We discuss results on the Polyakov loop susceptibilities in SU(3)

lattice gauge theory. The longitudinal and transverse fluctuations of the

Polyakov loop, as well as, that of its absolute value will be introduced

in the context of the confinement-deconfinement phase transition.

We will indicate the influences of fermions

on the Polyakov loop fluctuations, based on lattice calculations in 2- and

(2+1)-flavors QCD. We show, that ratios of different susceptibilities of

the Polyakov loop are excellent probes of critical behavior. We will

formulate an effective model for the

Polyakov loop coupled to fermions and discus its applications to QCD

thermodynamics. We emphasize the role of fluctuations to fully explore

properties of QCD in the limit of heavy flavours.
