The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is a new pest of corn in Europe. Future management may include the use of natural enemies. Our study focused on the determination of density and species composition of spiders in corn fields, as well as in the adjacent corn field margins, during the peak flight period of WCR adults. An additional objective was to test different sampling methods, used for spider collecting, in corn fields and in adjacent corn field margins. The field study was conducted in July and August, 1999, in experimental corn plots, as well as in the adjacent field margins, owned by the Cereal Research Institute, Szeged, in Southern Hungary. Spiders were collected by individual plant search and by sweep nets.
