  We study the baryonic fluctuations from second to eighth order involving
electric charge, baryon number and strangeness below the quark-gluon plasma
crossover and numerically known from lattice QCD calculations. By considering a
particular realization of the Hadron Resonance Gas model, we provide evidence
on the dominant role of quark-diquark degrees of freedom to describe excited
baryonic resonances. After proving by means of suitable Polyakov loop
correlators that the quark-diquark and the quark-antiquark forces coincide,
$V_{\bar q q } (r) = V_{\bar q D } (r) + \textrm{const}$, we find that the
corresponding susceptibilities can be saturated with excited baryonic states in
a quark-diquark model picture.
