We report a method for rearing Diplolepis mayri (Schlechtendal) and D. rosae (Linnaeus) under controlled conditions using Rosa rubiginosa (L.) and R. canina L. wild rose shrubs. Plants were kept at a temperature of 22–23°C, 60%–70% humidity, with L14:D10 (2023) and L16:D8 (2024) photoperiod cycles. A second D.

ABSTRACT In this work, we investigate the native parasitoid community colonising galls by an invasive pest: the oriental chestnut gall wasp (OCGW), Dryocosmus kuriphilus (Hymenoptera; Cynipidae). We tried to understand how native parasitoids react after the arrival of the pest (two‐year sampling period) in the province of Zamora (Castilla & León region,
