DEFINITION OF THE PESTS' SORT STRUCTURE IN POTATO SOWINGS OF THE WESTERN REGION OF THE AZERBAIJAN REPUBLIC

Growing of the potato plant in the western region of the Azerbaijan Republic for more than 200 years caused collection of the representatives in the fauna and flora concerning the different sorts in agrocenosis. An aim of the research is to work out fight measures integrated to the local condition against the pests in potato sowings of the zones above sea-level, specifying a sort structure, spreading area and biological features of the pests. The route observation-calculation works were performed by involving 30 % of agrocenosis for specifying the pests’ sort structure in potato sowings of the western region in 2003-2022. Our researches showed that 31 sorts of the pests spread in potato sowings which are grown in the zones 850-900 meters above sea-level (Gryllotalpa gryllotalpa L., Gryllus desertus Pall., Dociostaurus maroccanus Thnb., Chaetocnema breviuscula Fald., Leptinotarsa decemlineata Say., Anisoplia leucaspis Cast,Melolontha pectoralis Germ, Agriotes gurgistanus Fald and others). An injury of the pests involves underground (mole cricket and wire worms) and surface (Colorado beetle and its larva) organs. 27 sorts of the pests were revealed in agrocenosis while descending 900-1000 meters above sealevel. During the researches aren’t found in the zones above 1000 meters. Change of the pests’ sort structures depending on geographical zone was determined.
