The nucleic acids of viruses infecting Heliothis armigera

Abstract The nucleic acids of three viruses infecting Heliothis armigera have been studied. A nuclear polyhedrosis virus and granulosis virus contained double-stranded DNA. A cytoplasmic polyhedrosis virus contained double-stranded RNA, and polyacrylamide gel electrophoresis showed that the genome consisted of 10 discrete double-stranded RNA components.
