Mapping goat warble fly distribution and related problems.

This paper analyzes the state of knowledge of the goat warble fly infestation mainly relating to its distribution and the problems that arise in mapping this infestation, namely, the long controversy on the taxonomy, the number of existing species and hosts, the scanty knowledge of some of the morphological features of various species, the presence of the different species in the same host and the same species in different hosts, the presence of the parasites in diverse geographical and zoological settings, as well as from probable misidentifications still present according even to the most recent literature. Finally, the need for a new approach to the study of the mapping that overcome the morphological analysis and the resort to more modern tests applied are advised.
