Gyrococcus FLACC I D 1 FEX Glaser and Chapman 

 Insect concerned: The gypsy moth, Lymantria dispar . 



Glaser and Chapman (1912) isolated this organism from 

 caterpillars of the gypsy moth during their studies on 

 the cause and nature of the^wilt disease occurring in this 

 insect. These investigators originally "believed that this 

 organism was the cause of the wilt disease. It was later 

 discovered, however, that nearly all of the insects used 

 for experimentation had "become "accidentally infected" 

 with this "bacterium. In 1913 > Glaser and Chapman (see 

 Glaser, 1928) corrected their mistake and showed it to 

 "be caused "by a filterable virus. 



Gyrococcus flaccidifex w as described as a small (0.5- 

 O.85 microns), gram-negative, encapsulated organism, 

 resembling the pneumococcus more than any other form ex- 

 cept that it was motile, progressing in a "gyrating" 

 manner. It was from this latter characteristic that the 

 generic name was derived.
