Entomological Survey for Aedes Species at Deendayal Seaport, Kandla, Gujarat India during Pre-Monsoon Period, 2018

Abstract

Entomological survey was conducted at Kandla international seaport, Kandla, Gujarat, India during pre-monsoon season of 2018 for immature Aedes mosquitoes. Standard entomological techniques were used for survey. All approachable larval breeding habitats were inspected. Inside seaport area, a total of 45 premises were searched for Aedes breeding out of which 02 premises were found inside area of seaport with 4.44 Premises Index (PI), 1.77 Container Index (CI) and 4.44 Breteau Index (BI). Out-side area of seaport (non-residential), none of premises/ containers were found positive for breeding while in out-side residential area 27 were searched out of which 02 houses were found positive for Aedes breeding with 7.4 House Index (HI), 8.10 Container Index (CI) and 11.11 Breteau Index (BI). Intermittent supply of water was the main reason for Aedes breeding in residential colony. From this study it is evident that inside port area and outside port area provided ample habitats for the mosquitoes to breed and thrive in wet season. Regular entomological surveillance is needed not only to monitor the Aedesmosquito breeding in and around port area including residential areas nearby but also to prevent the transportation and establishment of mosquito species in newer areas. Community awareness is also equally important to prevent entry of vector mosquito species in new areas.
