New and little-known invertebrate species that damage the cultivated apple tree (Malus domestica) and the sivers apple tree (Malus sieversii) in the southeast of Kazakhstan. Message 1. Mollusca

The article presents new data on the composition, abundance, and distribution of harmful malacofauna of apple orchards and Sivers apple tree growing areas in the southeast of Kazakhstan. In total, 11 harmful species of mollusks belonging to 5 genera from 4 families of the Stylommatophora order of the Gastropoda class were noted. Most of them (8 species) belong to the families Camaenidae and Agriolimacidae (4 species in each family). The remaining 2 species belong to the Succineidae family and 1 species belongs to the Geomitridae. 4 species - Fruticicola almaatini (Skvortzov, 1940), Deroceras reticulatum (O. F. Müller, 1774), Novisuccinea martensiana Nevill, 1878 and Oxyloma elegans (Risso, 1826) - were not previously noted as organisms that harm the cultivated apple tree and the Sivers apple tree. The most numerous, harmful and widespread are the garden snail Fruticicola lantzi (Lindholm, 1927) and the reticulated slug D. reticulatum. Local damage during mass reproduction can be caused by the snail F. almaatini, the slender amber O. In addition to the above-mentioned gastropods, the following species of mollusks have been observed in the growing areas of cultivated apple and Sivers apple trees: Turanena tenuispira Schileyko, 1984, Pseudonapaeus entodon (E.v. Martens, 1882) (Enidae), Punctum pygmaeum (Draparnaud, 1801) (Punctidae), Zonitoides nitidus (müller, 1774) (Gastrodontidae), Macrochlamys lessini Westerlund, 1902, M. turanica Martens, 1874 (Ariophantidae). Their number is very low, and the economic significance for the cultivated apple and Sivers apple trees is unknown and requires clarification.
