Hymenopteran parasitoids of European gall midges

The dataset comprises occurence and host records of hymenopteran parasitoids associated with gall midges (Cecidomyiidae, subfam. Cecisomiinae) in Europe. It comprises data obtained by a range rearing techniques, incl. rearing adult wasps from parasitoid larvae extracted from galls, directly from parasitized gall midge larvae within galls or from gall midge larvae transferred to soil to pupate there, in many cases after hibernation. Documentation of rearing techniques and results are found in Bruun et al. (2024).
