Effects of change land use on aeromicological spectrum

The article presents the results of the assessment of the impact of land use changes, in connection with the accession of Kyrgyzstan to the EEC, on the quantitative and taxonomic composition of fungal spores in the air of Karakol. Aerobiological studies were carried out by the volumetric method using a 7-day Lanzoni trap, placed 13 meters above the ground. For the effective identification of fungal spores under a light microscope, a dichotomous determinant of fungal air spores was created. The aeromicological regime was formed by 9 taxa in 2015 and 18 dispute taxons in 2016, of which the dominant spectrum consisted of: spores of Cladosporia and Alternaria recorded in the air for the entire observation period. In terms of the frequency of occurrence of aerospores, the third taxon was the Fusarium. The expansion of agricultural land, increasing the range of crops grown and the growth of phytopathologies in the Issyk-Kul region resulted in an increase in the number of spores taxons in the air and spores of rust and smut fungi (tilletions, sporosporia and puccinia) not previously defined in aerobiological samples.
