ABSTRACT
A mass-production method was developed for the predaceous mite, Macrocheles muscaedomesticae (Scopoli). Using spent house fly media, frozen house fly eggs, and a nematode, Protorhabditis sp., 2500 mites could be produced in eight days from 34.5 female mites at 30°C. Under these conditions, the generation time of this mite was 3.2 days and the mite population could increase as high as 69.8 times per generation. The relationship of the nematode to the rearing of M. muscaedomesticae, and the possible ways to improve the mass-production method are discussed.
