摘要

Aquatic insects are very important due to their ability to serve like environmental bio-indictors. In this study, we evaluated the actual environmental situation of ecosystem in the Ishemi and Shkumbini river deltas, by analysing the biodiversity of dragonfly (pilivesa) Odonata (order Odonata, class Insects, type Arthropoda). The biological material was collected during the period 2007-2008. Data collected have figured out on both areas: 23 species, 15 genera and 8 families of Odonata. The most represented group is Anisoptera with 15 species and frequency 62.51%. The Libellulidae is the most represented family with 8 species and frequency 34.78%. The ecosystem surrounding the Shkumbini delta river shows a higher diversity, properly with 18 species and frequency 78.26%, while those of the ecosystem of Ishemi delta river present a lower diversity, of 10 species and frequency 43.47%. That is an indication that the Ishemi delta river is more polluted compared to that of the Shkumbini delta river, hence not offering optimum conditions for Odonata species, which look for highly conservation habitats. In both areas are encountered only 6 common species, and the 'Jaccard index of similarity coefficient' was 26.08%, which is an indication of different conditions of environmental quality for these bioindicator species.
