抄録

Larvae of the common cutworm Spodoptera litura infected with Japanese isolates of a microsporidium Nosema mesnili showed acute paralysis as early as 3 days postinoculation, and larval death followed within several days. Invasion of the parasites into the outer layer of larval ganglia occurred, and histopathological changes of the infected ganglia were evident. Small numbers of spores were observed in the cell body of the infected ganglia.
