The reduction in a population of the Colorado beetle (Leptinotarsa decemlineata Say) was investigated in natural conditions on the basis of the course of the fluctuation in numbers on two potato cultures excluded from the chemical control. The natural reduction of the Colorado beetle larvae reaches 93% of the initial number of eggs. The intensity of reduction increases during the season. The reduction of larvae is directly proportional to their density and invertly proportional to the degree of aggregation.
