For studying of distribution and specific structure of snapping beetles examination of corn crops were spent. As observation has shown, presowing seed dressing by a preparation Gaucho, (4-5 l/t) provides protection of seed, sprout, roots and above-ground parts from pests. Term of protective action: minimum - to a phase of 5-6 leaves, maximum - to 7-8 leaves of corn. Preservation of the planned density of culture standing during the period shoots - 5 - 8 leaves makes 80-95%. This preparation decreases crop losses at late damage and increases productivity on 30-40%. Biological efficiency on lodged plant makes 70-80%. Under the influence of the preparation there was a number decrease of wireworm at the expense of larvae of 1st and 2nd years of a life. Application of insecticides of system action in a kind of seed dressers does not render negative influence on number and abundance of carabids and other predatory arthropods. For field purification from pests it is necessary to make within 2-3 years seeding of cultures by the seeds processed by insecticides
