PARASITIODS (HYMENOPTERA, EULOPHIDAE, BRACONIDAE) AS A MORTALITY FACTOR FOR THE LIME LEAF MINER (<i>PHYLLONORYCTER ISSIKII</i>, LEPIDOPTERA, GRACILLARIIDAE) IN TRANS-URALIA AND WESTERN SIBERIA

Abstract

The assemblage of hymenopteran parasitoids associated with the invasive lime leaf miner, Phyllonorycter issikii (Lepidoptera, Gracillariidae) developing on the lime (Tilia cordata) was studied in the Kurgan Province (Madvezh’ye Lake), and in the cities of Tobolsk, Omsk, and Novosibirsk during 2018−2019. Twenty-one species of parasitoids of Ph. issikii were recognized: Pteromalus sp. (Pteromalidae), Cirrospilus diallus, Elachertus sp., Hyssopus geniculatus, H. nigritulus, Pnigalio mediterraneus, Pnigalio sp., Sympiesis dolichogaster, S. gordius, S. sericeicornis, Chrysocharis laomedon, Ch. pentheus, Ch. pubicornis, Ch. viridis, Chrysocharis sp., Neochrysocharis formosus, Minotetrastichus frontalis (Eulophidae), Colastes braconius, Apanteles sp., Pholetesor circumscriptus and Cotesia sp., (Braconidae). Chrysocharis viridis has been reported as a parasitoid of lime leaf miner for the first time. The role of the complex of parasitoids in the mortality of the miner is negligible, the mortality rate ranging from 1.9 ± 0.4 (Novosibirsk) to 23.7 ± 3.3% (Omsk).
