Bischoff, A. Fischer, B. Liebenberg] The determination of mite numbers in dust samples depends on the effectiveness of the sampling procedure. We report on mite isolation from dust samples by flotation distinguishing between living and dead mites. The results are varied and unreproducible; ageing processes are of relevance in the case of dead mites. Living mites can be determined more reliably when using mite mobility. Two methods based on this principle, the mobility test and the heat escape method, are described and discussed. In the case of a natural analogous mite development on carpets, mite numbers ranging from 80 000 to 200 000 mites per m2 are found after approx. 3 months. It is shown that the mobility of different mite species varies. The mobility test allows the detection of mites in textile objects, and shows how mites are distributed over these objects. It is demonstrated how the infestation of clothes by mites can be determined. Elsevier Science Publishers B.V., 1992 Bischoff E. Indoor Medical Biology Research Center, Mainz, Germany aut Fischer A.
