- Abstract
An analysis of the current harmfulness of moths and butterflies (Lepidoptera) in Czechia was carried out. In total, about 50 species (1.4% of the Czech fauna) of regular or at least occasional pests with a not insignificant economic importance are registered. Of these, 16 (30%) damage field and garden crops, 15 (28%) fruit trees and grapevine, 7 (13%) ornamental greenery, 6 (12%) forest trees and 9 (17%) stored materials. The causes of possible changes in species composition and pest abundance are briefly discussed. The species spectrum of pests has clearly narrowed over the last decades. The loss of harmfulness has usually occurred in less significant, but also in some formerly important pests. The increase of new pests is minimal. In the last 30 years, two newly introduced harmful nonnative (invasive) species (Cameraria ohridella and Cydalima perspectalis) were recorded (4 since the mid-20th century). No new Lepidoptera pests have been registered during this period, which have spread spontaneously into Czechia, e.g. due to climate change.
