The development of Tipula iridescent virus in the crane fly, Tipula paludosa Meig., and the wax moth, Galleria mellonella L.

Abstract

Patches of material rich in desoxyribonucleic acid form in the cytoplasm of cells of the silk gland, fat body, epidermis, tracheal epithelium, and muscles of the crane fly, Tipula paludosa Meig., and the wax moth, Galleria mellonella L., infected with Tipula iridescent virus. The development of virus particles appears to be associated with strands of dense material in the cytoplasm of susceptible cells. Each particle consists of a central core surrounded by a membrane. After their formation many of the particles appear to become surrounded by protein.
