Pests

Wireworm

Elateridae

Wireworms are the larvae of click beetles that inhabit the soil and damage plant roots, stems, and tubers. Varietal resistance to them is a relative indicator based on field trial results rather than genetic immunity.

Mentioned in descriptions 30 varieties reference book.

Wireworms are the larvae of click beetles from the Elateridae family, characterized by a long life cycle of 3 to 5 years. They inhabit the soil and migrate vertically depending on weather conditions, with their damage potential increasing during dry periods. Damage manifests as stand thinning due to the gnawing of stems and roots, as well as the presence of tunnels in tubers, which reduces marketability and promotes the development of secondary infections.

The concept of wireworm resistance does not imply immunity and is a measure of relative susceptibility. The nature of this phenomenon is not sufficiently understood and is determined by a combination of agro-ecological factors, plant morphological traits, and biochemical composition. There is no unified international coding system for resistance to this pest; therefore, variety descriptions use terms such as 'relatively resistant' or 'slightly susceptible'.

Evaluation of varietal resistance is conducted by scientific institutions based on criteria such as the percentage of damaged tubers and the average number of tunnels per 100 tubers compared to susceptible check varieties. To select suitable planting material, agronomists are advised to rely on regional susceptibility lists compiled from the results of official variety trials and field observations in specific cultivation zones.
