Peroral Bioassay of Technical-Grade Preparations of the Douglas-Fir Tussock Moth Nucleopolyhedrosis Virus 'Baculovirus'

摘要

The potency of industrial preparations of viruses for control of injurious insects can be estimated reliably only be means of biological assay. The authors describe a simple, yet sensitive peroral procedure for technical-grade preparations of nucleopolyhedrosis virus. This procedure has been accepted by the Forest Service and the U.S. Environmental Protection Agency as the standard method for assaying industrial virus preparations for control of the Douglas-fir tussock moth.
