Bac l LLus pyocyaneus Gessard 



Insects concerned: Schistocerca gregaria ; the "bee moth, 

 Galleria mellonella ; the silkworm, Bombyx mori ; the house 

 fly, Musca domes tica ; and Stomoxys calci trans . 



MetalnikOv (1920) in a series of experiments to deter- 

 mine the immunity of the "bee moth against certain classes 

 of microorganisms, found the "bee moth susceptihle to small 

 doses of Bacillus pyocyaneus . Couvreur and Chahovitch 

 (1921) found that the "blood and digestive juices of the 

 larvae and pupae of Bombyx mori destroyed the organism. 

 Sawamura (I906) lists this organism as "being artificially 

 pathogenic to the silkworm. 



Duncan (1926) isolated it from the gut contents of one 

 lot of Stomoxys calcitrans . 



During an epidemic which occurred in the laboratory 

 rearing of Schistocerca gregaria , Lepesme (1937) found 

 Bacillus pyocyaneus present in the "body fluid. Experi- 

 mentally, it caused death in one to two days. He (1938) 

 also found it to be a secondary invader to the infestation 

 of the fungus, Aspergillus flavus, in this insect. 



Bacot (1911) found that the pupae and imagines of Musca 

 domes tica "bred from larvae infected with Bacillus pyo - 

 cyaneus remain infected with the "bacillus. 



Pseudomonas aeruginosa is the accepted name for Bacillus 

 pyocyaneus . (See Bergey's Manual, 5th ed. , p. 126. "5
