In the conditions of the Republic of Belarus there was analyzed the expediency and advantages of carrying out the wireworm (Elateridae) monitoring with the help of pheromone traps for determining the elaterid number, their harmfulness forecast and the expediency of the insecticidal action seed dressers application is substantiated in the article. The results of production trustworthiness examination of forecasted parameters and the examples of rational rate of insecticide application are stated. In course of the study there were presented coefficients of elaterid harmfulness for the calculation of the percentage of affected plants of maize (Zea mays) taking into consideration the weather conditions at the vegetation period. The application of the proposed model made it possible to obtain authentic information on the one hand, and to lower the labour intensity on the other. Also, it made it possible to predict the number of harmfulness of larvae of beetles, and to ralize economically feasible activities on agricultural crops protection against wireworms.
