The First Isolation of Microsporidia from Dragonflies in Japan.
The First Isolation of Microsporidia from Dragonflies Abstract: Entomopathogenic microsporidia are pathogens of various arthropods and therefore cause disease in important host species ranging from agricultural pests to beneficial insects. Here, we investigated three genera of en tomopathogenic microsporidia from dragonflies ; these were isolated in Kanagawa, Japan, in 2014. In total, the infec tion rate was 0.85% ( 16 of the 1,886 surveyed dragonfly adults ) . Four strains of microsporidia selected from infected Orthetrum albistylum speciosum ( Uhler )( Odonata: Libellulidae ) adults were measured for spore size and analyzed at the molecular level. According to spore size, the four strains were roughly divided into two groups. Analysis of small-subunit ribosomal RNA sequences indicated that the microsporidia strains belonged to the Trachipleistophora , Vavraia , and Paranosema clusters. Microsporidia species that are closely related to the strains isolated in this study have previ ously been reported to infect insects other than dragonflies. Therefore, we suggest the possibility that the microsporid ian strains we isolated in O. albistylum speciosum may also infect other insect species.
期刊介绍:
The Japanese Journal of Applied Entomology and Zoology has the abbreviated Japanese name, "ODOKON", and publishes papers on fundamental and applied research, reviews of research and book reviews in order to promote and spread information from the extensive fields related to applied entomology and zoology. This journal publishes contributions of research on entomology and zoology concerning agriculture, medicine, ecology, etc., and bears a leading role to publish pioneering works in these fields. The contributors belong to universities, independent administrative agencies, public institutions, private enterprises, etc., and the contents of papers have a diverse and varied range.
