First records of three parasitoid Hymenoptera for the Hellenic fauna: Proctotrupes gravidator (Proctotrupidae), Dirhinus hesperidum (Chalcididae) and Oodera formosa (Ooderidae)

Key Points

This study aims to provide the first records of three parasitoid species in Greece and discuss their ecological implications.
Documented the occurrence of Proctotrupes gravidator, Dirhinus hesperidum, and Oodera formosa in Greece.
Analyzed potential host-parasitoid associations, especially involving grapevines and Agrilus derasofasciatus.
Recorded the first instances of the identified parasitoids in Greece.
Noted a potential association between O. formosa and the pest Agrilus derasofasciatus.
Discussed the implications of these findings for the ecological networks in Greece.

Abstract

This study reports the first records of Proctotrupes gravidator (Proctotrupidae), Dirhinus hesperidum (Chalcididae) and Oodera formosa (Ooderidae) in Greece. The co-occurrence of O. formosa and Agrilus derasofasciatus (Buprestidae) suggests a potential host-parasitoid association, as well as a possible new plant association with grapevines. The currently observed geographic distribution of these species in Greece is discussed.
