RESUMEN
Cutaneous myiasis in Australian sheep became an increasing problem in the early years of the 20th century after the import of the wrinkly Vermont Merinos and the introduction of Lucillia cuprina. WE Abbott, a successful pastoralist in New South Wales at that time, wrote a little-known and unusual description of early methods of control: a parody based on an episode in Through the Looking Glass by Lewis Carroll. The plight of struck sheep and the lives and times of Abbott, several other pastoralists and the entomologists of the New South Wales Department of Agriculture are illuminated as the Walrus and the Carpenter walk again across the hills and pastures of New South Wales.

From a study carried out in 22 townships of the Etnean area, by interviewing 112 shepherds, it was confirmed that 90 of them (80.3%), once or more in their lives, had contracted myiasis by Oestrus ovis L., habitual agent of estriasis in sheep. The most frequent sites of involvement were the pharynx (77 times), often extending to the larynx, the conjunctiva (56), followed by the nose (32) and rarely the ear (1). Multiple simultaneous sites involvement was also frequent affecting 54.4% of the shepherds. The chief symptom was pain, sometimes accompanied by fever and malaise. The shepherds go rarely to see a doctor (only 7 out of 90), the greater part preferring traditional remedies. It is curious to note that myiasis associated with Oe. ovis was already observed more than 150 years ago by a Sicilian physician, G. A. Galvagni, who had pointed out the high incidence of the myiasis in shepherds in the area. The persistence of human myiasis in the Etnean area appears to be related to the fact that in this region the conditions of sheep farming and the lifestyle of shepherds have not changed so much since then.

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.

A case of external ophthalmomyiasis by Oestrus ovis is recorded from Provence-Côte-d'Azur (France). The patient has been constaminated on the Nice beach far away from the breeding areas of sheep and goats which are the usual host of this fly. One larva specimen, which was found in the patient's eye, is described and compared to the larva of Rhinoestrus purpureus, another agent of external human ophthalmomyiasis.
