Abstract


Se compararon poblaciones y aislados de P. vulnus provenientes de distintas partes del mundo, asociados a diferentes huéspedes, en base al análisis de los caracteres morfométricos de machos y hembras. Fue establecido el grado de asociación entre el conjunto de poblaciones y aislados considerados. Se detectaron diferencias significativas de las poblaciones y aislados, eventualmente función de su origin geográfico y/o tipo de huésped al que se asocian. [Populations and isolates from different geographic regions and associated with different hosts were compared by analysis of morphometric characters of males and females. The degree of association among the isolates and populations was studied by discriminatory analysis. The majority of the characters showed significant differences. The separation of the populations and isolates was related to their geographical origin and/or the type of host with which they were associated.]
