Considering the influences of collective dephasing,multilocal qutrit-flip,local qutrit-flip,and the combination of global mixed noise,we study the dynamics of entanglement and the phenomenon of distillability of sudden death (DSD) in a qutrit-qutrit system under various decoherent noises.It is shown that the system always undergoes DSD when it interacts with multilocal and local qutrit-flip noise,and the time-determined bound entangled state is more dependent on different noises.Comparing with the cases of global mixed and collective dephasing noise,we conclude that the qutrit-flip noise is responsible for the DSD.
