1904, it was known to be in 44 counties, and at present (April, 1907) 

 it is known to be in 57 counties out of a total of 98 in the State. 

 There can be little doubt that it is in most, if not all, of the others. 



NAME OF THE INSECT. 



Every recognized species of plant or animal has what is known as 

 a technical, or scientific, i^ame. The object of this is to have one 

 name (not subject to change or corruption by common use) by which 

 it shall be known all the world over. Most common, conspicuous, 

 or imjDortant species also have common names, which may be different 

 in different localities, by which they are known to the public. The 

 San Jose Scale has a scientific name and at least two common names 

 besides the one by which it is commonly kno"\^^l. 



Common Name. — When Prof. J. H. Comstock first discovered 

 the insect he said that it was "the most pernicious scale-insect" known 

 to him, and he proposed that it be called "The Pernicious Scale," 

 Owing to the fact, however, that it was discovered near the city of 

 San Jose, California, it came to be known as "The San Jose Scale." 

 Since it has been discovered that the insect was originally a native of 

 China, it has been suggested to call it "The Chinese Scale." We have, 

 therefore, three different common names by which this insect has been 

 called: (1) The Pernicious Scale, (2) The San Jose Scale, (3) The 

 Chinese Scale ; but of these the second is in much the most common 

 use. 



The name San Jose is of Spanish origin. The "San" is pro- 

 nounced 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, there- 

 fore, as if it were spelled "San Ho-zay," with the accent on the last 

 syllable. 



Scientific Name. — In science a plant or animal has two names, the 

 first being the name of the group, or genus, to which it belongs, and 

 the second being the special and particular name of that one species. 

 When Professor Comstock discovered the San Jose Scale, he recog- 

 nized that it belonged to the group or genus known as Aspidiotus, 

 and as he wanted its last name (which he as discoverer was entitled 

 to give it), he named it pernicious, on account of its pernicious nature. 

 In scientific parlance, therefore, the insect is known by the designa- 

 tion Aspidiotus pernicious, Comstock. 



APPEARANCE : HOW AND WHERE TO LOOK FOR IT. 



ITow that the matter of controlling the San Jose Scale has been 

 demonstrated to be so entirely practicable (even easy), probably the 

 one worst feature of the whole question is that the trouble is not
