House dust mite
The physical structure and nutritional component of the substrate were found to be decisive factors for the growth and survival of the house-dust mite, Dermatophagoides pteronyssinus. To elucidate the physical limits of the food environment, population growth of D. pteronyssinus was investigated on rearing media as weil as on natural substrate. A more rapid reproduction of D. pteronyssinus on fibrous house-dust, as compared to rearing media consisting of non-fibrous fine particles, indicated that the mite prefers an aerated over a dense substrate. This was shown to be related to the antagonistic effects of the endemie mold, Aspergillus penicilloides, with which the mite establishes a symbiotic relationship. The fibrous component of the mattress microhabitat is a natural biotope for D. pteronyssinus. Deeper mattress fibres may provide a protective niche for mites during winter. They may also provide protection from other adverse environmental conditions.
