  Motivated by recent inferred form of the halo occupation distribution (HOD)
of X-ray selected AGNs, in the COSMOS field by Allevato et al. (2012), we
investigate the HOD properties of moderate X-ray luminosity Active Galactic
Nuclei (mXAGNs) using a simple model based on merging activity between dark
matter halos (DMHs) in a $\Lambda$-CDM cosmology. The HODs and number densities
of the simulated mXAGNs at $z=0.5$, under the above scenarios to compare with
Allevato et al. (2012) results. We find that the simulated HODs of major and
minor mergers, and the observed for mXAGNs are consistent among them. Our main
result is that minor mergers, contrary to what one might expect, can play an
important role in activity mAGNs.
