ABSTRACT The article provides information on the species composition and reproduction of odonata larvae in the lakes and ponds of vicinity Kura, the results of the 2012-2017 studies. Odonata larvae form the basis of fish food that is essential for wild, especially predatory fish. The main purpose of the research is to study the species composition and number of odonata larvae in lakes and ponds of vicinity Kura. Ponds more often found in downstream of the Kura river. We are going to talk here about the ponds of vicinity of Kura river. It is known that rivers, especially large rivers, can be affected by various natural factors - strong flood waters, soil crashes or landslides, earthquakes, volcanic eruptions, etc. From time to time under the influence of these type of natural factors, it changes its home bed and the process is still ongoing. People are playing a great role in these processes such as construction of hydroelectric power stations, change of riverbed, etc. In the process of changing river basins, independent water reservoirs or streams are often formed in or around the river's old bed. Water leaks formed in this way or other are either linked to the river or completely cut off from the main source. Thus, the ponds are an aquatic ecosystem been formed in the riverbed or in adjacent areas. There were several dozen of such ponds on the banks of the Kura and Araz rivers, especially in Yevlakh, Imishli, Kurdamir, Sabirabad and other districts. Since, the 50s of the 20th century, as a result of the regulation of the Kura and Araz rivers, most of the streams have dried up, while the water regime has changed dramatically.
