Abstract
A method has been found to select the most virulent biotypes from a wild-type entomopathogenic virus by selection of desirable characteristics after serial passages through in vivo and in vitro systems. Using this method, a strain of Lymantria dispar NPV virus was isolated which had increased biological activity and increased speed of kill.
