| Abstract: | A small kind of microsporidian was separated from silkworm, Bombyx mori (called as MG 4).The size of the spore was 2.72±0.12μm×1.98±0 22μm.Two types of nuclei,uninucleate and binucleate,were found.Polar filament was 6～9 coils.It had two different types of development cycles in silkworm bodies which is conformable to the features of Genus Vairimorpha .It parasitized mainly in tracheae of posterior midgut.It had a feeble oral infectivity to the silkworm.Transovarian transmission has not been found in silkworm after infecting. |
