Abstract
Three new pathogenic bacteria were isolated from milky diseased larvae of Popillia japonica NEWMANN, Anomala rufocuprea MOTSCHULSKY and Anomala daiminana HAROLD (Coleoptera; Scarabaeidae) reared in the laboratory after field collection from golf courses in Sapporo in 1993. the morphological features regarding bacterial spores, infectivity host range and plasmid DNA profiles in these isolates showed different types of strains of Bacillus popilliae. Milky diseased larvae of P. japonica and other beetles have not yet been reported in Japan. This report is therefore the first of its kind in Japan.
