Distribution of fly species of veterinary importance in Basilicata region (Italy)

Livestock farms are prominent realities in Basilicata region (Italy), for which parasitological maps were already completed, in collaboration with the Associazione Regionale Allevatori Basilicata (ARAB), allowing the identification of the most relevant epidemiologic and etiologic aspects affecting production. Here we further expand this effort, focusing on the detection and identification of Diptera of veterinary importance. During 2020, a preliminary mass trapping program was carried out in 217 farms, using specific baits for sponging flies. The identification of captured individuals, carried out on morphological basis, allowed the identification of 7 major species. Among these, Musca domestica was the most widely distributed, while the smaller house fly (Fannia canicularis) was identified in samples from only two farms. Most of the identified flies belong to Calliphoridae family (green- and blue-bottle flies, blowflies). The species found can affect the animal welfare to a various extent, from simply annoying the animals to causing important myiases or other disease, like the Sheep strike. These problems have been largely prevented so far by good practices promoted by ARAB staff, which allowed to keep these insects under control. However, it is essential to implement a continuous monitoring to update population maps of these insects, as a basis for developing targeted and effective IPM (Integrated Pest Management) strategies.
