Abstract

The invertebrate herbivore communities of Heracleum sphondylium, native to Switzerland and Western Europe, and of H mantegazzianum, an introduced invasive weed originating from the Caucasus, were compared at several locations in Bern, Switzerland. The aim of this study was a comparative description of the native fauna of both plants, and an evaluation of that of the native weed for potential species for biological control of the invasive weed. A total of 42 phytophagous arthropod species was found, 34 on H sphondylium and 34 on H mantegazzianum. The arthropod guilds of 26 phytophagous species being common to both plant species were very similar. Nine species (2 mirid bugs, 1 cicadellid, 2 aphids, 1 curculionid beetle, 1 oecophorid moth, 2 agromyzid flies) were specific to Apiaceae, the remaining species were polyphagous. The herbivores attacking above-ground organs did not have a major impact on the growth of H mantegazzianum. The weevil Liophloeus tessulatus, however, causes root damage and deserves further investigations as a potential biological control species.

Kurzfassung

Die Herbivorenfauna von Heracleum sphondylium, einer in der Schweiz und in Westeuropa einheimischen Art, und von H mantegazzianum, einer eingeführten Problemart aus dem Kaukasus, wurde an mehreren Standorten im Raum Bern untersucht. Ziel der Studie war ein Vergleich der einheimischen Fauna beider Pflanzenarten, um das Potential der Herbivoren auf der einheimischen Art für die Bekämpfung der invasiven Art abschätzen zu können. Insgesamt wurden 42 phytophage Arten gefunden, je 34 an H sphondylium und an H mantegazzianum.
