Due to the problem presented by parasites, when develop resistance to antihelmintic medical, important alternative procedures of parasites control has been researched, among then, the biological control by nematophagous fungi has great importance. In order to use biological control in field application, the challenger is to produce the nematophagous fungi massively and to storage it to long term without losing mass production and predatory capacity. The aim of this research work was to analyze the lyophilization as a method to preserve this specie of fungi and to incorporate in mineral salt and common salt. A strain of Arthrobotrys musiformis was employed. The results showed that the method allow the fungi to keep its viability, therefore, it could only survive for 1 day when incorporated do the mineral salt and 30 days in common salt.
