The HRS is a complete volume-limited sample of nearby objects including Virgocluster and isolated objects. Using a recent compilation of HI and CO data westudy the effects of the cluster on the molecular gas content of spiralgalaxies. We first identify M* as the scaling variable that traces the total H2mass of galaxies better. We show that, on average, HI-deficient galaxies aresignificantly offset from the M(H2) vs. M* relation for HI-normal galaxies. Weuse the M(H2) vs. M* scaling relation to define the H2-deficiency parameter.This parameter shows a weak and scattered relation with the HI-def, here takenas a proxy for galaxy interactions with the cluster environment. We also showthat, as for the HI, the extent of the H2 disc decreases with increasingHI-deficiency. These results show that cluster galaxies have, on average, alower H2 content than similar objects in the field. The slope of the H2-def vs.HI-def relation is less than 1, while the D(HI)/D(i) vs. HI-def relation issteeper than the D(CO)/D(i) vs. HI-def relation, thereby indicating that the H2gas is removed less efficiently than the HI. This result can be understood ifthe HI is distributed on a flat disc more extended than the stellar disc, thusless anchored to the gravitational potential well of the galaxy than the H2.There is a clear trend between the NUV-i colour and H2-def, which suggests thatH2 removal quenches the activity of star formation. This causes galaxiesmigrate from the blue cloud to the green valley and, eventually, to the redsequence. The total gas-consumption timescale of gas deficient cluster galaxiesis comparable to that of isolated systems, and is significantly larger than thetypical timescale for total gas removal in a ram pressure stripping process,thus suggesting that ram pressure, rather than starvation, is the dominantprocess driving the evolution of these cluster galaxies.
