List of species of Pentatomids (Hemiptera: Pentatomidae) in the hazelnut orchards of Sakartvelo (Georgia) and their potential parasitoids

Abstract

During this survey in the hazelnut orchards of Sakartvelo (Georgia) 12 species of pentatomids were recorded. The following species are recorded from Georgia: Graphosoma lineatum (Linnaeus,1758), Halyomorpha halys (Stal,1855), Pentatoma rufipes (Linnaeus,1758), Rhaphigaster nebulosi (Poda,1761) and Nezara viridula (Linnaeus,1758). From the 72 recorded species in Georgia 21 of them have parasitoids from the superfamilies Platygastroidea and Chalcidoidea and this number reaches 32 species from Palaearctic region. However only 14 species of them had been recorded from Caucasus and 9 from Georgia, where hosts are known. Additionally, Trissolcus manteroi (Kieffer, 1909) and Tr. oobius (Kozlov, 1972) from the Caucasus are reported, but their hosts are unknown.
