Bac 1 LLU S CUBON I ANUS Cuboni and Garhini 



Insect concerned: The silkworm, Bombyx mori. 



Cuboni and Garhini (189O) thought this "bacillus was the 

 cause of flacherie in silkworms. However, Paillot (1928) 

 points out that it is pdssible to artificially infect 

 .silkworms with the "bacillus and .that the symptoms charac- 

 teristic of flacherie are not present.

Bac 1 llus cuenot I Mercier 



Insect concerned: The oriental roach, Periplaneta orien - 

 talis . 



Mercier (1907) studied in considerable detail the 

 ""bacteroids" found in the adipose tissues of the cockroach. 

 He isolated a spore -forming rod which he thought was an 

 intracellular microorganism and named it Bacillus cuenoti . 

 More recent work, however, has shown .that this "bacillus 

 is prohahly a contaminant and not identical with the 

 intracellular microorganism found in the fat "body of the 

 cockroach. (See Hertig, 1921; Glaser, 1930, and Gier 

 (quoted "by Steinhaus, 19^-0)).
