The possibility of nutrition of three species of mites with substrates containing coIlagen, ossein, keratin is studied. It was established that in gut of the mite species under study the given proteinoids are not digested and there are no conditions for this process. It is proved that nutrition of the above-mentioned species of mites on such substrates as ligamentes, tendons, skin, feathers, horn, etc. occurs not due to digestion of proteinoids but due to digestion of accompanying lipid substances.
