VILLEGAS-TREJO, Alejandro et al. Targeted treatment of Aedes aegypti at localities with high risk for dengue transmission, Morelos, Mexico. Salud pública Méx [online]. 2011, vol.53, n.2, pp.141-151. ISSN 0036-3634.

OBJECTIVE: To determine the relative importance of Aedes aegyti breeding sites for potential targeted dengue control interventions in Morelos. MATERIAL AND METHODS: Cross-sectional entomological surveys were conducted and collection of Ae. aegypti pupae was taken from all water-holding containers in Cuautla, Jojutla and Tlaquiltenango during dry (1 713 households) and rainy (1 677) seasons in 2008. Relative importance of different types of breeding sites was determined by the contribution (%) to total pupae production within each locality. RESULTS: In Cuautla most pupae during the dry season were found in wash basins (48.5%), tanks and buckets/pots (15% each); during the rainy season, diverse small items (21.3%), buckets/pots (19.3%) and plant pots (12.9%) were more productive. In Jojutla and Tlaquiltenango, 97% of all pupae was found in plant pots during the dry season; during the rainy season diverse small items (26.3%), washing/cooking utensils (13.9%), buckets/pots (12.9%) and plant pots (12.7%) were significant. CONCLUSION: Prevention and control of the dengue vector should be based on this kind of evidence to target the most productive breeding-sites.
