Mosquito fauna of "Toh Daeng" swamp forest, Thailand.

Entomological surveys (2001-2005) were carried out in Narathiwat Province to determine mosquito fauna of the peat swamp forest. Fifty-four species belonging to 13 genera were identified from 837 larval specimens and 3,982 adult mosquitoes. These included the major vectors for Brugian fillariasis: Mansonia annulata, Ma. bonneae, Ma. dives, Ma. uniformis and Ma. indiana. Ma. annulata and An. letifer were reported for the first time in Thailand as lymphatic filariasis vectors. Three species inhabiting Nepenthes pitchers (N. mirabilis): Tripteroides tenax, Toxorhynchites manopi and Uranotaenia edwardsi, were recorded for the first time in Thailand; Zeugnomyia gracilis was also found common in the peat swamp forest.
