Illustrated key to West-Palearctic genera of Pteromalidae, Hymenoptera, Chalcidoidea

Pteromalids develop as parasites of various stages of other insects or spiders. They are represented in the West-Palearctic region (Europe, North Africa and part of the Middle East) by 16 subfamilies, 221 genera with 10 subgenera, and probably more than 1 000 species. Therefore, they play a major role in agriculture, forestry and nature in general. However, knowledge of the group is rather poor and even identifications at the generic level are difficult.
This book will provide teachers, students, workers in applied entomology, crop protection, plant quarantine, with a useful tool for assessment of the ecological value of Pteromalidae and of their potential for pest control.
