Mosquitoes in artificial containers include Aedes aegypti and the Culex pipiens complex, both recognized worldwide as vectors of diseases. The goal of this study was to characterize mosquito communities in water-filled artificial containers in the islands of one of the major temperate wetlands in South America, and to assess whether A. aegypti is present in the area. Five domestic areas located in the insular Tigre District (Buenos Aires Province, Argentina) were visited monthly between November 2011 and May 2012. A total of 1013 artificial containers (half of themwithwater)were inspected formosquito immatures. 3359 specimens corresponding to seven species were collected in 88 containers. A. aegypti was recorded for the first time in this wetland, and in all land use categories examined from February to May. Among the remaining six species, only Culex dolosus and C. pipiens were highly abundant. 88% of themosquito positive containerswere buckets, dustbins and boats,whereas highly available bottles did not act asmosquito breeding habitats; the key breeding containerwas different for each land use. The Container Index showed differences among land uses, materials, water capacity and volume, and insolation levels. Generalized Linear Mixed Models suggested that the probability of finding mosquitoes was higher for containers located in dumps and recreational areas, made of resin/fiberglass, presenting intermediate water volumes, and not in use if partially or totally shaded but in use for sunlit containers. Recommendations formosquito prevention and control in the islands are proposed.

Field efficacy of triflumuron against Aedes and Culex mosquitoes in temperate Argentina

Aedes aegypti and Culex pipiens s.l. (Linnaeus, 1762 and 1758, respectively) (Diptera: Culicidae) are importantvectors of diseases to humans and a growing public health concern. In order to contribute to the control ofmosquito vectors by low environmental impact approaches we assessed the susceptibility of natural populationsof container-breeding mosquitoes to triflumuron, an insect growth regulator, in temperate Argentina. A field trialwas conducted to evaluate the efficacy of two doses (0.5 ppm and 1 ppm) of triflumuron (SC 48%) againstnatural populations of Ae. aegypti and Culex spp. immatures in flower vases of four cemeteries. The resultsdemonstrated the susceptibility of both target mosquitoes to triflumuron in field conditions. For Ae. aegypti,dose-dependent reductions were achieved in the presence of pupae and the percentage of water-holding containersharbouring L3–4 and/or pupae, whereas the larvae abundance was equally reduced for both doses. ForCulex spp., similar levels of reduction of larvae abundance and pupae presence were achieved with both doses. Significant effects on the response variables measured were recorded up to six to eight weeks post-intervention. Bimonthly applying 1 ppm triflumuron in the context of an integrated mosquito management should achieve alasting control of Ae. aegypti and Culex spp. in small artificial containers with minimal environmental impacts.
