Thirteen isolates of granulosis virus from (= ) and two from were compared by restriction enzyme analysis. All the isolates gave very similar fragment profiles with I, I and I. but at least 11 of them could be distinguished using RI, I and dIII. Similarities and differences between profiles suggested that the isolates could be placed in three subtypes. This subtyping correlated closely with the geographical origin of the isolates, which came from Europe, North America, Asia and Australasia. All the isolates were highly infectious for with median lethal dose values for third instar larvae ranging from 10 to 10. Only two of four isolates of one subtype had significant infectivity for third instar ; thus, this broader host range did not correlate with grouping by restriction enzyme analysis.
