摘要：

Insect communities on 5 introduced and 5 indigenous plants at locations near Gottingen (Germany) were compared. Indigenous and introduced plants were alike with respect to their high abundance, architecture (mean hight: 113cm) and in three cases, taxonomy (the same genus: Heracleum, Impatiens, Matricaria, see tab. 1). On introduced plants the number of parasitoid species decreased more than the number of phytophagous species (Fig. 1). Furthermore density of phytophagous insects was found to be lower (Fig. 2+3). Release from herbivory is discussed as reason for the successful invasion of non-indigenous plants. Neophyte stands appeared to be characterized by (i) only few insect species and (ii) reduced proportions of natural enemies.
