Abstract
Description of a newly discovered granulosis virus of the peach fruit moth Carposina niponensis and histopathological observation of the infected larva were reported in this paper.The oval capsules were approximately 480 nm long and 300 nm wide, while the virus rods were 265 nm long and 40 nm wide. Light microscopic observations of the infected larvae suggested that the fat body, tracheal matrix, Malpighian tubule, epidermis and midgut were the tissues susceptible to the virus. A cross-transmission test of the virus to larvae from four Tortricidae species, Adoxophyes sp., A. orana fasciata, Archippus breviplicanus, and Homona magnanima, was unsuccessful.
