  We study the spontaneous pair production of scalar dyons in the near extremal
dyonic Kerr-Newman (KN) black hole, which contains a warped AdS$_3$ structure
in the near horizon region. The leading term contribution of the pair
production rate and the absorption cross section ratio are also calculated
using the Hamilton-Jacobi approach and the thermal interpretation is given. In
addition, the holographic dual conformal field theories (CFTs) descriptions of
the pair production rate and absorption cross section ratios are analyzed both
in the $J$-, $Q$- and $P$-pictures respectively based on the threefold dyonic
KN/CFTs dualities.
