Bac I LLus G I bson I Chorine 



(See Cocco"bacillus gibsoni ) 



Insect concerned: The corn "borer, Pyrausta nubilalis . 



According to Paillot (1933) Chorine isolated this or- 

 ganism from the corn borer in 1929 and found it to "be 

 pathogenic. This is apparently the same organism that 

 Chorine isolated in 1929 and called Cocco"bacillus gibsoni 

 (which see). Paillot says the organism is a spore former 

 "but in Chorine's (1929a, b) original articles, he states 

 that the organism is non-sporulated, hence the generic 

 name Bacillus would not "be applicable.

Bac i llus g i gas G-oot 



Insect concerned: Adoretus compressus . 



According to G-oot (1915) Adoretus compressus is attacked 

 "both in the larval and adult stages "by Bacillus gigas . He 

 found that it destroyed large numbers of the larvae in the 

 insectary.

Bag 1 llus gortynae Paillot 



Insects concerned: Gortyna ochracea ; the gypsy moth, 

 Lymantria dispar , 



Paillot (1913) discovered this "bacillus in the cater- 

 pillars of Gortyna ochracea. It had "been the cause of an 

 epidemic among them. The insects lost all use of their 

 legs with the exception of the first pair, and the poster- 

 ior part of the "body seemed to have lost all sensation. 

 Microscopic examination of the "blood showed a great many
