THE SAN JOSE SCALE. LIFE HISTORY AND PRACTICAL 



REMEDIES. 



BY Pkof. H. a. Sl'RFACE. Econninic Zoologist. 



Mr. Chairman, Ladies and Gentlemen: In this State we are to-day 

 facing the most serious condition for the fruit interests that this 

 country has ever known and, perhaps, the worst that has ever 

 been known in the history of the earth. All kinds of fruit trees 

 are attacked by an insidious foe known as the San -Iob^ Scale, 

 which was imported into this country about fifteen years ago on 

 nursery stock from California and brought into this State about 

 ten or twelve years ago from the New Jersey nurseries. It took 

 a strong foothold in the fruit growing sections of the State, par- 

 ticularly in the southern, southeastern and eastern portions of the 

 Commonwealth. It has been greatly disseminated over the State 

 until now it is found in more than three-fourths of the counties and 

 our more extended knowledge of it may show it more practically 

 in all the counties of this State. In 1897, it was known to be in 

 the following counties: Bucks, Montgomery, Chester, Lancaster. 

 Dauphin, Columbia, Lycoming, Union, Snyder. Juniata, Perry, 

 Adams, Franklin, Blair, Cameron, Beaver, Erie, Montour and North- 

 umberland. In IS*!*.'-, it was known to be in tlie following ndditiennl 

 counties: Northampton, Lehigh, Philadelphia, Delaware, Lebanon, 

 York, Mifflin, Westmoreland, Fayette, Allegheny and Armstrong. 

 In 1903, we ascertained its presence in the following additional 

 counties: Bradford, Susquehanna, Sullivan, Wyoming, Lackawanna, 

 Luzerne, Carbon, Monroe, Schuylkill, Berks, Clinton, Huntingdon, 

 Bedford, Cambria, Clearfield, Mercer and Butler. It is not known 

 how much earlier than these dates it first occurred in these coun- 

 ties. But the first appearance of it in the State was in 1892 or 18^3. 

 There may be other infested counties at the present time and we 

 hope, by the co-operation of the members of this Board, to learn of 

 these at a date as early as possible.
