experimental conditions, he was able to kill "borers in one 

 and one -half days by infection with the "bacillus and its 

 spores. The organism has "been used quite effectively in 

 combating the corn "borer. (Husz, 1929? 1930). 



In some literature, (Chorine, 1929; Metalnikov and 

 Chorine 1929; Metalnikov and Chorine 1929a; Ellinger and 

 Chorine 1930a) Bacillus thuringiensis has "been referred 

 to as Bacterium thur Ingiens is . However, Ellinger and 

 Chorine (1930^) state "two strains of "bacteria that were 

 isolated from Ephestia kuhniella Zell. "by Metalnikov and 

 Chorine and utilized "by them against Pyrausta nubllalis 

 Hb. and were referred to as Bacterium thuringiensis numbers 

 1 and 2 . . . are identical with Bacillus thuringiensis 

 isolated "by Berliner and subsequently studied "by Husz." 

 Berliner named the organism correctly since it is a spore- 

 former. 



Chorine (1929) has given a complete description of 

 this organism.
