This study confirmed that the most parasitoids that attack cynipid
rose gall wasp are members of the superfamily Chalcidoidea.
Rose gall is caused by a wasp species that lays its eggs in plant tissue and also injects a chemical that creates large brown or grey, rounded swellings on the stems.
The analysis indicates that the oak gall wasps in the tribe Cynipini, here represented by Andricus, Neuroterus, and Biorhiza, form a monophyletic group and that they are closely related to Diplolepis, the
rose gall wasps.
Our purpose is to record information obtained on the
rose galls, ground beetles, and ground-dwelling spiders at Fort Severn and draw attention to the potential of the a rea for biological studies near the tree line in Ontario.
