ABSTRACT
Ultrastructure and development of a microsporidium isolated from a natural
Euproctis chrysorrhoea larval population in Western Bulgaria were
studied. Mature environmentally resistant spores of this microsporidium
possess typical diplokarya, 9-10 polar filament coils, smooth polaroplasts
and wavy exospores; we consider it to be a Nosema
species. Nosema sp. occurred in the fat body and silk glands of
E. chrysorrhoea and caused hypertrophy of the silk gland
cells. This species is not infective to closely related Lymantria
dispar. This Nosema isolate does not appear to be one of the
species previously described from E. chrysorrhoea.
