BACTER 1 um PYRENE I _N_o . J_ Metalnikov et al. 

 Insect concerned: Corn "borer, Pyrausta nubilalis Hb. 



This organism was isolated "by Metalnikov, Ermolaev, 

 and Skohaltzyn (1930) from dead, "black larvae of corn 

 "borers that had "been received from the Pyrenees. Two 

 other organisms, Bacterium pyrene i No. 2 and Bacterium 

 pyrenei No . 3 were isolated from the same larvae. The 

 authors, pending complete analysis, gave the "bacteria 

 provisional names. All three strains were very pathogenic 

 for the corn "borer larvae and for other lepidoptera lar- 

 vae, which often died in 10 to 15 hours when infected "by 

 mouth with a virulent strain. The present author was 

 unahle to find subsequent reference to these organisms 

 other than Metalnikov (1930) and Sweetman (1936) who 

 refer only to a Bacterium pyrenei . 



The three strains are all spore -forming, so the generic 

 name should "be Bacillus .
