The Hymenopterous Parasitoids of the Lime Leaf Miner Phyllonorycter issikii (Kumata) (Lepidoptera: Gracillariidae) from Its Native and Invaded Regions in Asian Russia

Abstract

The lime leaf miner Phyllonorycter issikii (Kumata) (Lepidoptera: Gracillariidae) is an east Asian pest, which has recently distributed across the Palaearctic. Here, we provide the novel data on the diversity of its parasitoids in the Russian Far East (native region) and western Siberia (invaded region). Overall, 19 parasitoids from the Eulophidae (17 species) and Braconidae (2 species) reared from the Ph. issikii larvae and pupae were identified based on morphology and/or DNA barcoding. Among them, 12 species were detected in the Primorskiy Territory (Russian Far East) and 10 species in the Novosibirsk Province (Western Siberia), with only 3 shared species, namely Chrysocharis laomedon (Walker), Elachertus inunctus Nees and Sympiesis gordius (Walker). Pleurotroppopsis japonica (Kamijo) is a novel record for Russia, whereas the other eight eulophids are novel for the Novosibisk Province and two for the Primorskiy Territory. The eulophid Mischotetrastichus nadezhdae (Kostjukov) was recorded as a parasitoid of Ph. issikii for the first time. Four new species were described from the Primorskiy Territory: Achrysocharoides nagasawi sp. nov., A. carinatus sp. nov., Cirrospilus ussuriensis sp. nov., Pholetesor nataliae sp. nov. For all parasitoids, the distribution and hosts are listed; the majority of the species are illustrated. In addition, a checklist of the Ph. issikii parasitoids counting 79 species is compiled for the Palaearctic region.
