New Parasitoids of Leucoptera sinuella (Reutti) (Lepidoptera: Lyonetiidae) in Bulgaria

摘要

In 2018, the parasitoid complex of Leucoptera sinuella (Reutti) (Lepidoptera: Lyonetiidae) was studied in two localities (town of Banya and Voinjagovo village) near Striama River in Central South Bulgaria. Larvae and pupae of L. sinuella were periodically collected in poplar (Populus spp.) plantations and studied in laboratory conditions. As a result, four eulophids (Hymenoptera: Eulophidae) were identified: Baryscapus endemus (Walker), Chrysocharis pentheus (Walker), Cirrospilus pictus (Nees) and Pediobius bruchicida (Rondani). Three species (B. endemus, C. pentheus and P. bruchicida) were established for first time in the parasitoid complex of L. sinuella. The most abundant species was B. endemus (86.1%), followed by P. bruchicida (9.7%), C. pictus (2.8%) and C. pentheus (1.4%). The mortality of the host caused by the parasitoids in different samples varied between 0 and 76.7%, with an average of 10.0%.
