An appraisal of post flood dengue vector Aedes albopictus Skuse (Diptera: Culicidee) surveillance in a coastal district of Kerala, India

Alappuzha coastal district was worst affected by floods due to the heavy rainfall in August 2018. Aedes albopictus survey carried out in the post flood/ disaster areas covering 1,140 households revealed maximum larval positivity in plastic/leather followed by metal and earthen containers. The House index ranged from 1.75 to 12.28 per cent whereas the container index ranged from 1.73 to 20.51 per cent. Breteau index ranged from 3.5 to14.3. As dengue is endemic in the district, there exists a potential outbreak of the vector borne disease.
