Using the far-infrared emission, as observed by the Herschel Virgo ClusterSurvey (HeViCS), and the integrated HI and CO brightness, we infer the dust andtotal gas mass for a magnitude limited sample of 35 metal rich spiral galaxiesin Virgo. The CO flux correlates tightly and linearly with far-infrared fluxesobserved by Herschel. Molecules in these galaxies are more closely related tocold dust rather than to dust heated by star formation or to optical/NIRbrightness. We show that dust mass establishes a stronger correlation with thetotal gas mass than with the atomic or molecular component alone. Thedust-to-gas ratio increases as the HI deficiency increases, but in highly HIdeficient galaxies it stays constant. Dust is in fact less affected than atomicgas by weak cluster interactions, which remove most of the HI gas from outerand high latitudes regions. Highly disturbed galaxies, in a dense clusterenvironment, can instead loose a considerable fraction of gas and dust from theinner regions of the disk keeping constant the dust-to-gas ratio. There isevidence that the molecular phase is also quenched. This quencing becomesevident by considering the molecular gas mass per unit stellar mass. Itsamplitude, if confirmed by future studies, highlights that molecules aremissing in Virgo HI deficient spirals, but to a somewhat lesser extent thandust.
