Kula Faculty of Forestry and Wood Technology Mendel University of Agriculture and Forestry in Brno Brno Czech Republic ABSTRACT In the course of 2004-2007 the effects of compensation liming at the application dose of t ha dolomitic limestone on the elimination or activation of phytophages or other types of damage resulting in the loss of assimilatory organs did not become evident yet. A shift was noted in the fluctuation expressed indirectly by the extent of damage to the assimilatory area in feeding caused by an undetermined hymenopterous larva summer increase weevils spring and summer decline and increase in 2007 Coleophora serratella decline Eriocrania sp. increase mites Acalitus rudis increase Eriophyes leionotus increase in 2006-2007 . Only signs of a positive response to higher doses of dolomitic limestone characterized the mite Eriophyes leionotus.

Changes in the chemistry of assimilatory organs of birch Betula pendula Roth after the application of dolomitic limestone became evident particularly by an increase in calcium and magnesium decrease in phosphorus and potassium and partly in manganese and cadmium Hrdlicka Kula 2007a . If some papers dealing with the impact of dolomitic limestone on soil and epigeous fauna earthworms soil mites etc. were published Huhta 1979 Hâgvar Amundsen 1981 Winter 1990 Weber Eisenbeis 1992 Rundgren 1994 Kula Matejkova 2007 then information on the response of phytophages developing on leaves sucking mining and leaf-eating is nearly missing.
