“…The variables found to be most contributing to the breeding site distribution are consistent with results reported by Porcasi et al (2012) and Rotela et al (2012) for other cities in northern Argentina. However, the findings are in contrast to findings by Vezzani et al (2005) for microhabitat suitability in the southern latitudes, e.g. Buenos Aires, a fact that reinforces the results obtained here taking into account that one of the key aspects to reduce the abundance of the vector involves the identification of Ae.…”

The main objective of this study was to obtain and analyse the space-time dynamics of Aedes aegypti breeding sites in Clorinda City, Formosa Province, Argentina coupled with landscape analysis using the maximum entropy approach in order to generate a dengue vector niche model. In urban areas, without vector control activities, 12 entomologic (larval) samplings were performed during three years (October 2011 to October 2014). The entomologic surveillance area represented 16,511 houses. Predictive models for Aedes distribution were developed using vector breeding abundance data, density analysis, clustering and geoprocessing techniques coupled with Earth observation satellite data. The spatial analysis showed a vector spatial distribution pattern with clusters of high density in the central region of Clorinda with a well-defined high-risk area in the western part of the city. It also showed a differential temporal behaviour among different areas, which could have implications for risk models and control strategies at the urban scale. The niche model obtained for Ae. aegypti, based on only one year of field data, showed that 85.8% of the distribution of breeding sites is explained by the percentage of water supply (48.2%), urban distribution (33.2%), and the percentage of urban coverage (4.4%). The consequences for the development of control strategies are discussed with reference to the results obtained using distribution maps based on environmental variables.

“…A positive association was also found between oviposition and industrial sites, possibly due to a high density of water containers. Vezzani et al (2005) also found that, in Buenos Aires, the microhabitats most favourable for reproduction of Ae. aegypti were sites less exposed to sunlight, such as shaded and vegetated neighbourhoods, these environments are also frequent in the neighbourhoods sampled in Córdoba.…”

“…A similar trend was previously reported in flower vases within the study area (Vezzani & Albicócco 2009) and there is general consensus that there are higher frequencies of containers harbouring Ae. aegypti in shaded habitats (e.g., Focks et al 1981, Kittayapong & Strickman 1993, Vezzani et al 2005, Barrera et al 2006). This trend was consistent along the three urbanisation levels, but statistical comparisons suggest that it was less marked within small localities.…”

“…Within the Federal District, the spatial pattern of Ae. aegypti oviposition was associated with an urbanisation gradient (Carbajo et al 2006) and the presence of immatures at the microhabitat scale was related to shaded and vegetated surroundings (Vezzani et al 2005). However, these studies were restricted to highly urbanised areas and the knowledge of both mosquito vectors in small towns, as well as in used tires, is truly limited in the region.…”

Used vehicle tires are a source of mosquito vectors and a means of their introduction and expansion. With the aim of assessing the effects of urbanisation on the main mosquito vectors in temperate Argentina, the infestation levels of Aedes aegypti (L.) and Culex pipiens L. were studied in used tires from highly urbanised cities to low-urbanised small towns in Buenos Aires. Immatures of both species accounted for 96% of the 9,722 individuals collected; the total individuals collected represented seven species. The percentage of water-filled tires containing mosquitoes [container index (CI)] was 33% and the percentage of infested sites [site index (SI)] was 65.2%. These indexes decreased significantly from low to high urbanisation levels for both mosquito species. The relative abundance (RA) of Ae. aegypti immatures was slightly higher toward large cities, but showed no difference for Cx. pipiens. The CI of shaded tires was significantly higher than the CI of exposed tires for both mosquito species. There was no difference in RA values between shaded and sunlit tires. The CI and the SI were highest during the summer across the urbanisation levels, except for Cx. pipiens, which continued to increase during the autumn in small towns. Results related to urbanisation gradient, sunlit exposure and seasonality are discussed
