Laboratory disinfectants as preservatives for Helicoverpa armigera nucleopolyhedrovirus.

摘要

The efficacy of acetone, dettol, ethyl acetate, ethyl alcohol, phenyl and methanol against bacterial contaminants in H. armigera nuclear polyhedrosis virus (NPV) was evaluated. All the preservatives reduced bacterial contamination and the associated bad odour problem during storage. NPV samples stored with preservatives resulted in 90% mortality of H. armigera in laboratory bio-assays after 2 months of storage. Samples stored in acetone and ethyl alcohol resulted in 73.3 and 70.0% mortality, respectively, after 10 months of storage. The cost of different preservatives ranged from 3.0-12.5 rupees ha-1.
