Insects and ticks concerned: The honey "bee, Apis nielli - 

 fera; the bedbug, Cimex lectularius ; Stomoxys calci trans ; 

 Rhodnius prolixus ; and the ticks , Argas persicus and 

 Qrnithodoros moubata . 



In attempting to determine the cause of "blackbrood" 

 in "bees, Serbinow (1912) isolated Bacillus mesentericus , 

 which is widely distributed in soil and dust. 



Duncan (1926) found "B. mesentericus " and "B. vulgatus ,t1 



-'-According to Bergey's Manual, 5th edition, pp. 6^7-6^9, 

 Bacillus vulgatus is considered synonymous with Bacillus 

 mesentericus .

 contents of Argas persicus , Qrnithodoros moubata , Stomoxys

Bacillus millii Howard 



Insect concerned: The honey "bee, Apis mellifera . 



Howard (1900) reported a new "bee disease and called it 

 "New York "bee disease" or ""black "brood. " He gave as its 

 cause an organism, which he called Bacillus millii . 



White (1906) is of the opinion that "New York bee 

 disease" is really genuine European foulbrood, caused by 

 Bacillus alyei. He states : "In our investigations of
