The symptoms conformed to those reported from South East Asia and the South Pacific Islands. The disease was diagnosed and confirmed by visual symptoms of midgut, smear of midgut contents, immuno-osmophoresis, bioassay in grubs and beetles and electron microscopy of midgut sections of the beetle. The smear test and immuno-osmophoresis were found to be ideal diagnostic methods for routine screening. The bacilliform baculovirus particles measured 215-260x77-108 nm.enbaculovirus diseaseoryctes rhinocerosArticle
