Abstract

A previously undescribed entomopoxvirus was isolated from larvae of Choristoneura conflictana Wlk. Samples of larvae taken from several points in Ontario indicated that the virus was widespread in the Province.

The morphology of the virus is described. The inclusion bodies are larger than those of another entomopoxvirus originally isolated from Choristoneura biennis Free. and propogated in Choristoneura fumiferana (Clem.). The virions are of the same order of size for both viruses. Microspindles are associated with these viruses and some of the spindles are occluded along with the virions within the oval inclusion bodies. The C. conflictana entomopoxvirus is also infectious to C. fumiferana.

Résumé

Les auteurs ont isolé de la larve de Choristoneura conflictana Wlk. un virus à vérole d’insectes non encore décrit. A la suite d’échantillonnages de larves en plusieurs localités de l’Ontario, ce virus aurait une large distribution. Suit une description du virus : les inclusions cytoplasmiques sont plus grosses que celles d’un autre virus à vérole isolé de Choristoneura biennis Free. et propagé dans Choristoneura fumiferana (Clem.). La grosseur des virions est du même ordre de grandeur chez les deux. Des enclaves microfusiformes existent dans ce virus. Certaines parmi celles-ci se trouvent avec les virions dans les inclusions ovales. Ce nouveau virus peut aussi infecter C. fumiferana.
