  1. Increase crop diversity

    A site comparison study in 1988 near Ghent, Belgium (Desender & Alderweireldt 1990) found more ground beetles (Carabidae) and more ground beetle species in a maize Zea mays field in crop rotation than in maize or perennial ryegrass Lolium perenne fields grown in monoculture. On the crop rotated maize field, 3,500 ground beetles of 18 species were caught, compared to 3,000 beetles of 15 species on the maize monoculture field. Fourteen species were caught on the rye grass monoculture in a different year. Ground beetles were collected every fortnight from six pitfall traps in each field, from May until September 1988 (1980 for the rye grass monoculture). Fields were small, just a few hectares in size.
