Oryctes Nudi virus against coconut rhinoceros beetle and possibility of its use against date palm dynastid beetles

The culture, release, establishment, and effect of Oryctes Nudi virus (OrNV) against the coconut palm rhinoceros beetle Oryctes rhinoceros L. is summarised. The occurrence of possible tolerance to OrNV in certain beetle populations in recent years is discussed. It is suggested that field-collected strains or variants of OrNV may be tested against the larvae and adults of date palm dynastid pests Oryctes elegans and Oryctes agamemnon for possible biological control.
