“…Different situations have been described for other regions of Brazil. In the southeast, the flasks and drains groups were most commonly found to have immature forms of the vector in domiciles in the City of São Paulo, and a similar result was noted for the grease traps in the City of Rio de Janeiro 24,25 . Another study carried out in the north, in Manaus, Amazonas, found that the flasks and tires groups accounted for the largest number of larvae and pupae 17 .…”

INTRODUCTION: Dengue is a serious public health problem worldwide, with cases reported annually in tropical and subtropical regions. Aedes aegypti (Linnaeus, 1762), the main vector of dengue, is a domiciliary species with high dispersal and survival capacities and can use various artificial containers as breeding sites. We assessed potential container breeding sites of A. aegypti in the municipality of Caxias, Maranhão, Brazil. METHODS: In the initial phase, we analyzed 900 properties in 3 neighborhoods during the dry and rainy seasons (August-October 2005 and February-April 2006, respectively). During the second sampling period, September 2006-August 2007, we used 5 assessment cycles for 300 properties in a single neighborhood. RESULTS: During the dry and rainy seasons, water-storage containers comprised 55.7% (n = 1,970) and 48.5% (n = 1,836) of the total containers inspected, and showed the highest productivity of immature A. aegypti; we found 23.7 and 106.1 individuals/container, respectively, in peridomicile sites. In intradomicile sites, water-storage containers were also the most important breeding sites with 86.4% (n = 973) and 85.6% (n = 900) of all containers and a mean of 7.9 and 108.3 individuals/container in the dry and rainy seaso-October 2006 (1,342). The highest number of positives (70) was recorded in May, mostly (94%) in storage containers. CONCLUSIONS: Storage containers are the principal and most productive A. aegypti breeding sites and are a major contributing factor to the maintenance of this vector in Caxias.

“…In spite of the high temperatures at this time of year, the immature forms continue to exploit the large water containers, assuring the continuity of the vector from one season to the next. Other studies have also noted this factor in helping to maintain the vector in the northeast region of the country 24,26,27 .…”

“…Without the presence of the large containers that produce adult mosquitoes, the infestation is associated with the widespread availability of containers with a small volume of water, as found in a study carried out in city of Rio de Janeiro, Southeastern Brazil. 22 It was not possible to identify the most productive property and container types in Jaguare. The strategy of larval and pupal counting to identify the most productive types of containers 4 will not benefi t vector control in locations with characteristics comparable to those found in this neighborhood, as it did in locations in which large containers are present.…”

Aedes aegypti entomological indices in an endemic area for dengue in Sao Paulo State, Brazil

OBJECTIVE:To evaluate the most productive types of properties and containers for Aedes aegypti and the spatial distribution of entomological indices. METHODS:Between December 2006 and February 2007, the vector's immature forms were collected to obtain entomological indices in 9,875 properties in the Jaguare neighborhood of Sao Jose do Rio Preto, SP, Southeastern Brazil. In March and April 2007, a questionnaire about the conditions and characteristics of properties was administered. Logistic regression was used to identify variables associated with the presence of pupae at the properties. Indices calculated per block were combined with a geo-referenced map, and thematic maps of these indices were obtained using statistical interpolation. RESULTS:The properties inspected had the following Ae. aegypti indices: Breteau Index = 18.9, 3.7 larvae and 0.42 pupae per property, 5.2 containers harboring Ae. aegypti per hectare, 100.0 larvae and 11.6 pupae per hectare, and 1.3 larvae and 0.15 pupae per inhabitant. The presence of yards, gardens and animals was associated with the presence of pupae. CONCLUSIONS:Specific types of properties and containers that simultaneously had low frequencies among those positive for the vector and high participation in the productivity of larvae and pupae were not identifi ed. The use of indices including larval and pupal counts does not provide further information beyond that obtained from the traditional Stegomyia indices in locations with characteristics similar to those of São José do Rio Preto. The indices calculated per area were found to be more accurate for the spatial assessment of infestation. The Ae. aegypti infestation levels exhibited extensive spatial variation, indicating that the assessment of infestation in micro areas is needed.

“…Quanto aos números absolutos, a proporção sempre mostra uma disparidade a favor dos artificiais, indicando a ação antrópica é o principal responsável pela dispersão do vetor. Os valores encontrados no presente estudo corroboram dados correlacionados em outras pesquisas, as quais apontam que em meio urbano, o A. aegypti apesar de se reproduzir em depósitos naturais, tem preferido os artificiais (Tabela 3), visto que a concentração demográfica, aliada a falta de infraestrutura e (des)cuidados antrópicos auxiliam demasiadamente no aumento dos números de recipientes artificiais que podem ser utilizados pelo vetor da dengue (SILVA et al, 2006;MENDONÇA & DUTRAM, 2009).…”
