Introduction
I am working with several ongoing projects for now: a) Biodiversity of small insects in Norway, I am identifying Encyrtidae, Aphelinidae and Coccoidea; b) I am in charge to sort and organize identification of Hymenotpera in the new project of Caucasus Barcode of Life; c) Biodiversity of Hymenopterans in Lagodekhi protected areas; d) To study potential of biocontrol of Halyomorpha halys in Georgia; e) A study of SpotedWingDrosophila(SWD) new dangerous pest in Georgia, distribution and dynamics.
