“…In contrast, a single container type was found to produce >75% of immatures on vacant lots (tires) and in parking lots (flower pots). The importance of tires for production of mosquitoes in non-residential settings in Latin America was noted previously (Lopes et al 1993, Morrison et al 2006, Rubio et al 2011). We also found greater abundance of Ae.…”

We assessed the potential for vacant lots and other non-residential settings to serve as source environments for Aedes (Stegomyia) aegypti (L.) in Mérida City, México. Mosquito immatures were collected, during November 2011 – June 2013, from residential premises (n = 156 site visits) and non-residential settings represented by vacant lots (50), parking lots (18), and streets/sidewalks (28). Collections totaled 46,025 mosquito immatures of 13 species. Ae. aegypti was the most commonly encountered species accounting for 81.0% of total immatures, followed by Culex quinquefasciatus Say (12.1%). Site visits to vacant lots (74.0%) were more likely to result in collection of Ae. aegypti immatures that residential premises (35.9%). Tires accounted for 75.5% of Ae. aegypti immatures collected from vacant lots. Our data suggest that vacant lots should be considered for inclusion in mosquito surveillance and control efforts in Mérida City, as they often are located near homes, commonly have abundant vegetation, and frequently harbor accumulations of small and large discarded water-holding containers that we now have demonstrated to serve as development sites for immature mosquitoes. Additionally, we present data for associations of immature production with various container characteristics, such as storage capacity, water quality and physical location in the environment.

“…This agrees with results of previous studies from Mérida (Garcia-Rejon et al 2008, 2011a; Manrique-Saide et al 2008, 2012, 2013) and underscores the importance of controlling mosquitoes in larval habitats. Highdiversity of species in tires also was reported from Argentina (Rubio et al 2011). In addition to containers on residential premises and storm-water drains/catch basins along streets/ sidewalks, our data indicated that containers in vacant lots are productive mosquito habitats in Mérida City.…”

We examined the species composition and temporal occurrence of immature mosquitoes in containers and storm-water drains/catch basins from November 2011 to June 2013 in Mérida City, México. A wide range of urban settings were examined, including residential premises, vacant lots, parking lots, and streets or sidewalks with storm-water drains/catch basins. In total, 111,776 specimens of 15 species were recorded. The most commonly collected species were Aedes (Stegomyia) aegypti (L.) (n = 60,961) and Culex quinquefasciatus Say (45,702), which together accounted for 95.4% of the immatures collected. These species were commonly encountered during both rainy and dry seasons, whereas most other mosquito species were collected primarily during the rainy season. Other species collected were Aedes (Howardina) cozumelensis Diaz Najera, Aedes (Ochlerotatus) taeniorhynchus (Wiedemann), Aedes (Ochlerotatus) trivittatus (Coquillett), Culex coronator Dyar and Knab, Culex interrogator Dyar and Knab, Culex lactator Dyar and Knab, Culex nigripalpus Theobald, Culex salinarius Coquillett, Culex tarsalis Coquillett, Culex thriambus Dyar, Haemagogus equinus Theobald, Limatus durhamii Theobald, and Toxorhynchites rutilus (Coquillett). The greatest number of species was recorded from vacant lots (n = 11), followed by storm-water drains/catch basins (nine) and residential premises (six). Our study demonstrated that the heterogeneous urban environment in Mérida City supports a wide range of mosquito species, many of which are nuisance biters of humans and/or capable of serving as vectors of pathogens affecting humans or domestic animals. We also briefly reviewed the medical importance of the encountered mosquito species.

“…Linnaeus, 1758 (Diptera: Culicidae), hereby referred to as the Pipiens Assemblage following Harbach (2012), represent the most important Culex species from a medical and veterinary standpoint because they are vectors of multiple pathogens affecting humans, domestic and wild animals (reviewed in Vinogradova 2000). In Argentina, these mosquitoes have been recently implicated as vectors of St. Louis encephalitis virus, West Nile virus and dirofilariasis (Rubio et al 2011, Vezzani et al 2011). Since there is no treatment or vaccine against most of these diseases, entomological surveillance and mosquito control remain as the main public health strategies.…”

“…In Buenos Aires, it is the most abundant mosquito in artificial containers (Vezzani & Albicócco 2009, Rubio et al 2011) and one of the three most abundant in premises (Vezzani et al 2011). It has also been collected in a wide variety of larval habitats in wild recreational areas located close to the metropolitan area (Albicócco et al 2011, Cardo et al 2011), in which the abundance of migratory birds contribute to the risk of entry of different arboviruses to the region.…”

Given their medical and veterinary relevance, the members of the Pipiens Assemblage are a worldwide target of ecological research. The distribution of Culex pipiens s.s. and Cx. quinquefasciatus converge in Buenos Aires, Argentina, where hybrids have been detected. Each member of the assemblage exhibits a distinct eco-physiological behaviour that can affect its efficiency in pathogen transmission. Our aim was to identify the environmental drivers for the spatio-temporal distribution of each member, focusing on latitudinal and urbanisation gradients. Immatures of mosquitoes were surveyed in artificial containers found within 11 public cemeteries, raised up to the adult stage and identified by their male genitalia. The distribution of each member was associated with the environment in a Generalized Linear Model. The variable accounting for most of the heterogeneity was latitude; Cx. quinquefasciatus was collected more frequently at northern cemeteries, whereas Cx. pipiens and hybrids were more likely at the southern extreme. The urbanisation gradient was also associated with the occurrence of Cx. quinquefasciatus and hybrids at the high and low end, respectively. Other relevant variables were cemetery total area, the proportion with graves and the presence of plastic flowers in the containers. The spatial distribution of the members of the Pipiens Assemblage within the sympatric region in South America is driven by environmental features. The information presented herein provides essential baseline data for surveillance programs and control activities.
