Entomological Sampling Strategy, Sampling Tools and Analytical Techniques with regard to Vector-Borne Diseases: Indian Perspective

Entomological surveillance is an integral component of surveillance activities for any vector-borne disease. The vector surveillance in a given area shall depend on the laid down objective and keeping in view of the expected outcome. The sampling strategy for vector surveillance shall depend on routine entomological surveillance, outbreak situation and insecticide resistance monitoring. The selection of any sampling strategy and technique should always be kept in mind for its appropriate application depending on the target species. The sampling strategy shall imply that vector surveillance teams are supposed to select different options depending on the short or long term study at hand. The present ongoing operational vector sampling methods usually lack standardisation, quantitative comparisons across different situations in case of outbreak situations and one time measurements, and it makes it difficult to assess the real situation. The sampling strategy should always meet the requirement of the laid objectives to fulfil the desired outcome. The present document is an attempt to act as a guiding principle for use as appropriate sampling strategy for any vector-borne diseases in the country.
