Abstract

Predispersal seed predation of Cirsium arvense (L.) Scop. (Asteraceae) by Orellia ruficauda (Fabr.) (Diptera: Tephritidae) occurs in about 20–85% of the seed heads and the proportion of damaged seeds per attacked head averages 20–80% depending on geographical location and sampling date. Microscopic studies of damaged seeds were performed. Although the impact of this seed predator is not severe, it may be an important factor in the population regulation of the weed.

Résumé

La prédation des graines de Cirsium arvense (L.) Scop. (Asteraceae) avant leur dispersion par Orellia ruficauda (Fabr.) (Diptera : Tephritidae) est observée sur environ 20 à 85% des inflorescences et implique, selon la région géographique et la date d'échantillonnage, de 20 à 80% des graines des inflorescences attaquées. Les graines endommagées ont été examinées en détail. Bien que l'impact causé par ce prédateur ne soit pas sévère, il est possible qu'il soit un facteur important dans le contrôle du niveau de population de cette mauvaise herbe.
