HELMINTH LARVAE INFECTION IN COLEOPTERANSAND DIPTERANS IN THE TASHKENT OASIS

In the studied area of the Tashkent oasis, 9 helminth larvae species belonging to cestodes (Echinolepis carioca and Choanotaenia infundibulum) and nematodes (Spirura rytipleurites, Spirura talpae, Gongylonema neoplasticum, Gongylonema pulchrum, Dipetalonema evansi, Dirofilaria immitis, Setaria labiatopapillosa) were identified. The research material was insects (Coleoptera and Diptera), and their infection with helminth larvae that parasitized vertebrates in the Tashkent oasis. The insects were collected and studied in the Akhangaran, Bostonliq, Yuqorichirchiq, Parkent, Zangiota, and Chinaz Districts and the city of Angren in spring, summer and autumn 2024. Three hundred and fifty specimens of Coleoptera (8 species) and 200 specimens of Diptera (2 species) were collected and studied to detect helminth larvae according to the common method. It was established that the occurrence of individual species of cestode and nematode larvae varied significantly in the insects. The prevalence of individual insect species ranged 1.85 to 7.14%, with the infection intensity of 3 to 15 specimens of larvae. Helminth larvae were found in beetles (Tenebrionidae, Scarabaeidae) and dipterans (Culicidae) in the Tashkent oasis. The most common species was Spirura talpae, and the least common was Echinolepis carioca.
