Abstract

A 5-year study of the black flies of east-central Saskatchewan revealed 21 species, including Simulium incognitum sp.nov. Chromosomal and ecological evidence for reproductive isolation is presented for this new species, formerly known as S. venustum Say CC4, and S. venustum Say CC. All 21 species in the study are associated with productive streams and rivers. As many as nine of these species might comprise the pest assemblage harassing livestock. The major pest, S. luggeri Nicholson and Mickel, is cytologically distinct from populations in the eastern United States on the basis of a two-step, Y-linked inversion in the IIS chromosomal arm. Simulium luggeri is the only livestock pest that breeds almost solely in large streams and rivers. The other eight probable pests breed entirely or partly in streams less than 10 m wide, often below beaver dams, suggesting that management efforts should specifically target these sites.

Résumé

Une étude des mouches noires pour 5 années dans la région l’est-centrale de Saskatchewan a révélé 21 espèce, y compris Simulium incognitum sp.nov. Nous présentons évidences chromatiques et écologiques qui indique l’isolement reproductive pour cette nouvelle espèce, autrefois connu comme S. venustum Say CC4, et S. venustum Say CC. Toutes les espèces ont trouvé dans cette étude habitant dans les courants et fleuves productifs. C’est possible que neuf espèces sont les nuisables qui harcellent le bétail. La cytologie du nuisable principale, S. luggeri Nicholson and Mickel, est different des populations dans l’est des États-Unis dans un deux-étape, inversion Y-enchaîne dans la bras chromatique IIS. Simulium luggeri est la seul nuisable du bétail qui élève dans les grands courants et fleuves. Les huit autres nuisables élèvent exclusivement ou en partie dans les courants moins de 10 m large, souvent en bas des digues du castor. Cet information indique que ces emplacements devront les cibles d’une stratégie de lutte.
