Container survey of Aedes breeding sites in a Rural Health Training Centre campus in South West of Delhi

Abstract

Introduction: Aedes mosquito is one of the mosquito species that are most studied because of their potential as vector of dengue and such information can be used to design an effective control measures for campuses. Objective: To study the Aedes breeding sites using the container survey method and to recommend control measures in controlling the Aedes breeding sites. Methodology: The container survey study was carried out in the campus of a Rural health training centre campus which spreads over 30 acres with rich plantation and trees all around. All natural and artificial containers in the vicinity of the campus and reachable tree holes were examined during the survey. The number, type and water condition of containers that may serve as potential breeding sites were examined and recorded. Larvae collection was carried out indoors (interior of the building) and outdoors (outside of the building but confined to its immediate vicinity within the campus limits) by using pre-designed questionnaire. Larva identification was done by motility Pattern. Result: The survey included study of 359 common breeding sites such as cooler, Plastic storage containers, unused plastic waste, cement tanks, syntax tanks, earthen pots, plant pots, solid waste and others in 13 sites and 3 out of the 359 containers contained Aedes larvae. Conclusion: The RHTC management should Practise Integrated Vector Management (IVM) recommended by WHO in the campus. An IVM approach takes into account the available health infrastructure and resources, and integrates all available and effective measures, whether chemical, biological or environmental.
