Feeding preference of the proturan species Nipponentomon nippon (Yosii) was studied under laboratory conditions on three pathogenic fungi, Fusarium oxysporum Schlecht.: Fr., F. solani (Mart.) Sacc. and Cylindrocarpon destructans (Zinssm.) Scholten, and one saprotrophic fungus, Pestalotiopsis sp. N. nippon feeds on all of these fungi indiscriminatingly, although P. sp. is not a preferred food for the fourth instar larva. Some new features of its feeding behavior, including the restriction of "pump" movement in the abdominal segments VIII-XII during the feeding, are described. It is observed that N. nippon feeds on baker's yeast in a mushy state. This observation suggests that its feeding habits also involve "suspension feeding" reported in the collembolan species.
