Comparative Studies on Two Strains of Nuclear Polyhedrosis Viruses of Philosamia Cynthia ricini (Attacus ricini)
Abstract: In this paper the morphological characteristics and biochemical properties of two strains of Attacus ricini nuclear polyhedrosis virus isolated from different sources were described. One strain of Attacus ricini was fed with leaves of Coriatia Sinica for many years (the vernacular name: Coriatia sinica silkworm), and virus was obtained from larvae and pupae. The other strain of Attacus ricini was fed with leaves and virus was obtained from larvae of Attacus ricini. Morphology of polyhedra was slightly diffe...
