ABSTRACT
The relationships between ration components for livestock and dipterous fly larvae and predaceous mites inhabiting dung of farm animals were studied and discussed. A positive result was detected between wet rations and dipterous fly larvae; an opposite result was observed relative to predaceous soil mites. Dipterous fly larvae in manure are available as food for predaceous soil mites. Certain species of the families Macrochelidae, Rhodacaridae, Parasitidae, Uropodidae and Cheyletidae are predaceous on fly larvae and play a role as biocontrol agents.
