Abstract

Adults of nine species of thrips were collected from canola fields: Aeolothrips fasciatus (L.), Anaphothrips obscurus (Müller), Frankliniella occidentalis (Perg.), Frankliniella tritici (Fitch), Limothrips denticornis Haliday, Odontothrips loti (Haliday), Thrips nr. fuscipennis Haliday, Thrips tabaci Lindeman, and Thrips vulgatissimus Haliday. Of these, F. tritici was the most abundant in the collections and appears to have the greatest potential to be a significant canola pest, followed by T. tabaci and T. vulgatissimus.

Résumé

Les adultes de neuf espèces de thrips ont été prélevés de champs de colza canola : Aeolothrips fasciatus (L.), Anaphothrips obscurus (Müller), Frankliniella occidentalis (Perg.), Frankliniella tritici (Fitch), Limothrips denticornis Haliday, Odontothrips loti (Haliday), Thrips nr. fuscipennis Haliday, Thrips tabaci Lindeman et Thrips vulgatissimus Haliday. Parmi ces espèces, F. tritici est le plus abondant dans les collections et semble le plus susceptible d’être un ravageur important du canola, suivi par T. tabaci et T. vulgatissimus.
