Wireworms in arable farming

Damage caused by the larvae of the click beetle has become increasingly frequent and fierce in recent years. In spring wireworms become more active to search for food. By doing this, the wireworms can cause severe damage to different crops. There are different simple methods to monitor the population of wireworms in crop fields.

The wireworm is the larva of the click beetle. From May to June these beetles lay their eggs in grass fields, wheat fields and several other crops. The wireworm lives three to four years in the ground after which it pupates. This pupation takes place in August. In spring the wireworms become active to search for food. They reach to the upper part of the soil and starts feeding themselves from young crops. The wireworm is around two centimetre and has tree pairs of legs. Most damage from the wireworms occurs in the root collar of the plants, just under the soil. Young plants, among which lettuce, cabbage, chicory, sugar beets and corn, wither and eventually die. Potatoes and carrots cannot be sold due the holes caused by the wireworms.
