Bacter 1 um CANADEN s 1 s Chorine 



Insects concerned: The corn "borer, Pyrausta nubilalis ; 

 Galleria mellonella ; Ephestia kiihniella . 



Chorine (1929) isolated this organism from diseased 

 Canadian corn "borer larvae and found it to "be very patho- 

 genic to the larvae of the above-listed insects, all being 

 easily infected "by mouth. In Its general characteristics, 

 it resembles Bacillus megatherium and Bacillus thuringi en - 

 sis . A complete description of the organism has "been 

 given "by Chorine (1929). 



Since the organism is a spore-former, it would seem 

 that the generic name Bacillus is preferable to that of 

 Bacterium .
