The history of the associations between insects and 

 Serratia marcescens is very interesting. In stating it 

 "briefly we quote from DeBach and McOmie (1939): 



"Masera (1936a) in a comprehensive treatment 

 of the subject states that as early as 1817 Rozier 

 noticed a red coloration forming in the dead todies 

 of silkworms. This was again noticed by Pollini 

 and Vasco in 1819, Re and Ascolese in 1837, etc. 

 However, the credit for the actual isolation in 

 1886 of Bacillus prodigiosus from a silkworm larvae 

 is due to Perroncito. Bandelli ahout the same time 

 isolated Bacillus prodigiosus from the exterior of 

 silkworms ( Bombyx mori ) and later stated that the 

 red pigment did not appear until after the death of 

 the larvae. 



"Metalnikov (1930) isolated a red-pigment former 

 like Bacillus prodigiosus from the larvae of the 

 gypsy moth, Lymantria dispar (L. ) which was very 

 virulent. [Earlier (1920) this worker found the bee 

 moth, Galleria mellonella , to offer no resistance to 

 this "bacterium, dying from very small doses.]
