Distribución de Aedes albopictus (Skuse) en Nuevo León, México, 2001-2004

Objective. To determine the distribution of Aedes albopictus (Skuse) in Nuevo Leon between 2001 and 2004. Material and Methods. Standardized methods were used to collect 6371 samples of mosquito's larvae from 167 sites. The proportions of samples positive for Ae. albopictus were obtained by municipality and year, using the software program Excel. Results. There were 1 179 samples positive for Ae. albopictus. This species was distributed over 10 municpalities, as follows:Five on the Gulf of Mexico Coastal Plains, which predominantly have a semi-warm, sub-humid climate, and precipitations almost year round (Allende, Montemorelos, Linares, General Teran, and Santiago); two (Sabinas Hidalgo, and Cadereyta) localized on the North American Great Plains,which have a warm,semiarid climate,and scarce precipitations. The final three were Apodaca, San Nicolas, and Escobedo distributed over the metropolitan area of Monterrey City. Conclusions. Up to January 2004, the second most important epidemiological vector in the transmission cycle of Ae. albopictus worldwide was found in ten municipalities of Nuevo Leon State, Mexico.
