BAC 1 LLUS SPH 1NG I D I S White 

 (See also Bacillus noctuarum White. ) 



Insects concerned: The tomato-worm, Protoparce ( Phlego - 

 thontius ) quincniemaculata ; the tohacco-worm, Protoparce 

 ( Phlegothontius ) sexta ; the catalpa moth caterpillar, 

 Ceratomia catalpae ; and the silkworm, Bombyx mori . (See 

 also those insects listed under Bacillus noctuarum . ) 



As indicated on page 605 of the 5th edition of Bergey's 

 Manual, Bacillus sphingidis Is very similar, if not identi- 

 cal, to Bacillus noctuarum . These two organisms seem to 

 have enough characteristics in common to he considered the 

 same species. Bacillus sphingidis has also "been known "by 

 the names: Escherichia sphingidis (Bergey's Manual, 3<1 ed. , 

 1930, p. 327) and Proteus sphingidis (Bergey's Manual, 

 4th ed. , 1934, p. 36*6y 



Bacillus sphingidis is a Gram-negative, non- spore -forming, 

 short rod. Inasmuch as the genus Bacillus is reserved for 

 spore -forming rods only, it can he seen that Bacillus 

 sphingidis does not hear the proper generic name. 



According to White (1923) caterpillars, feeding on 

 tohacco and tomato leaves, have "been found to develop a 

 disease caused "by Bacillus sphingidis . This "bacterium is 

 also pathogenic for the larvae of Ceratomia catalpae and 

 the silkworm, Bombyx mori .
