Parasitoids (Hymenoptera) of the lime leafminer Phyllonorycter issikii (Lepidoptera, Gracillariidae) in different cities of the Russian Federation and their role in the mortality of the invasive pest.
The assemblage of hymenopteran parasitoids associated with the invasive lime leafminer Phyllonorycter issikii (Lepidoptera: Gracillariidae), which develops on the lime Tilia cordata, was studied in Moscow, Nizhny Novgorod, Kazan, Yekaterinburg, and Tyumen cities in 2016-2017. Thirteen species of parasitoids of Ph. issikii were revealed: Pnigalio agraules, P. pectinicornis, P. soemius, Sympiesis gordius, S. sericeicornis, Cirrospilus lyncus, C. pictus, Hyssopus geniculatus, Chrysocharis laomedon, Ch. nephereus, Achrysocharoides altilis, Minotetrastichus frontalis (Eulophidae), and Pholetesor circumscriptus (Braconidae). The species A. altilis was recorded as a parasitoid of the lime leafminer for the first time. The mortality rate of Ph. issikii due to parasitoids was negligible, ranging from 1.4 ± 0.4% in Kazan to 15.5 ± 2.4% in Tyumen.
