Results from our recent investigations of quark number susceptibilities in both quenched and 2‐flavour QCD are presented as a function of valence quark mass and temperature. A strong reduction (∼40%) is seen in the strange quark susceptibility above T c in both the cases. A comparison of our isospin susceptibility results with the corresponding weak coupling expansion reveals once again the non‐perturbative nature of the plasma up to 3 T c . Evidence relating the susceptibility to another non‐perturbative phenomena, pionic screening lengths, is presented.
