Abstract:

Plant parasitic nematodes are harmful organisms that cause economic losses in cultivated plants. This study was carried out to determine the plant parasitic nematode species found in potato cultivation areas of Talas and Tokmok Regions located in the North of Kyrgyzstan. For this purpose, 15 plant and soil samples were taken from potato cultivation areas during the survey studies conducted in the summer of 2016. The identification of the plant parasitic nematode species obtained from the samples was made by classical methods using morphological and morphometric measurements. As a result of the diagnostic studies carried out, 4 families belonging to the Tylenchida order and 6 species belonging to 6 genera were determined. These species are Bitylenchus goffarti (Sturhan, 1966), Ditylenchus destructor (Thorne, 1945), Filenchus cylindricus (Thorne Malek, 1968), Helicotylenchus vulgaris (Yuen, 1964), Rotylenchus buxophilus and Scutylenchus rugosus (Sıddoqii, 1963). The most common species identified in the study were recorded as F. cylindricus and B. goffarti. All the species obtained are new records for Kyrgyzstan and D. destructor (potato tuber nematode) is a pest causing significant losses in the potato plant.
