Bionomics study of Mansonia (Diptera: Culicidae) in a filariasis-endemic area of Sedang Village, Banyuasin Regency, South Sumatra, Indonesia

Abstract

An investigation of bionomic study of Mansonia species was successfully conducted in Sedang village which is one of the filariasis-endemic areas in Indonesia. The study was carried out for 14 months from April 2017 to May 2018. In order to trap the local mosquitoes in the study area, indoor and outdoor human landing collection method was adopted. During the study, 7,908 mosquitoes were collected which consisted of 13 genera and 40 species of mosquitoes. Moreover, Mansonia uniformis, M. annulifera, and M. indiana were found to be the most abundant, dominant, and high frequency mosquitoes. The filariasis vector analysis through polymerase chain reaction test confirmed that only Mansonia annulifera positively detected as the filariasis vector. Furthermore, the longevity calculation showed that 81% of all the collected Mansonia spp. had already oviposited their eggs which indicates that the studied area possesses high possibilities of filariasis transmission.

A Review of Bed Nets Usage and Sewerage Conditions as Risk Factors for Lymphatic Filariasis in Developing Countries

“…Research conducted in Banyuasin, South Sumatra, Indonesia, by analyzing lymphatic filariasis vectors through PCR tests confirmed that only Mansonia annulifera was detected as positive as a lymphatic filariasis vector. In that study, Brugia malayi was detected as captured Mansonia annulifera (39). This corresponds to the data provided by the Indonesian Ministry of Health, indicating that Brugia malayi is responsible for 70% of lymphatic filariasis cases in Indonesia (40).…”
