Sand fly sample collection

Sand fly data collection involved longitudinal entomological surveys conducted from April to November 2023.  

This included the use of CDC light traps for two nights per month across 30 sampling locations. Of these, 14 were situated in the Metropolitan Region of Lisbon (Lx), while the remaining 16 were in the Algarve region (AL).  

Sampling sites included various animal habitats such as hen houses, stables, and kennels. Additionally, data loggers were deployed at each location to monitor temperature and humidity levels every two hours.

The insects are captured at night, and they will be collected to later be analysed in the laboratory.

Sand fly specimens
Sand fly specimens

Specimens were captured in a single trap, with a ‘red’ female in the middle.

Red female sand fly

This female will be used, following morphological identification, for the extraction of nucleic acids and detection of Leishmania, and Phlebovirus, and also for identifying the food source.
