Entomological study of flariasis vector in transmission presented area of SuratThani, 2014.

Abstract

The aim of this study was to investigate the species together with density of lymphatic filarial mosquito vector in lymphatic filariasis transmission of Surat Thani Province. The rates of infection and transmission of microfilaria in mosquito vector were conducted by using volunteers as baits with in two study sites;1) BangKamyan village Moo 2 Sincharoen subdistrict, Phrasaeng district and 2) Namkeang village Moo 2, Ban Na subdistrict, BanNaderm district. The each of captured mosquitoeswas dissected to detect the micro filarial worm. It was found that lymphatic filarial mosquito vector in both areas were existed. Two main vectors found in BangKamyan village Moo 2. Sincharoen subdistrict, Phrasaeng district were Ma. uniformis and Ma. Indiana which were relative high density. Where asthree dominant vectors found in Namkeang village Moo 2, Ban Na subdistrict, Ban Naderm district were Ma. annulata, Ma. bonneae and Ma. indiana. The high density of the lymphatic filarial mosquito vectorin both areaswas found mainly between 19.00-20.00 pm and then gradually decreased. The micro filarial in mosquitoes were not found in both areas. So, Entomological surveillance is necessary to take action in this area in order to observe whether the mosquito is infected by micro filarial worm.
