Present and future expected limits on interactions between dark matter and various quarks are thoroughly investigated in a model-independent way. In particular, the constraints on the interactions from the Large Hadron Collider (LHC) experiment are carefully considered with a focus on mono jet + missing transverse energy ((E) over bar (T)), mono b-jet + (E) over bar (T), and top quark(s) + (E) over bar (T) channels. Model-independent upper limits (expected limits) on the cross section times acceptance for non-standard model events are derived for the LUC operating at 7/8/14TeVs. Assuming that the dark matter is a singlet real scalar or a singlet Majorana fermion, we also put constraints on several operators describing its interactions with up, down, strange, charm, bottom and top quarks. These constraints are compared to those obtained from cosmological and astrophysical implications.
