Prilog poznavanju phyllonorycer issiki (Kumata, 1963) (lepidoptera, gracillariidae) u Srbiji

Abstract

Phyllonorycter issikii (Kumata 1963) je invazivna vrsta lisnog minera poreklom iz Azije. Razvija se na biljkama iz roda Tilia. U Srbiji je prvi put pronađena 2013. godine. Njen areal se od tad proširio, i mi smo je pronašli na još pet lokaliteta, na dve vrste lipe: T. cordata i T. tomentosa. Ph. issikii je proučavan na dva od tih pet lokaliteta. Na njima je utvrđeno je postojanje dve preklapajuće generacije. Pri tom, razlike u pogledu intenziteta napada između njih nisu konstatovane. Te razlike su samo postojale između lokaliteta na kojima su istraživanja obavljena i vrsta lipe na kojima je Ph. issikii pronađen. Iz sakupljenog materijala gajenjem su dobijene dve vrste parazitoida: Pediobius saulius (Walker 1839) and Minotetrastichus frontalis (Nees 1834).

Phyllonorycter issikii (Kumata, 1963) is an invasive leaf-mining moth originating from Asia. It develops on plants from the genus Tilia. The first finding of this species in Serbia was in 2013, and since then, the range of the species has spread, and we have found it at five more localities on T. cordata and T. tomentosa. Ph. issikii was studied at two of these localities. The existence of two overlapping generations was determined. No significant differences in the intensity of the attack between them were noticed. Differences existed only between the localities where the research was conducted and between the Tilia species on which Ph. issikii was found. As regards the lime species, the moth preferred T. cordata to T. tomentosa at both localities. Two species of parasitoids were reared from the collected material: Pediobius saulius (Walker, 1839) and Minotetrastichus frontalis (Nees, 1834).
