Abstract
WITH reference to the communication by Dr. G. H. Bergold and Dr. W. E. Ripper on the polyhedral virus of Heliothis armigera 1, it has evidently escaped their notice that the virus of this nuclear polyhedral disease has already been isolated and characterized on the electron microscope. Furthermore, experiments in the use of this virus in the control of the American cotton bollworm in Uganda are now actively in progress in collaboration with Mr. T. H. Coaker, of the Empire Cotton Growing Corporation2.
