Bacillus lathyri was first isolated from, diseased sweet 

 peas. According to Bergey's Manual (5th ed. , p. U13) it 

 is now called Erwinia lathyri .

Insect concerned: The Japanese beetle, Popillia japcnica . 



Dutky (19^0) found Bacillus lentimorbus to be the cause 

 of "type B" ra.il.ky disease of Japanese beetle larvae, The 

 "type A" disease was caused by an organism he named 

 Bacillus popilliae . Dutky describes both organisms and 

 the diseases they cause. He was unable to artificially 

 culture Bacillus lentimorbus .

BAC I LLUS LEFT 1 NOTARSE White 



Insect concerned: The Colorado potato beetle, Leptinotarsa 

 decernlineata . 



White (I928) found this organism, to be pathogenic for 

 the larvae of Leptinotarsa decernlineata . The disease is 

 characterized by a septicemia and the bacillus may be 

 found in the larval blood. The infected larvae are found 

 clinging to the potato plant; the dead ones are usually 

 on the ground. In a later report, White (1935) stated 

 that this organism was similar to Bacillus sphingidis and 

 Bacillus noctuarum .
