With the aim of more rationally wireworm control, different methods for their forecast were investigated. By standard, manual soil survey (0.25 square m), in the middle of October 2001, it was established that there were no significant differences in Elaterid species structure and population densities between optimal and two time smaller number of samples, while on three times smaller number they are. During April-May 2002, potato baits attracted two times more (47.2/square m) and a wheat and corn seed baits even 2.5-15 times more (63-382/square m) wireworms than it was found in standard soil samples (25.4/square m). In early March 2008, potato as a attractant was not successful in forecasting wireworms in sugar beet, while wheat and corn seeds were more efficient sown like triangle than single. By plant baits it is sufficiently to survey two or more times less area and four or more times less volume of soil, respectively, which is significant saving in time and labor.
