Resumo(s)
Phlebotomine sandflies are important vectors of Leishmania spp. and phleboviruses causing
disease in animals and humans. Morphological identification of phlebotomine sandflies to the species
level is challenging, requiring microscopical examination of the genitalia, which is demanding and
time consuming. Molecular sandfly species identification can be a practical solution to save resources
since it enables further molecular studies capable of generating data, such as biting preferences by
blood meal analysis. In this study, resorting to a sandfly dataset collected between 2014 and 2018
across Portuguese territory under active mosquito surveillance and sandfly specific surveys, we
used molecular methods to explore the genetic diversity and spatial distribution, further exploring
ecological co-variants of four sandfly species—Phlebotomus ariasi, P. perniciosus, P. sergenti, and
Sergentomyia minuta—all of which are of public health importance. Sandflies were collected from
Spring to Autumn (May–November) following local temperature patterns. P. perniciosus was the most
widespread detected species, with a nationwide distribution. All studied species clustered together
with known samples from the Iberian Peninsula. Further monitoring studies of sandfly species
diversity, distribution, and seasonality are essential for surveillance and control of sandfly-borne
pathogens both nationally and globally
