Abstract

The spruce budworm, Choristoneura fumiferana (Clemens), is susceptible to two types of granulosis virus. One is characterized by the formation of mostly small ellipsoidal inclusion bodies, the second by the formation of large cubic inclusion bodies. Different shapes and sizes of inclusion bodies were formed when these viruses multiplied in the same tissues, some resembling the ellipsoids, others the cubes.

Résumé

La Tordeuse des bourgeons de l’Epinette, Choristoneura fumiferana (Clemens) est vulnérable à deux types de virus de la granulose. Le premier type est caractérisé par la formation d’une majorité de petires inclusions ellipsoïdes, tandis que l’autre se distingue par la formation de grosses inclusions cubiques. Lorsque ces deux virus se multiplient des les mêmes tissus, on observe différentes formes et grosseurs d’inclusions ressemblant soit à des ellipsoïdes, soit à des cubes.
