“…On the other hand, in well‐planned urban areas, Aedes aegypti breeds in various indoor habitats such as plant pots, bamboo pole holders, and tanks of air conditioners (Goh, ; Hammond et al, ; Halstead, ). Further, there is growing evidence for vector adaptation to outdoor breeding habitats (Chadee & Martinez, ; Manrique‐Saide et al, ) or seasonal shifts between rain‐fed and human‐made containers in urban areas (Becker et al, ). The outdoor breeding habitats in urban settings include roof gutters, discarded receptacles, sewage, and storm drainage networks (Barrera et al, ; Manrique‐Saide et al, ; Montgomery et al, ; Montgomery & Ritchie, ).…”

Dengue is the most important human arboviral disease in Singapore. We classified residential areas into low‐rise and high‐rise housing and investigated the influence of urban drainage on the distribution of dengue incidence and outdoor breeding at neighborhood and country scales. In Geylang area (August 2014 to August 2015), dengue incidence was higher in a subarea of low‐rise housing compared to high‐rise one, averaging 26.7 (standard error, SE = 4.83) versus 2.43 (SE = 0.67) per 1,000 people. Outdoor breeding drains of Aedes aegypti have clustered in the low‐rise housing subarea. The pupal density per population was higher in the low‐rise blocks versus high‐rise ones, 246 (SE = 69.08) and 35.4 (SE = 25.49) per 1,000 people, respectively. The density of urban drainage network in the low‐rise blocks is double that in the high‐rise ones, averaging 0.05 (SE = 0.0032) versus 0.025 (SE = 0.00245) per meter. Further, a holistic analysis at a country‐scale has confirmed the role of urban hydrology in shaping dengue distribution in Singapore. Dengue incidence (2013–2015) is proportional to the fractions of the area (or population) of low‐rise housing. The drainage density in low‐rise housing is 4 times that corresponding estimate in high‐rise areas, 2.59 and 0.68 per meter, respectively. Public housing in agglomerations of high‐rise buildings could have a positive impact on dengue if this urban planning comes at the expense of low‐rise housing. City planners in endemic regions should consider the density of drainage networks for both the prevention of flooding and the breeding of mosquitoes.

“…aegypti life‐history studies and on the current evidence, it is clear that females can occasionally survive long periods of over 200 days and commonly in the laboratory over 150 days, and can serve as reservoirs of arboviruses within communities. These findings provide some insights into the role that old females can play in the transmission of dengue, chikungunya, and Zika viruses, with females possibly taking over 20 blood meals and may be classified as ‘super‐infectors or super‐transmitters.’ This may modify epidemiological patterns in this region as recently hypothesized by Chadee and Martinez ().…”

“…The finding of overwintering populations of Ae. aegypti in subterranean habitats on Capitol Hill, Washington, DC neighborhoods (Lima et al ) and in underground drains, sewers, and pit latrines in the Caribbean and Latin American regions (Chadee and Martinez ) provide further evidence that mosquitoes can survive drought and severe or extreme events which may occur throughout the year. These old females also provide evidence that both females and males can survive for long periods, albeit in small numbers, allowing genotypic analysis similar to those conducted by Joy et al ().…”

Few laboratory and field studies have reported long survival periods for Ae. aegypti females and even fewer have designed experiments to characterize this important life history trait. This study was conducted under laboratory conditions to determine the number of blood meals taken by individual females, the number of eggs laid per individual female, the length of the gonotrophic cycle, and the duration of female survival. The results showed individual females oviposited between 670 and 1,500 eggs throughout their lifetimes, females undergoing large numbers of gonotrophic cycles and surviving up to 224 days. These results are discussed in the context of vector competence, unique alternating high and low oviposition patterns observed after week 14, and resource partitioning/allocation by older Ae. aegypti females after blood feeding.

“…A melhoria das condições higiênico-sanitárias das habitações, coleta apropriada do lixo e fornecimento de água encanada são medidas também importantes no controle da dengue. Ademais, estudos em diferentes latitudes, temperaturas, condições ambientais e sanitárias que visem ao monitoramento dos vetores transmissores dos vírus da dengue tornam-se ferramentas importantes para a melhoria dos programas de controle, uma vez que o controle vetorial é o único método de prevenir epidemias da dengue [27][28][29][30][31] . ▄ AGRADECIMENTOS À Secretaria Municipal de Saúde de Picos, pela gentileza em fornecer os dados para realização desta pesquisa.…”

Resumo Dois terços da população mundial vivem em áreas infestadas com mosquitos vetores da dengue, especialmente o Aedes aegypti. Este estudo realizou um levantamento de dados sobre casos de dengue no município de Picos, no Estado do Piauí, Brasil, entre os anos de 2007 e 2011, enfatizando alguns fatores envolvidos em sua transmissão. Os dados foram coletados no Centro de Zoonoses de Picos da Secretaria Municipal de Saúde e no Sistema de Informação da Febre Amarela e Dengue (SISFAD) do Programa Nacional do Controle da Dengue (PNCD). Durante os anos de 2007, 2008, 2009, 2010 e 2011, foram visitados, respectivamente, 116.301, 182.024, 181.892, 187.619 e 195.377 imóveis pelos agentes de controle de endemias (ACE). As residências foram os estabelecimentos com maior positividade para focos de larvas de Aedes aegypti (p<0,05). Dentre os depósitos inspecionados, as larvas predominaram em armazenadores de água rebaixados (tambores) e elevados (caixas-d’água). Testes sorológicos confirmaram um total de 85 casos em 2007, 117 em 2008, 221 em 2009, 296 em 2010 e 217 em 2011. A média de casos foi mais expressiva em pacientes com idade entre 20-34 anos (p<0,05). No ano de 2011, foram identificados, pela primeira vez, focos de Aedes albopictus, encontrados principalmente em tambores de água. Portanto, o número de casos vem aumentando, o que sugere que o controle vetorial da transmissão pode sofrer forte impacto a partir da ação de vigilância epidemiológica em âmbito coletivo, uma vez que depósitos de água peri ou intradomiciliares representaram os locais predominantes para a procriação de vetores.
