Tyrophagus lintneri (Osborne)
Common name.—Mushroom mite.
Associate.—Pycnoscelus surinamensis, U.S.A. (Roth and Willis, unpublished data, 1953): Mite determined by Dr. E. W. Baker (personal communication, 1953). Although this mite was found on the cockroach, it is a known pest in stored foods (Baker and Wharton, 1952) and probably was brought into the culture with food. Rau (1924) reported that the food of Blatta orientalis often became infested with this species, but it did not affect the health or mortality of the cockroaches in his culture.
