There isn't a requirement, per se. I'd certainly do it anyway. A couple runs of bridging on an average span will help make the floor less bouncy.

I personally would use bridging on spans over 8'. Don't know if or what code may be. As KC said, gives a much more solid job.

I was under the impression that any joist with an open span over 8' needed blocking or bridging. Stud walls over certain heights also require it. I always thought it was a code requirement. Termite?

Sort of true. IRC 507.1 requires bridging for joists exceeding nominal 2x12 every 8'. 2x12 and down do not require bridging by code.

Stud wall rack bracing is a whole different animal for a different thread.
