A new iridescent virus obtained from two larvae of the rice stem borer, Chilo suppressalis WALKER, was described and named Chilo iridescent virus (CIV). It seemed to be the first finding of this kind of virus in a lepidopterous insect collected in nature. The virus particle appeared hexagonal in outline and the average diameter was about 160 mμ. Although it showed morphological similarity to TIV, little serological relationship between CIV and TIV was so far observed. The lavae of the rice stem borer were readily infected with CIV by intrahemocoelic inoculation or by feeding.
