Restriction endonuclease analysis to distinguish two closely related nuclear polyhedrosis viruses: Autographa californica MNPV and Trichoplusia ni MNPV.

Restriction endonuclease fragment patterns of the deoxyribonucleic acid genomes of Autographa californica nuclear polyhedrosis virus (multiply embedded type) and Trichoplusia ni nuclear polyhedrosis virus (multiply embedded type) demonstrate that the two viruses are distinct but closely related variants.
