1. Variations in the population structure of Phlebotomine sandflies (Diptera: Psychodidae) in relation to the presence of potential dog hostsVladimir Ivović, 2025, izvirni znanstveni članek Opis: The seasonal and circadian population dynamics of Phlebotomine sandflies depend on many environmental factors, especially temperature and humidity. However, the factors that influence fluctuations in species composition are more uncertain. During the regular monitoring of arthropod vectors in the Slovenian coastal region, an interesting change in the population dynamics of these insects was observed, depending on the presence or absence of domestic dogs. To investigate the changes in species composition, we set traps for adult flies at two different locations (Medljan and Cetore) in the Coastal-Karst region (Izola, Slovenia). The collections were carried out in June and July 2017 and 2018. In total, 632 specimens of four species (Phlebotomus papatasi, P. neglectus, P. perniciosus and P. mascittii) were collected in the study area in both years. The females of all sandfly species were examined for the presence of Leishmania parasites in both years, but no Leishmania DNA was detected. The relocation of hunting dogs as potential reservoir hosts from Cetore to another location in early 2018 significantly changed the species composition of the sandflies. Two species, P. neglectus and P. perniciosus, were no longer present at this site. Changes in the species composition and population dynamics of phlebotomine sandflies are probably related to the presence or absence of the Leishmania reservoir host.

2. Monitoring of sandflies (Diptera: Psychodidae) and pathogen screening in Slovenia with habitat suitability modelingVladimir Ivović, Peter Glasnović, Sara Zupan, Tea Knapič, Tomi Trilar, Miša Korva, Nataša Knap, Urška Glinšek Biškup, Tatjana Avšič-Županc, Katja Adam, 2025, izvirni znanstveni članek Opis: Sandflies (Diptera: Psychodidae: Phlebotominae) are important vectors of pathogens, including Leishmania parasites and phleboviruses, but their distribution and seasonal activity in Slovenia have not been sufficiently studied. This study presents a comprehensive three-year (2020–2022) surveillance programme aimed at assessing the diversity of sandfly species, their distribution, seasonal dynamics and potential role as vectors of pathogens. A total of 1,240 sandflies were collected at 43 sampling sites across Slovenia, identifying Phlebotomus papatasi, P. neglectus, P. perniciosus and P. mascittii. The highest abundance and species diversity were observed in the Mediterranean and Karst regions. Seasonal activity peaked in July, with population fluctuations influenced by climatic conditions. Molecular analyses for Leishmania parasites and phleboviruses showed no positive results, indicating a low prevalence of pathogens in the sampled populations. Predictive habitat models indicate that environmental factors, particularly temperature and precipitation, play a decisive role in the spread of sandflies. While P. mascittii has the largest ecological range, its vector competence remains uncertain. The results provide important insights into the ecology of sandflies in Slovenia and emphasize the need for continuous surveillance in the context of climate change and emerging vector-borne disease risks.
