Biodiversity of certain invertebrates (Insecta, Molluska) of the Azat River gorge, Armenia and their bioecological features

Aim . The aim of the work is to study biodiversity certain invertebrates (Insecta, Molluska) Azat River gorge and their ecological biological features. Material Methods Invertebrates collected in Garni‐Goght‐ Geghard section period from 2015 2021 served as material. was carried out at Scientific Center for Zoology Hydroecology National Academy Sciences Republic Armenia. Our own collections have been used material, well insects mollusks Institute Zoology. Results As a result studies species composition (Geghard, Goght, Garni) we found: 25 horseflies (Tabanidae: Diptera), 24 phytophagous gall midges (Cecidomyiidae: Diptera); 13 aphid (Aphididae: Hymenoptera); 17 pyralid moth (Crambidaе: Lepidoptera) 5 subfamilies (Crambinae, Evergestinae, Pyraustinae, Spilomerlinae, Glaphyriinae); 19 (Molluska): 3 freshwater families (Physidae, Planorbidae, Ancylidae), 16 terraneous 10 (Succineidae, Vertiginidae, Orculidae, Pupillidae Valloniidae, Enidae, Vitrinidae, Endodontidae, Limacidae, Helicida). bioecological features these studied distribution by biotopes, revealing changes some groups due anthropogenic factors. Conclusion researches undertaken, wide variety has frevealed. They occupy all niches are found plant formations gorge. Most insect economic importance. Research on river very promising. Works this direction will be continued with involvement new research groups.
