Vector Mosquitoes in the Metropolitan Zone of Mexico Valley and Other Urban/Semi-urban Areas of State of Mexico: Forthcoming Threat?

The Metropolitan Zone of Mexico Valley (MZMV) in Central Mexico includes the states of Hidalgo, Mexico City, and Mexico. The MZMV is the third most populated area in the OECD. The area is free of vector-borne diseases, and information on vector mosquitoes in the MZMV area in the State of Mexico has not been reported. This study reports mosquito species in the MZMV-State of Mexico from 8 years of larval collection and ovitraps. Species collected in areas not in the MZMV of the State of Mexico are also reported. In the MZMV-State of Mexico, 11,484 mosquitoes from eight species were identified: Ae. aegypti (L.), Ae. albopictus (Skuse), Ae. epactius (Dyar and Knab), Cx. quinquefasciatus (Say), Cx. stigmatosoma (Dyar), Cx. salinarius (Coquillett), Cx. tarsalis (Coquillett) and Cs. particeps (Adams). In non-MZMV areas, 11 species were recorded; Ae. aegypti was most abundant and distributed and Ae. albopictus was at two municipalities. Reported organisms included mosquito vectors of arbovirus, suggesting potential transmission and outbreaks in the MZMV and other areas of the State of Mexico.
