Two stored-product mites were exposed, at 21±1 °C and 75±2% relative humidity, to 10 species of Penicillium cultured on potato-dextrose-agar slants. P. cyclopium Westling was the most favorable and P. implicatum Biourge the least favorable diet for feeding and reproduction of both mites. Generally, both species of mites bred successfully on those fungal cultures on which they fed well. The mushroom mite, Tyrophagus putrescentiae (Schrank) was the more efficient fungivore; the numbers of times the grain mite, Acarus siro L., and T. putrescentiae increased in 1 month on each species on Penicillium were: P. canescens Sopp – 13, 117; P. chrysogenum Thom – 7, 219; P. herquei Bainier & Sartory – 15, 244; P. frequentans Westling – 4, 115; P. lilacinum Thom – 0, 55; P. cyclopium – 33, 517; P. spinulosum Thom – 5, 151; P. thomii Maire – 11, 156; P. implicatum – 0, 0.
