Abstract
In view of the background of information on Bacillus popilliae Dutky (Beard, 1945) and the reported success of this bacterium in reducing populations of Popillia japonica Newm. (White and McCabe, 1950) and in view of the discovery of a similar bacterium attacking Odontria grubs in New Zealand (Dumbleton, 1945), a survey of microparasites and their possible pathogenicity in scarabaeid larvae was undertaken in Australia as a project supported by a Fulbright award.
