Sticky paper traps were used to demonstrate the presence of three sandfly species — Phlebotomus (Larroussius) perniciosus (Newstead 1911), Phlebotomus (Adlerius) mascittii (Grassi 1908) and Sergentomyia (Sergentomyia) minuta (Rondani 1843) — in canton Ticino (southern Switzerland) from 1981 to 1983. Some concentrations of P. perniciosus and S. minuta were noted in western Mendrisioto and minor Malcantone. Studies on the vertical distributions of sandflies showed S. minuta at 200-600 m, P. perniciosus at 300-600 m and P. mascittii at 400-700 m above sea level. When modified CDC light traps were used in certain biotopes, improved catches of P. perniciosus and P. mascittii were recorded. |
