Insect concerned: The white cabbage butterfly, Pieris 

 brassicae . 



Paillot (1919) isolated Bacillus proteidis from larvae 

 of diseased cabbage butterflies. From, the same source, 

 he isolated eight other bacteria. (See Bacillus pieris 

 fluorescens . )

B&C I LLU S PSEUDOXEROS I S NogUChi 

 Tick concerned: The woqd tick, Dermacentor andersoni . 



Noguchi (I926) isolated Bacillus pseudoxerosis from the 

 wood tick. It was one of three microorganisms he found in 

 this arthropod. These organisms morphologically resembled 

 the rickettsia causing spotted fever. However, they were 

 found to be non-pathogenic for laboratory animals and 

 immunologically they were not related to the spotted fever 

 rickettsia. 



Bacillus pseudoxerosis is a non-motile, slender, pleo- 

 morphic bacillus. It is apparently non-spore -forming, 

 hence the generic name Bacillus is not acceptable accord- 

 ing to rules of nomenclature.

BAC I LLUS PUNCTATUS 



Insect concerned: Locus ta migratoria . 



In experimental infection of Locus ta migratoria using 

 a mixture of Bacillus fluorescens liquefaciens , Bacillus 

 punctatus , and Coccobacillus acridiorum , Shul'gina and 

 Kalinicker (1927) found the mixture gave a low mortality.
