S. Arumugam and J. Suresh Suseela introduced the concept of acyclic graphoidal covering of graphs[5]. S. Arumugam and C. Pakkiam [3] have determined the graphoidal covering number of several families of graphs. A complete survey of the various results in graphoidal covers and graphoidal graphs is given in [4]. In this paper, we study the properties of acyclic graphoidal coverings of zero divisor graph and we also obtain a characterization of acyclic graphoidal coverings of complete and complete bipartite zero divisor graphs.
