What is the reason for not using transposition table in quiesce search? most programs don't use it, but I have seen very few that use it.

Probing the transposition table in the quiesce search will hurt nps, but should lower total node count. So it's a trade-off. For engines that don't do it, the effective gain was likely found to be negative.

Another reason could be that storing results in the transposition table during the quiesce search will more quickly fill the table thereby preventing more valuable information from being stored. However, that can be remedied by a proper replacement strategy.
