Changes of Coleopteran pests in agricultural, horticultural and ornamental plants during the 20th century

Abstract

Results of an analysis of coleopteran pests in agricultural, horticultural and ornamental plants during the 20th century are given. About 115 Coleoptera taxa were registered as pests of these plants (1.9% of all species known in the Czech Republic). Of these ca 20-25 species caused regular and important and other 40 species occasional and local damages. The remaining (ca 50-55) species appeared to be economically nearly or quite irrelevant. Only small changes in the composition of important coleopteran pests
were registered during the century.
