A nuclear polyhedrosis virus was isolated from larvae of Anticarsia gemmatalis Hübner, collected from Chapec6, Santa Catarina in southern Brazil. Electron microscope studies revealed that the virus was multiply embedded with 1–11 virions/envelope. Average size of polyhedral bodies was 1.31 µm and virions, 195×25 nm. Infectivity studies revealed the virus was an effective pathogen at dosages as low as 17 PIB's/larva. Mortality occurred in 8–12 days at 26.7°C. In small plot field tests, the virus at 49 LE/ha significantly reduced populations of A. gemmatalis.
