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.

Diversity and Abundance of Mosquitoes in the Seaport Area of San Pedro (Côte d’Ivoire)

“…The species richness of the Culex genera can be explained by their ability to adapt to several types of breeding sites. These results differ from those of Konan et al 10 and Yao et al 11 at the port of Abidjan in Côte d'Ivoire and those of Bhadauriya et al 6 at the port of Kandla in India. In these works, carried out in different ports, mosquitoes were collected with very few species of the genera Culex.…”

“…28 According to Cornet et al, 27 urbanisation leads to a variation in the composition of species of genera Aedes mosquitoes causing a dominance of Aedes aegypti. It was found by Bhadauriya et al 6 that the proliferation of Aedes aegypti was related to the mismanagement of fire extinguisher buckets. The results agree with those of Konan et al 10 and Yao et al 11 at the port of Abidjan, Côte d'Ivoire where Aedes aegypti accounted for over 83% of the mosquito species collected.…”

“…[3][4][5] The spread of these arboviruses and their vectors has been facilitated by globalisation and increased trade in goods and people. 6 Thus, today, no region is immune to the risks of importation. 7 In response to this ongoing threat, the International Health Regulations recommend establishing vector surveillance systems at points of entry and developing evidence-based vector control strategies to prevent the spread of the diseases they transmit.…”
