The Monitoring of Raspberry Pest Species Composition in the Conditions of the Ijevan Region

Abstract

There are many berries grown in Armenia, but raspberries are among the most popular. Several pests, the
species composition of which has not yet been determined, hinder the achievement of a high-quality harvest. Raspberry
(Rubus idaeus) pest species composition was monitored in Tavush marz (Ijevan community) in 2022-2023. Our research
has identified and registered seventeen types of pests, of which two belong to the Acarina order of the Arachnoidae class
and fourteen to the following orders of the Insecta class: Thysanoptera, Homoptera, Orthoptera, Coleoptera, Diptera,
Lepidoptera, Heteroptera, one in the Gastropoda order of Mollusca class. The detected pests were: Tetranychus urticae
(Koch, 1836), Eriophyes gracilis (Nalepa, 1891), Thrips tabaci (Lindeman, 1899), Aphis grossulariae (Kaltenbach,
1843), Myzus persicae (Sulzer), Stictocephala bubalus (Kopp and Yonke, 1977), Gryllotalpa gryllotalpa (Linnaeus,
1758), Tettigonia viridissima (Linnaeus, 1758), Byturus tomentosus (De Geer, 1774), Anthonomus rubi (Herbst, 1795),
Melolontha hippocastani (Fabricius, 1801), Polyphylla olivieri (Castelnau, 1840), Resselie llatheobaldi (Barnes),
Lasioptera rubi (Schrank, 1803), Pennisetia hylaeiformis (Laspeyres, 1801), Dolycoris baccarum (Linnaeus, 1758),
and Deroceras agreste (Linnaeus, 1758). Nevertheless, the most spread species were Resselie llatheobaldi (Barnes),
Lasioptera rubi (Schrank, 1803), Anthonomus rubi (Herbst, 1795), and Byturus tomentosus (De Geer, 1774).
