Abstract

Microscopic examinations revealed that free-floating hard black bodies in larvae, pupae and adults of the Swaine jack-pine sawfly, Neodiprion swainei Midd., often contained polyhedra. A simple and rapid method for detecting the presence of the virus infection before gross symptoms appear is described.

Résumé

L’auteur rapporte la présence fréquente de polyèdres dans certains corps libres, noirs et durs trouvés dans les larves, pulpes et adultes de la tenthrède de Swaine (Neodiprion swainei Midd.). Il décrit une méthode simple et rapide de détection de cette virose avant que les symptômes évidents n’apparaissent.
