abstract
The aim of this study was to identify the diversity of Simulium in 19 waterfalls of Bogor Forest Management Unit, as well as to know the characteristics of black fly larval stage breeding habitats that affect the abundance of Simulium population. Preparation samples were performed manually from September-December 2017, along with Simulium larvae habitat characteristics measurements simultaneously. The most common Simulium species found in 19 waterfalls of Bogor Forest Management Unit were Simulium (S.) upikae (36.31%), followed by Simulium (S.) argyrocinctum (36.11%), Simulium (S.) eximium (11.12%), and Simulium (S.) celsum (11.04%). Of the 19 waterfalls of Bogor Forest Management Unit observed, the highest number of collections of larvae and pupae found in Panjang Waterfall. Pearson correlation analysis showedsignificant relationship between water temperature, stream width, velocity, the canopy cover with the amount of Simulium found.
