Tateiwa had isolated from silkworms with "flacherie" and 

 had called Bacterium prodigiosus (prohahly prodigiosum ) 

 produced 20-30 per cent mortality in corn "borers infected 

 "by mouth. 



The writer (Steinhaus, 1939) attempted to establish 

 Serratia marcescens as part of the "bacterial flora in the 

 gut of the milkweed hug, Oncopeltus fasciatus , hy experi- 

 mental feedings hut was unsuccessful. Later (19^1), he 

 used this hacterium to demonstrate that the tick, Derma - 

 centor andersoni , could acquire hacteria from the skins 

 of experimental animals and pass these "bacteria from 

 larvae to adults. 



The possible germicidal action of the gastrointestinal 

 secretions of the yellow-fever mosquito, Aedes aegypti , 

 on Serratia marcescens was found to he negative hy St. John, 

 Simmons, and Reynolds (1930). It was further found that 

 this "bacterium, as well as others, survived for at least 

 2k hours in the gut of the mosquito hut that it could not 

 he demonstrated after an interval of seven or more days.
