The Bulletin. 17 



Quaintance lists 18 species of these whieli have been bred from the San 

 Jose Scale. He states, however, that even at the highest rate of para- 

 sitism ever yet recorded "the control of the scale by these agencies cannot 

 be depended npon." 



In Florida a fungous disease has been found to prey upon the scale 

 to a considerable extent, but attempts to introduce this into other sections 

 have not met with much success. 



Some years ago the United States Department of Agriculture at Wash- 

 ington introduced from China a species of Lady Beetle closely related to 

 our "Twice-stabbed" species, and indeed one cannot easily tell one from 

 the other. This also feeds upon the San Jose Scale, but thus far has not 

 shown itself capable of holding it in practical control. We must still 

 rely upon the spray pump if we wish to keep this pest in subjection. 



History. Where Did it Come From? — There has been much discussion 

 in reports and bulletins as to the probable original home of the San Jose 

 Scale. From present evidence, however, it seems certain that it origi- 

 nated in northern China, and that from there it was introduced into 

 California about 1870. The insect remained unknown to science, how- 

 ever, until 1880, when it was first described. At that time it was de- 

 structive in orchards in the Santa Clara valley near the city of San Jose 

 (pronounced San Ho-zay), in California, and it is from* that city that it 

 has received its name. 



The insect was not discovered in the eastern United States until 

 August, 1893. xVt that time it was found in Charlottesville, Va. It was 

 soon found that the infested trees were purchased from nurseries which 

 had been introducing stock from California. Then fruit-growers and 

 entomologists began to inspect orchards especially for this pest, and in 

 1897, five years after its discovery in Virginia, it was known to exist in 

 twenty States east of the Mississippi Kiver. 



It seems likely that it obtained a foothold in ]^orth Carolina about as 

 soon as in Virginia, beginning at Southern Pines. Certain it is that it 

 has been kno-w^i in that vicinity since about 1897, and was probably 

 there several years before it was recognized. At the present time it is 

 widely disseminated in the State and no one can safely assume that his 

 locality is free from it. And this same condition is true in all the other 

 States in this section of the country. 



Name of the Insect. — It is worth while here to designate the proper 

 pronunciation of the name of this pest. The name San Jose is of 

 Spanish origin. The "San" is pronounced just as it is spelled. In the 

 word "Jose" the "J" has the sound of "H," the "s" the sound of "z," and 

 the "e" the sound of "ay." The proper way to pronounce the name of 

 the insect is therefore as if it were spelled "San Ho-zay," with the accent 

 on the last syllable.
