Before the occupation, 53 of 280 species belonging to the fauna of longhorn beetles of Azerbaijan were recorded in the territory of Karabakh. These species belong to the following genera: Aegomorphus, Agapanthia, Asemum, Cerambyx, Certallum, Chlorophorus, Dinoptera, Dorcadion, Echinocerus, Enoploderes, Gracilia, Hesperophanes, Isotomus, Judolia, Leiopus, Mallosia, Molorchus, Necydalis, Oberea, Pachytodes, Penichroa, Phymatodes, Phytoecia, Plagionotus, Prionus, Purpuricenus, Ropalopus, Rosalia, Rutpela, Saperda, Spondylis, Stenurella, Stictoleptura, Strangalia, Stromatium, Trichopherus. Of these species, Rosalia alpina (Linnaeus, 1758), Prionus asiaticus Faldermann, 1837, Necydalis (Necydalis) ulmi Chevrolat, 1838, Mallosia (Eumallosia) herminae Reitter, 1890, Cerambyx (Cerambyx) dux (Faldermann, 1837), C. (Cerambyx) cerdo acuminatus Motschulsky, 1853 are few. R. alpina is included in the IUCN Red List and the Red Book of Azerbaijan under the VU category. Species of the genera Purpuricenus, Cerambyx, Enoploderes, Molorchus, Necydalis, Prionus, Ropalopus, Rosalia, Saperda, Spondylis, Isotomus, Judolia, Leiopus, Pachytodes, Penichroa, Chlorophorus, Dinoptera, Stictoleptura, Aegomorphus, Gracilia, Asemum, Hesperophanes, Phymatodes, Rutpela, Stenurella, Strangalia feed on the trunks of trees and shrubs, Agapanthia, Certallum, Dorcadion, Echinocerus, Mallosia, Phytoecia on herbaceous plants. Some species of Oberea and Plagionotus feed on the trunks of deciduous trees, and some on grasses. Stromatium and Trichopherus damage wooden structures. The liberation of the Karabakh lands from occupation opens up new prospects for Azerbaijani scientists to conduct research in these areas. The re-study of the entomofauna of Karabakh will create conditions for the discovery of rare and endangered species in this area.
