Abstract

The introduced parasite Lophyroplectus luteator Thunberg has spread 305 km in an easterly direction in the 13 years since its release and has dispersed faster in southern Ontario than its host, Neodiprion sertifer (Geoffroy). The prevailing westerly winds were probably an important factor. The limited dispersal from a second liberation is discussed.

Résumé

Le parasite introduit Lophyroplectus luteator Thunberg s’est répandu sur 305 km en direction est depuis qu’on l’a relâché il y a 13 ans. Il s’est dispersé plus rapidement que son hôte, Neodiprion sertifer (Geoffroy). Les vents d’ouest prédominants ont probablement été un facteur important. L’auteur expose son point de vue sur la dispersion limitée à partir d’un second ensemencement du parasite.
