In order to evaluate the potential application of microsporidia as a microbial control agent against lepidopteran insect pests, microsporidian infection in a field population of the common cutworm, Spodoptera litura (Fabricius), was surveyed in vegetable crop fields in Can Tho City, Vietnam, in March 2007. The infection rate of microsporidia was 46.7% (99/212 individuals) in adult S. litura, and 16 samples of infected adults were used to characterize the microsporidia at the molecular level. Analysis of the small subunit ribosomal RNA (SSU rRNA) sequences indicated that microsporidian strains isolated from S. litura were closely related to Nosema bombycis from the silkworm, Bombyx mori (Linnaeus); however, phylogenetic analysis based on genome profiling produced a different result from the SSU rRNA sequences. Temperature gradient gel electrophoresis profiles of 12 microsporidian strains from S. litura were closely related to N. bombycis strains, while the profiles of three microsporidian strains formed a different cluster. The Vietnamese strains did not form a single group, but were classified into at least three groups. These results suggested that the microsporidia isolated from S. litura in the Mekong Delta, Vietnam, are genetically diverse.

“…The genus Vairimorpha was established by Pilley (1976) after Thelohania diazoma (Kramer, 1965), which has a octosporoblastic sequence resulting in uninucleate spores, was shown to be the same species as Nosema necatrix, which has the normal disporoblastic sequence typical of Nosema (Fowler and Reeves, 1974). The type description for Nosema does not include dimorphic developmental sequences or octosporoblastic sporogony.…”
