The following types in natural population of a food infesting acarid mite, Carpoglyhus lactis L., which lives in the miso brewing tank are found by the occurrence probability method^<2,3>) Ad type……Adults dominant. A・N type……Adults and nymphs dominant. N type……Nymphs dominant. L type……Larvae dominant. L・E type…Larvae and eggs dominant. E type……Eggs dominant. X type……Adults, nymphs and larvae are almost equal in number, but the egg is few in number. Y type……Every fourth stage is almost equal in number. From the number of eggs contained in an adult female of the mite, the populations may be classified into 5 types(Fig.1). By combining these two groups of population types, it becomes clear that there are two courses from a population which is mainly formed by the younger stage to that formed by the older one. One leads to the Ad-B population, the other to the Ad-A population(Fig.2), the former is the progressive course, and the latter is the decaying one.
