We　study　detection　of　genuine　multipartite　entanglement　based　on　one-particle　loss　operator.　We　obtain　a　criterion　on　detecting　genuine　pure　tripartite　entanglement.　The　results　are　then　generalized　to　arbitrary　pure　multipartite　states.　For　mixed　states　by　using　the　correlation　tensors　of　the　Bloch　representation　of　density　matrices,　we　obtain　an　effective　criterion　of　arbitrary　dimensional　genuine　tripartite　entanglement.　Detailed　examples　are　given　to　show　that　our　criterion　is　able　to　detect　more　genuine　tripartite　entanglement　states　than　some　existing　criteria.
