[ES] Debido a la frecuencia con que se encuentran en la naturaleza moluscos albergando dos o más especies de Protostrongylidae, se han probado experimentalmente y de forma simultánea con larvas de Muellerius capillaris y Neostrongylus linearis, 6 especies de moluscos Helicidae. Para seguir el desarrollo larvario conjunto de ambos parásitos, se utilizaron sobre 40 moluscos adultos de cada especie, que se mataron seriadamente a partir del 6º día pi. De los resultados obtenidos referentes a las larvas I que penetraron en cada molusco, y las que de ellas prosiguieron a L-ll y L-lll, así como los períodos de tiempo que requirieron para ello, consideramos que el orden de idoneidad de las especies de moluscos probadas, para el desarrollo larvario conjunto de M. capillaris y N. linearis, fue: Cernuella (Xeromagna) cespitum arigonis, Cochlicella barbara, Helicella ordunensis, Cepaea nemoralis, Helicella (Helicella) itala y HeIix (Cryptomphalus) aspersa. Parece que M. capillaris y N. linearis evolucionan mejor en las infestaciones dobles que en las monoespecíficas.
[EN] Due to the fact that molluscs harbouring two or more species of Protostrongylidae are frequently found in natural habitats, 6 species of Helicidae molluscs were experimentally infected on with Muellerius capillaris and Neostrongylus linearis larvae. Approximately 40 adult molluscs of each species were proved and killed in series from the 6th day post-infection, so that the joint larval development of both parasites could be followed. The results referring to the larvae I which penetrated each mollusc and those of them which reached to L-ll and L-lll, as well as the time required to do so, make us think that, from amongst the molluscs species investigated, the most suitable for the joint larval development of M. capillaris and N. linearis are in decreasing order: Cernuella (Xeromagna) cespitum arigonis, Cochlicella barbara, Helicella ordunensis, Cepaea nemoralis, Helicella (Helicella) itala and HeIix (Cryptomphalus) aspersa. It seems that M. capillaris and N. linearis evolve better in double infections than in the monospecific one.
