The article presents the results of research conducted by the authors on the territory of the Ile-Alatau State National Natural Park in 2020-2021. Research works are devoted to the fauna, biology and ecology of beetles or beetles on the territory of this natural park. Coleoptera are the largest group of insects, which is of great practical importance. They are distributed on the territory of the IleAlatau GNPP. Most of the beetle species are zoophages, and phytophages also predominate. When collecting the material, standard entomological methods were used-collection with an entomological filter, collection with an artificial light source, manual collection, etc. As a result of the conducted research, 47 species from 10 families of the coleoptera order were collected on the territory of the Ile-Alatau State National Natural Park: Meloidae, Curculionidae, Buprestidae, Chrysomelidae (out of 8 species, 17%), Tenebrionidae, Cerambycidae, Scarabaeidae (of 3 species, 7%), Coccinellidae, Silphidae, Сarabidae (of 2 species, 4%). In this order, predatory beetles are nutritionally related: representatives of the family Coccinellidae, Carabidae, the remaining species from 8 families (Meloidae, Curculionidae, Buprestidae, Chrysomelidae, Tenebrionidae, Cerambycidae, Scarabaeidae, Silphidae) are phytophages. Coleoptera are divided into zoophages (4 species), phytophages (41 species), coprophages (1 species), saprophages (1 species) by nutritional connection. Coleoptera on the territory of the Ile-Alatau State National Natural Park differ into chortobionts (27), dendrobionts (17 species), herpetobionts (3 species). Beetles in the park are ecologically mesophilic species.
