Lasius neglectus Van Loon et al. (Hymenoptera, Formicidae), an Invasive Ant Species in Crimea

Аннотация

Data on distribution of Lasius neglectus Van Loon et al. in Crimea are reported. The structure of foraging areas of 111 monocalic and polycalic colonies, the daily activity rhythm, and the visiting of 26 species of trees by L. neglectus workers were studied; over a third of the visited tree species were conifers. Most colonies of L. neglectus in Crimea are monocalic. No replacement of the 12 native ant species present in the territories of the monocalic and polycalic colonies of L. neglectus was observed. Invasion of L. neglectus to Crimea probably started in the early 1970s.
