The species listed by JAHN (1948JAHN ( , 1958 are included in the tables mentioned because they originate from localities situated between 2 study areas and are part of the Central European Alps.…”

There are 109 species of primary and secondary parasitoids associated with Zeiraphera diniana GO,NEE in the Central European Alps. Ninety species are primary, 6 facultative secondary and 13 obligate secondary parasitoids. At family level, the composition of the complex seems to be the same in every outbreak area of the host, with ichneumonids predominating. In the Upper Engadine Valley (Switzerland), where intensive studies were conducted over a period of 3 consecutive outbreak periods (28 years moths into the outbreak areas during the phase of host density increase is very important. The rate of increase of the natural enemies --which are univoltine --can never equal or exceed that of their host ; consequently, control by these natural enemies alone is not possible.
