Study on vector mosquito of zoonotic Brugia malayi in Musi Rawas, South Sumatera, Indonesia

Studies to determine abundance, distribution, species composition, and mosquito interactions are very important in understanding the risk of disease transmission to implement appropriate mosquito management in endemic areas. Lymphatic filarial worms are one of the parasites that are contracted and/or transmitted by mosquitoes when sucking the blood of infected humans or animals and then biting others. This research was conducted to study the abundance, species composition, mosquito biting cycles, density and periodicity of mosquitoes caught in Lubuk Pauh Village, Bulang Tengah Suku Ulu, Musi Rawas, South Sumatera, Indonesia, which is an endemic area of zoonotic . The mosquito collection was done in July 2018 using the human landing collection method for 11 h from 18.00 pm to 5.00 am Western Indonesian Time. The catching of mosquitoes was done both indoors and outdoors, and mosquitoes were identified under a dissecting microscope using an identification key to confirm their species. Detection of larvae in mosquitoes was confirmed by dissection and polymerase chain reaction methods. The caught mosquitoes consisted of four species: , , , and . Based on the Shannon-Wiener index, Lubuk Pauh Village has low mosquito species diversity (0.210). s was the dominant mosquito in Lubuk Pauh Village with dominance number 95.08, and it had the most frequent activity in each of periods of indoor and outdoor collection, with the highest density (man-hour density) at 18.00-19.00 (51.750). infective stage larvae were not found in all mosquito species caught. Existence of , , and in Lubuk Pauh Village which is an endemic area of shows that the area is at risk of lymphatic filariasis transmission.
