Diversity protects plant communities against generalist molluscan herbivores

Wildflower strips are used to increase natural enemies of crop pests and to con- serve insect diversity on farmland. Mollusks, especially slugs, can affect the vege- tation development in these strips considerably. Although recent theoretical work suggests that more diverse plant communities will exhibit greater resistance against herbivore pressure, empirical studies are scarce. We conducted…

After the invasion of the gall wasp in Ticino’s chestnut forests, cantonal authorities sought an homologation of T. sinensis by the Federal Office for the Environment.
