Acta Entomologica Sinica 45 (2), 182-187
Abstract: A microsporidium (Mic- I) was isolated from Mimastra cyanura Hope caught from mulberry fields and vegetable plots in the suburban in Guangzhou. The spores were (3.35 ± 0.46) x (1.96 ± 0.17) µm in size, oval in shape. It had two types of nucleus, mono- and bi-nucleus, and 10 ~ 11 polar filament coils. The serum type of Mic-I was different from that of Nosema bombycis. It developed with two types of life cycles in larvae of the silkworm, Bombyx mori, had the developmental characteristics of the genus Vairimorpha and should be classified to Vairimorpha. It had very strong infectivity to Bombyx mori, and also had infectivity to Prodenia litura and Plutella xylostella.
