We explore in the redshift range 110^10M_Sun) and that the fraction of galaxies hosting such powerful quasars monotonically increases with the stellar mass. The fraction of Type-2 QSO hosted in star-forming galaxies increases with redshift: 50% at z 1 and 70% at z 2. The specific star-formation rate of these hosts is comparable to what measured for normal star-forming galaxies. The morphological analysis of the ACS images has indicated that the majority of the host galaxies are bulge dominated, there being a few cases of disk galaxies or mergers. We will discuss the implication of these findings on the importance of major mergers as triggers for the accretion activity in obscured quasars.
