Effects of Temperature and Humidity on Cheese Mites: With Review of Literature (Classic Reprint) - Softcover
Synopsis
Excerpt from Effects of Temperature and Humidity on Cheese Mites: With Review of Literature
Life history studies with Acarus siro L. And Tyrophagus putrescentiae (sohr.) on cheese showed that no eggs of either species of cheese mites hatched at 32° F. Regard less of the relative humidity (r. H. At 38° F. Eggs that were incubated at a r. H. Of 84, 92, or 100 percent hatched and developed to maturity. The average development time at 38° F. And 100 percent r. H. Was 137 days for A. Siro and 169 days for putrescentiae. Some eggs hatched at r. H. Of 68 and 76 percent, but the larvae failed to develop to maturity.
Tests at and 56° F. Showed that, as the temperature was raised, the length of time required for a mite to complete its life cycle was reduced. At 56° F. And 100 percent r. H. A. Siro required only 26 days and T. Putrescentiae 38 days. As the relative humidity at each temperature was decreased, the length of the life cycle of the mites was increased. Although a few eggs sometimes hatched at a r. H. As low as 48 percent, the resulting larvae seldom reached adulthood at a r. H. Of less than 61 percent.
The rate of development of different individuals under the same conditions varied considerably. Mold growth also seemed to influence the rate of development to some extent. Typical approximate percentages of time spent in each stage of development were: Egg, percent; larva, 16; resting larva, 7; protonymph, 12; resting proto nymph, 7; deutonymph, 14; and resting deutonymph, 8 percent. A hypopus stage in the Species studied was never encountered in any of the low-temperature tests and probably is very rare.
