The article shows the data of changes in the species abundance and vertical distribution of insecticides "Karate", "Decis profi" and "Aggivo" in the soils of the Gay-Gel National Park. The toxic effect on the soil infusoria of all three insecticides studied by us manifests itself within a day after their treatment of control sites. The decomposition of the insecticides studied by us in the soil, i.e. the weakening of their toxic effect, is also different. For example, the increase in species abundance after the treatment of "Karate" begins only on the 7-8 day of the experiment. The decomposition of the drug "Decis Profi" becomes noticeable on the 5-6 day of the study, and the least toxic of the drugs studied by us "Aggivo" loses its effect after 3-4 days of exposure.
