摘要：

DNA synthesis was studied autoradiographically in larval tissues of normal Erannis vancouverensis, and in normal nuclear polyhedrosis-virus-infected tissues of Lambdina fiscellaria lugubrosa and L. f. somniaria. The results confirm previous histochemical indications that DNA synthesis increases up to a point just prior to polyhedron formation and then decreases. The synthesis of DNA ceases in nuclei containing mature polyhedra. DNA synthesis was higher in normal fourth-instar L. f. lugubrosa and L. f. somniaria than in normal fifth-instar E. vancouverensis. DNA synthesis ceased in prepupal midgut but was resumed in the pupal midgut. Cells which are prime targets of polyhedrosis-virus infection actively synthesized DNA during the prepupal and pupal stages of E. vancouverensis. © 1968.
