The effect of the Hawking temperature on the entanglement and teleportation for the scalar field in a most general, static, and asymptotically flat black hole with spherical symmetry has been investigated. It has been shown that the same ``initial entanglement'' for the state parameter \ensuremathα and its ``normalized partners'' √1\ensuremath-\ensuremathα2 will be degraded by the Hawking effect with increasing Hawking temperature along two different trajectories except for the maximally entangled state. In the infinite Hawking temperature limit, corresponding to the case of the black hole evaporating completely, the state no longer has distillable entanglement for any \ensuremathα. It is interesting to note that the mutual information in this limit is equal to just half of the ``initially mutual information.'' It has also been demonstrated that the fidelity of teleportation decreases as the Hawking temperature increases, which indicates the degradation of entanglement.
