| Résumé : |
"In 1992 and 1993 a number of species and individuals of hoverflies, butterflies, wild bees, and threadwaisted wasps in sown weed strips, adjacent fields and a field boundary were investigated in the Swiss plateau near Bern. Insects were directly observed and quantified visually, and caught with yellow pantraps. Observations always revealed distinctly higher numbers of species and individuals in weed strips than in adjacent fields, but in yellow pan traps, opposite results or at least less distinct differences, were noted for some insect groups. In 1992, the two-year-old weed strip contained more species of hoverflies, butterflies and wild bees than the one-year-old strips. This was probably due to the more diverse supply of flowers in the two-year-old weed strip which contained both annual and perennial plants. Weed strips provided suitable nutritional conditions for flower visiting insects and were there¬ fore very attractive habitats for all insect groups investigated in this study." (source : auteur) |
