. Bandung district has been implemented mass drug administration (MDA) program since 2009, but little is known about entomological data especially about bionomic aspects and distribution of lymphatic filariasis (LF) mosquito vectors. This study was aimed to identify potential LF mosquito species and its potential breeding sites in two LF endemic villages in Majalaya, Bandung district. The observational study was conducted in September-October 2013. Mosquito larvae were collected by a scoop and adult mosquitos were captured through indoor-outdoor human-landing and resting collection to identify species diversity and density. Six species filariasis mosquito vectors were identified. The primary LF vectors, Culex quinquefasciatus and Cx. tritaeniorhynchus were found as dominant species with peak landing time between 9 p.m. – 1 a.m. Five potential breeding sites was identified near to villages including neglected fish-pool and paddy field with salinity 0‰, water temperature 28.5-29°C, pH 6-7. The Man-Hour Density (MHD) and Man-Biting Rate (MBR) of Cx. quinquefasciatus was relatively low, however, transmission may potentially occur due to their existence and the availability of favorable environmental conditions across the villages.
