The preservation of infective spores of nosema necatrix protozoa microsporida in spodoptera exempta lepidoptera noctuidae by lyophilization


, : The preservation of infective spores of nosema necatrix protozoa microsporida in spodoptera exempta lepidoptera noctuidae by lyophilization. Journal of Invertebrate Pathology 27(3): 349-350

Cadavers of S. exempta infected with N. necatrix were lyophilized. The lyophilized material was tested against a standard spore preparation 1 day after lyophilization and retested 2 yr later. There was some loss of spore viability. The feasibility of using dose-mortality experiments to estimate loss in viability is discussed.
