Abstract

Invasive species have to overcome the biotic resistance of the environment for successful distribution in the secondary range; this resistance can be effectively made by unspecialized phytophages. We carried out a series of laboratory experiments on studying the ability of generalist phytophages, such as terrestrial mollusks, to feed on invasive goldenrod species (Solidago canadensis L. and S. gigantea Aiton). A significant number of terrestrial mollusks of six species were found on the stems and leaves of goldenrods; however, the results of laboratory experiments have shown that most of them cannot consume this plant as food, and Fruticicola fruticum (O.F. Müller) (Bradybaenidae) and Deroceras sp. (Agriolimacidae) do not choose goldenrod when there are other alternatives, although they can potentially feed on goldenrod. Therefore, snails and slugs in natural populations have a negligible effect on the vital activity of S. canadensis and S. gigantea and cannot suppress the expansion of these species.

莫斯科州陆生软体动物以固醇类(S. canadensis和S. gigantea)的入侵物种为食的能力。

摘要

外来入侵物种必须克服环境的生物抗性才能在次级范围内成功分布。这种抗药性可以通过非专业的噬菌体有效地产生。我们进行了一系列实验室实验,以研究通配性噬藻类(如陆地软体动物)以入侵金毛golden种(加拿大一枝黄花 和 S. gigantea  Aiton)为食的能力。在金毛的茎和叶上发现了大量的六种陆生软体动物。然而,实验室实验的结果表明,它们中的大多数不能将这种植物作为食物食用,而 Fruticicola fruticum  (OFMüller)(Bradybaenidae)和Derocerassp。(Agriolimacidae)当有其他选择时,不要选择菊科植物,尽管它们可能会以菊科植物为食。因此,自然种群中的蜗牛和对加拿大链球菌和 巨型链球菌的生命活动影响可忽略不计,并且不能抑制这些物种的扩张。
