 Hollande and Vernier 



.Insects concerned: Malacosoma castrensis ; Malacosoma 

 neustria and Yanessa urticae . 



Hollande and Yernier (1920) found the "blood of 50 per 

 cent of the caterpillars of Malacosoma castrensis examined 

 to "be infected with a new organism which they named Cocco - 

 "bacillus insectorum var. malacosomae .

COCCOBAC I LLus LYMANTRIAE Picard and Blanc 

 (See also Bacillus lymantriae and Diplococcus lymantriae . ) 



Insect concerned: The gypsy moth, Lymantria dispar . 



Picard and Blanc (1913) discovered, in the caterpillars 

 of the gypsy moth, a fatal septicemia due to an organism 

 they named Coccobacillus lymantriae . It is difficult to 

 determine whether Bacillus (Bacterium) lymantriae , as 

 mentioned "by Paillot (1917, 1953)? is a synonym for 

 Coccobacillus lymantriae , "but it is probahle that they 

 are the same. The latter is not a spore -former, hence 

 the generic name Bacillus would not "be appropriate accord- 

 ing to present-day nomenclature.
