The presence of West Nile (WNV) and dengue viruses and the lack of recent mosquito surveys in Puerto Rico prompted an investigation on the distribution and abundance of potential arbovirus vectors in the San Juan Metropolitan Area, and their variation with seasons and habitats. We sampled mosquitoes in early and late 2005 in 58 sites from forests, nonforest vegetation, wetlands, and high- and low-density housing areas using ovijars, Centers for Disease Control and Prevention miniature light/CO2 traps, and gravid traps. A total of 28 mosquito species was found. San Juan had potential WNV enzooticvectors (Culex nigripalpus) within and around the city in wetlands and forests, but few were captured in residential areas. A potential WNV bridge vector (Cx. quinquefasciatus) was abundant in urbanized areas, and it was positively correlated with the main dengue vector, Aedes aegypti. High-density housing areas harbored more Ae. aegypti. Container mosquitoes, including Aedes mediovittatus, were more abundant during the climax of the rainy season when most dengue occurs in Puerto Rico. The greatest risk for contracting WNV would be visiting forests and swamps at night. Culex (Culex) and Culex (Melanoconion) mosquito species were more abundant during the transition dry-wet seasons (March-May).

“…Also, in the United States, this mosquito has been incriminated as the vector of the eastern equine encephalitis virus (Ortiz et al, 2003) and as potential vector of West Nile encephalitis (Hribar et al, 2003). This insect has a wide geographical distribution on the American continent particularly along the coasts; on the Atlantic coast, it is distributed from Massachusetts in the United States to Santa Catarina in south Brazil, and on the Pacific coast from California to Peru (Forattini, 1965).…”

ABSTRACT. In Colombia, the mosquito Ochlerotatus taeniorhynchus has been identified as an efficient vector of the epidemic-epizootic Venezuelan equine encephalitis virus. We evaluated the genetic variability and heterogeneity of this mosquito in Colombian populations using eight microsatellite DNA loci. Two hundred and ten mosquito specimens collected from seven populations of the Colombian Atlantic coast (San Bernardo del Viento, Coveñas, Cartagena, Barranquilla, Ciénaga, Dibulla, and Riohacha) were analyzed. We found five polymorphic microsatellite loci, with 19 alleles giving 62.5% polymorphism; the mean number of alleles per locus was 3.8. The mean expected heterogeneity ranged from 0.568 to 0.660. Most of the polymorphic microsatellite loci were in Hardy-Weinberg disequilibrium, due to both deficit and excess of heterozygotes. The Fst statistic gave a total value of 0.0369, reflecting low genetic differentiation among the populations and, as a consequence, a low degree of structuring among them, while gene flow was high (Nm = 6.52); these findings point to genetic homogeneity among these populations. There was no significant linkage disequilibrium between genotype pairs of the various populations. We concluded that this mosquito is distributed in local populations along the Colombian Atlantic coast; these findings will be useful for developing strategies for controlling this vector.
