Diplolepis eglanteriae is a cynipid wasp inducing characteristic
smooth pea-like galls on Rosa sempervirens. The gall was first reported as occurring
in Malta in 1926 at Buskett. During the present study, the presence of this gall was
confirmed and although it was not found again in Buskett it was found in three other
localities on Malta. Three chalcid parasitoids were found associated with these galls,
namely Eupelmus (Macroneura) muellneri Ruschka, 1921 (Eupelmidae), Stepanovia
eurytomae (Nees, 1834) (Eulophidae) and Pteromalus sp. near bedeguaris
(Pteromalidae); the latter two are here recorded for the first time from the Maltese
Islands.peer-reviewe
