To further understand interactions between myxomycetes and Collembola, we investigated food preferences of Collembola for myxomycete plasmodia and their responses to Collembola. We cultured two myxomycete species (Physarum melleum and Diderma sp.) and two Collembola species (Vitronura pygmaea and Ceratophysella denticulata) in different combinations for 20 d. Vitronura pygmaea consumed plasmodia, whereas C. denticulata did not consume living plasmodia, but did consume waste slime sheaths on their slime tracks. Physarum melleum fragmented frequently in the presence of V. pygmaea. These results suggest that V. pygmaea feeds on living plasmodia, whereas C. denticulata can utilise plasmodium waste products. Fragmentation may result in the escape of some fragments from consumption by V. pygmaea.

为了进一步了解粘菌和Collembola之间的相互作用，我们调查了粘菌对纤溶酶原体的食物偏好及其对Collembola的反应。我们以不同的组合培养了两种粘菌种（Physarum melleum和Diderma sp。）和两种Collembola种（Vitronura pygmaea和Ceratophysella denticulata）培养了20天。格氏酵母（Vitronura pygmaea）消耗了疟原虫，而C. denticulata则没有消耗活的疟原虫，但确实消耗了其污泥轨道上的废泥鞘。在pygmaea的存在下，mellaum经常破碎。这些结果表明梨果以活的疟原虫为食，而C. denticulata可以利用疟原虫废品。碎片化可能会导致某些碎片从pygmaea消耗而逃逸。
