Abstract

A total of 7331 mosquitoes were collected in South (Maros and North Toraja) and West Sulawesi (Pasangkayu), using Animal Barrier Screen (ABS) and Kelambu Trap (KT) to characterize the vector community. Mean per night in ABS=128.62 and KT=124.17. Aedes and Culex tended to be trapped in KT (2 locations) than ABS (1 location), whereas Anopheles was the opposite. Armigeres, Lutzia, Mansonia, and Mimomyia are very few and balanced in ABS and KT. Anopheles and Culex are abundant at all three sites, while Aedes and Armigeres are abundant in Maros. Mansonia and Lutzia are mostly in North Toraja, while Mimomyia is only in Pasangkayu. Culex and Anopheles show nearly the same catch pattern in Maros and North Toraja, abundant at 18.00 then decreased and rose again at 20.00 then decreased. Aedes, Armigeres, Lutzia, Mansonia, and Mimomyia tend to decline every hour. Mosquitoes in Pasangkayu tend to be evenly distributed every hour, although there was a slight increase at 23.00. Arbovirus detection in 202 mosquito pools obtained by one pool was positive for Bunyamwera virus (Culex tritaenhyorinchus) in Maros. This latest information will be used as a reference in related research and as a form of arbovirus alertness, so that research on arbovirus detection is still being carried out
