HEDQVIST, K.-J. Bark beetles enemies in Sweden. II. Braconidae (Hymenoptera). 1998. 87 pp. SEK 150.

The paper is a result of an inventory work on braconid enemies to Swedish bark beetle species. It was carried out in 1979 to 1989 and my own collections for this purpose covers most of the Swedish landscapes (see map). As a comparison to Swedish conditions an account is given to European investigations and conditions in this field. Also, information on braconids and their parasitoids is extracted from the literature and a table of valid names and synonyms is presented. Braconid morphology is briefly treated to enlighten terms used in the keys and descriptions.


A chapter is devoted to braconid biology, behaviour, mating and methods for finding hosts for oviposition. Species known to occur in Sweden are listed together with their hosts. Methods for collecting, rearing and preparation are shortly described and illustrated. Under the heading ”Taxonomy” all braconid enemies to bark beetles known to occur in Sweden are treated: synonymies, morphological characteristics, hosts and known distribution are given. Keys to all subfamilies, genera and species are provided. The information is summarized in a table showing all Swedish bark beetle species with their braconid parasitoids.


A chapter is devoted to the braconid enemies. Also, the importance of Braconidae to forestry is discussed showing their role in controlling bark beetles. A summary in Swedish is given.
