Bengtson (1922) isolated an anaerohic spore -forming 

 organism from the larvae of Luc ilia caesar which caused 

 limberneck in chickens. She did not give a name to the 

 organism hut in Bergey 1 s Manual (3d ed. , 1930) the organ- 

 ism is referred to as Clostridium luciliae Bengtson. 

 However, in the 5th edition (1939, P- 755), the organism 

 is called Clostridium hotulinum Type C. Bengtson. 



Gunderson (1935) reported finding Clostridium hotulinum 

 type C in "both larvae and cocoons of the water-heetle , 

 Enochrus hamiltoni , and attributed an epizootic among 

 sandpipers to he due to the presence of this organism in 

 the larvae, the sandpiper feeding upon them.

Insect concerned: The hee moth, Galleria mellonella . 



Metalnikov (1920) made a number of experiments to deter- 

 mine the immunity of the larvae of the hee moth against 

 various classes of microorganisms. He found the larvae 

 to he completely immune to infection with Clostridium 

 tetani .

 Insect concerned: The rose-leaf "beetle, Potosia cuprea . 



Werner (1926) isolated a "bacillus from the digestive 

 tract of the larva of Potosia cuprea which fermented cellu- 

 lose. He called the organism Bacillus cellulosam fermen - 

 tans and it was designated as such in the 4th edition of 

 Bergey 1 s Manual. However in the 5th edition, 1939 (see p. 

 785 ) , the name was changed to Clostridium werneri . 



Werner was unahle to decide whether the larva uses the 

 products of fermentation of cellulose directly for meta-
