Bacterium prodeniae Metalnikov and Metalnikov 



Insect concerned: Prodenia li tiara . 



Metalnikov and Metalnikov (1932) isolated this organ- 

 ism from larvae of Prodenia li tiara while studying diseases 

 of this insect and those of Gelechia gossypiella .

Insect concerned: Corn "borer, P yrausta nubilalis Hb. 



Metalnikov and Chorine (1928) isolated seven pathogenic 

 "bacteria from diseased corn "borers which had heen collect- 

 ed from mugwort plants around Paris. The authors con- 

 sidered them to "be of little importance "because they were 

 not ahle to infect corn "borers "by mouth, so the organisms 

 were merely numbered. No. 1 was found to he very viru- 

 lent for corn "borer larvae when injected. The workers 

 have "briefly described the "biological characteristics of 

 each of these in tahular form.
