DescriptionCurculionidae developing in the soil of birch stands in an air-polluted region were classified using the method of soil photoeclectors on the basis of their population dynamics (1986-2000) and phenology of their emergence from where they developed. In the course of 15 years we saw two evident culminations in the population density of Polydrusus undatus, while the population density of the other species - Polydrusus (Metallites) impar, Phyllobius arborator, P. argentatus, P. calcaratus, Rhinomias forticornis and Strophosoma capitatum culminated only once. We derived the sum of effective temperatures, which characterize the start of activity of a wide range of weevils. Based on the phenology of emerging from where they developed, the dominant species were those weevil species that are active in the spring.
