A series of experiments were conducted on nine gamasine mites, offering ten prey items in the laboratory. Hypoaspis aculeifer was the only mite with consumption recorded for each food. The remaining predators had intermediate prey spectra except Alliphis hallel·i which fed on nematodes only. These feeding categories of gamasine mites might have an influence on the prey occurring in the same habitat. The acceptability of the prey related to the morphological features of the predators has been discussed.
