A Polyhedral Virus Disease of a Pasture Caterpillar, Pterolocera Amplicornis Walker (Anthelidae)

Abstract

A new virus of the genus Borrelfna, causing a polyhedral disease in larvae of the anthelid moth Pterolocera amplicomis, is described. The polyhedral bodies are small and unusually resistant to alkaline solution. Electron micrographs reveal the presence of rods, spheres, and rods projecting from spheres in alkali-digested polyhedra. The relations between these bodies are not clear.
