Plant nectar flower mixture/wildflower strips
A replicated, controlled study in June to October 1985-1986 and February to August 1987 in a winter wheat field in north Germany (Nentwig 1989) could not detect consistent differences in arthropod numbers between sown flower strips (1 m-wide), winter wheat strips (12 m-wide) and the winter wheat control field. The number of arthropod pest species, weed species cover and crop yield did not differ significantly between the strip types. Arthropod abundance varied greatly over the season, between years and between trapping methods. Five flower strips (1 m-wide, each separated by a 12 m wheat strip) were sown in 1.2 ha of a 1.8 ha arable field with a seed mix containing Crimson clover Trifolium incarnatum, red clover T. pratense, lupin Lupinus angustifolius and winter rape Brassica napa in May 1985 and 1986. The remaining area of the same arable field was used as a control. Arthropods were sampled using pitfall and yellow bowl traps in all three treatments throughout the season in all three years. Plant biomass, vegetation cover, weed species composition and frequency were monitored monthly.
