We study how environment regulates the star formation cycle of 33 Virgo Cluster satellite galaxies on 720 pc scales. We present the resolved star-forming main sequence for cluster galaxies, dividing the sample based on their global H I properties and comparing to a control sample of field galaxies. H I-poor cluster galaxies have reduced star formation rate (SFR) surface densities with respect to both H I-normal cluster and field galaxies (~0.5 dex), suggesting that mechanisms regulating the global H I content are responsible for quenching local star formation.
