban area, and the adjacent natural environment. Consequently, the continuous degradation of the ecosystem poses a threat to the present and future dwelling sustainability. Babanyara et al. (2010) observed that rapid population growth and urbanization were of great concern to the sustainability of cities; therefore, the more people on the earth, the greater the impact on the environment and the resources. Also, literature affirms that urbanization takes place in both developed and developing countries (Al-shalabi et al., 2013). However, speedy urbanization, especially the urban land expansion, and the associated problem of unemployment, poverty, poor sanitary condition and environment degradation pose a formidable challenge in some developing countries (Basnet, 2011;Hove et al., 2013;owoeye and ogundiran, 2014). Be that as it may, the developing countries lack adequate implementation policies to address dwelling and Hemorrhagic risks as a re...
