Abstract:
Objective To understand the species and the distribution of parasitoids in the galls of the cynipid wasps on Quercus variabilis in China, an investigation was conducted from 2019 to 2022. The results will lay a foundation for biological control of cynipid wasps. Method The cynipid wasp galls on Q. variabilis were collected through field investigation. The parasitoids in the galls were reared under laboratory conditions, and the specimens were both examined and identified. Result A total of 26 species of parasitoids belonging to 9 families, 17 genera, with 5 new records in China, were identified in the galls from 12 species of cynipid wasps on Q. variabilis in China. Their distribution was introduced. Conclusion This study reports 26 parasitoids species in the galls of cynipid wasps on Q. variabilis, and summarizes their corresponding gall morphology and distribution. In addition, color photographs of galls and parasitoids are acquired.
