White (190^) cultured on special media the ahove organ- 

 ism which he and others had found to he the cause of Amer- 

 ican foulhrood in hees. Pending more definite information 

 in regard to the "bacterium, he temporarily called it 

 Bacillus "X", later (1905, 1906) naming it Bacillus larvae . 

 He states that Bacillus hrandenhurgiens is and Bacillus 

 hurri are other names that have heen used for the same 

 species. See White (1920) for a complete description of 

 the organism.

Bacillus lasiocampa Brown 



Insect concerned: The tent caterpillar moth, Malacasoma 

 americana . 



Brown (1927) found Bacillus lasiocampa throughout the 

 entire female genital system (ovaries and egg tubes) of 

 the tent caterpillar moth and he readily cultivated it 

 from the dissected organs. The females infected with this 

 spore -forming hacillus seemed unahle to deposit their eggs, 

 though the organism was not found in the eggs. However, 

 Alcaligines stevensae (which see) was present. A complete 

 description of Bacillus lasiocampa is given "by Brown.

Bac I LLUS LATH YR I Manns and TaulSenhaus 

 ( Erwinia lathyri ) 



Insect concerned: Aphis rumicis . 



Needham (193 7-) isolated from diseased Aphis rumicis an 

 organism culturally resembling Bacillus lathyri . The same 

 "bacillus was not found in uninfected aphids.
