This list includes pests that damage forest trees in any way, which could otherwise be used for economic purposes. These may be trees in forests, parks, or even free-standing trees. Saprophages, which help decompose already decaying wood left in the forest, are not included here. These are mostly bark beetles (Cucrulionidae), longhorn beetles (Cerambycidae) and jewel beetles (Buprestidae). You may encounter many of these pests at home when they hatch in wood you have stored for fuel.
The following paragraphs explain the individual columns in the table below.
The data sources used to create the individual tables can be found in the menu "About project" -> "Sources"
.
Family/Taxon and English name
The names of the families have been modified according to the family catalogue, which is available on this website as of 8 March 2026.
The names of the taxa themselves have been adjusted according to the catalogues of the relevant families on this website, valid as of 8 March 2026. If a taxon appears in the table that is not included in the catalogue of the relevant family (e.g. it is a non-native species that was not included in the family catalogue when it was created), the name of such a taxon was taken from the currently valid ITIS (Integrated Taxonomic Information System) database.
Given that pests very often also have Czech names, the more commonly used or established names are also used in this table.
Damage
The data in this column specify the appearance of the pest. The data can take one of the following values:
| Value | Description |
| larva | The pest is the larval stage of the beetle. |
| imago | The pest is the adult beetle. |
| larva (roots), larva (leaves), imago (roots), imago (leaves) | The pest is the larva or adult, with a more detailed description of where that stage causes damage. |
| larva(!), imago(!) | The pest is the larva or adult, with an emphasis on which form is more dangerous (harmful). |
Plant
This column contains a list of plants that are damaged by the given species. For some highly polyphagous species, such a list would be too long. In such cases, the list is shortened and ends with several dots (...). The column contains the Czech names of plants as they were recorded in the individual sources studied.
Location of damage
-
This column specifies the locations where the taxon causes the most damage to the plant. In the case of forest trees, the most frequently mentioned locations are:
- stump (the taxon develops in stumps)
- roots (the taxon damages roots; feeding or development)
- trunk, base of trunk, stem
- bark (development just below the bark or the taxon gnaws on the bark of young shoots)
- phloem (the taxon disrupts the phloem of the plant - interrupts the flow of sap)
- branches (weaker and stronger branches of the tree)
- crown (development occurs in the upper part of the tree, in the crown)
- leaves (the taxon damages leaves or needles by gnawing)
- flowers (the taxon damages the flowers of the plant)
- buds (the taxon gnaws on the sprouting buds of the plant)
- fruits (the taxon damages fruits or cones)
EPPO Code
The EPPO global database is managed by the Secretariat of the European and Mediterranean Plant Protection Organisation (EPPO). The aim of the database is to provide all information on specific harmful organisms that EPPO has created or collected. The database contains information on more than 98,700 species of interest to agriculture, forestry and plant protection: plants (both cultivated and wild) and pests (including pathogens and invasive alien plants). The database also contains detailed information on more than 1,900 species of harmful organisms that are subject to regulatory interest (harmful organisms listed by the EPPO and the EU, as well as pests regulated in other parts of the world).
Alien
This column indicates whether the taxon is non-native to the Czech Republic. The flag was set according to the source from which the information was drawn and may not correspond exactly to the table in the Lexicon -> Invasive Species menu, where a number of species are marked with the code C (uncertain origin) in the "Origin Status" column and are marked as native or non-native in the list of pests.
Note
The last column is used for comments that specify or justify the classification of a given taxon as a pest.
