ABSTRACT

Dengue fever represent an importante public health problem in Mexico. Mosquito behavior has changed because is moving from houses to non-residential places such as vacant lots, markets, parks, and factory backyards; and therefore, it poses a challenge to typical mosquito control carried out only in houses. This study was aimed to 1) to evaluate the presence of Aedes agypti breeding sites in non-residential places, 2) to determine mosquito survival to Winter conditions, and 3) to integrate Google Earth software as a new tool to better understand the disease epidemiology. Field surveys to assess type and frequency of larval breeding sites were conducted from December, 2007 to March, 2008. Study sites were assorted industrial buildings in Monterrey, San Nicolas, Apodaca, Guadalupe and Escobedo (Nuevo León, México) and always located all of them near of residential areas. Ten percent of buildings reported dengue in the indoors whereas 70% recorded dengue in the outdoors. Owners of these industries reported that only 18% applied larval control with Temephos, 8% did mosquito professional control, and 74% never treated these areas. On the other hand, 97% of buildings reported presences Aedes aegypti breeding sites: 90% dry, 7%, and 3% had been treated with Temephos 1% granules. Conversely, it also supported the fact that Ae. aegypti does not discriminate backyards breeding sites. The study described adaptation or survival of the mosquito vector during Winter or cold ambient temperatures. Mosquito and breeding sites were also prevalent during all sampled municipalities. It is concluded that entomological risk poses a challenge for future dengue outbreaks in the metropolitan area of Monterrey.
