The purpose of the research is to identify the potential of the local chitinolitic bacteria as biocontrol of Aedes aegypti L. This research has been conducted in the Microbiology Laboratory of Mathematics and Science Faculty, University of Syiah Kuala. The chitinolitic bacteria were isolated from water that taking in some area in Banda Aceh and Greater Aceh. The method used was an experimental method using completely randomize factorial designed (CRFD) with two factorial and consists of 6 isolates of chitinolitic bacteria and 4 concentrations of bacteria (0.0 mL, 0.5 mL, 1.0 mL dan 1.5 mL). The results show that the isolates bacteria do not have any effect on the Aedes aegypti L. Larvae death in the transformation from larvae to pupa until the seventh observation day. The concentration of the bacteria influences the Aedes aegypti L. larvae death during the transformation larvae to pupa.
