Nuclear Polyhedrosis Virus from Ectropis obliqua hypulina Wehrli in its Host Larvae
Abstract: Effect of temperature on the growth dynamics of the nuclear polyhedrosis virus form Ectropis obliqua hypulina (EoNPV) in its host larvae was studied through polyhedra counting, counter immuno-electrophoresis, single immunodiffusion and rocket immuno-electrophoresis tests. The propagation of the virus in the host larvae fed with the NPV at the concentration of 2.6 10~7PIB/ml and reared at 26℃ was normal. The polyhedra titer or its relative equivalences increased positively with the time after inoculation and...
