In Italy, some cases of massive attack by blackflies (reptans group) to both cattle and humans occurred in subalpine and alpine valleys of Lombardia, Trentino, and Veneto (ZANIN & RIVOSECCHI, 1975; RIVOSECCHI & COLUZZI,1962), resulting in several animal deaths. In Marches (Cen-tral Italy), Simulium intermedium attacked humans (RIVOSECCHI, 1997). In the present study, we provide an initial evaluation of the possibilities of blackfly attacks in the Alessandria Province (eastern part of the
more » ... part of the Piedmont region, NW Italy), where the Simuliidae fauna is still mostly unknown. This evaluation is based on the results of investigating a wide selection of streams of different ranks in the Scrivia, Borbera, Lemme, Bormida and Belbo catchments for the presence of lar-vae, pupae, and adults.
