 of San Dimas, Glendale, San Fernando and Pacoima, Los Angeles 

 County, where it has been claimed that the black scale {Saissctia 

 olece) has been controlled by artificial inoculation with a fungous 

 parasite, and find no evidence, either in treated or untreated 

 groves, that a fungus of any kind has entered into the control 

 of this pest in Los Angeles County. 



No difference between the treated and untreated trees was 

 noted.
