REPORT OP THE ECONOMIC ZOOLOGIST. 



Hariisbuig, Pa., January 1, 19U3. 

 Hon. John IhwmWou, Secretary of Agi'iculture: 



My Dear Sir: 1 luivc the honor to submit a review of the work of 

 the Division of Zoology for the year ending December 31, 11)02. 



The general routine work of the ottiee has consisted in the de- 

 termination of material sent in, the mailing of bulletins, the ac- 

 quisition of additional names of orohardists, farm gardeners and nur- 

 serymen to those already on file, the attention to the general cor- 

 respondence connected with the Division and the work iovolved 

 through the inspection of nurseries. 



The interest taken by orchardists, nurserymen and others relative 

 to the spread and control of the San Jos^- Scale and other injurious 

 tree and kindred diseases is certainly very gratifying. The Division 

 very frequently is in receipt of infested specimens, and it is apparent 

 that persons interested along these lines are awakening to the fact, 

 gained by actual experience, that individual effort has become essen- 

 tial in the treatment of tree diseases in order to successfully counter- 

 act the inevitable loss due to ignorance and carelessness. In order 

 to L^row trees which will produce good salable fruit, it is absolutely 

 necessary to see that the tree is constantly kept in a healthy condi- 

 tion, by taking such measures as will effectually dispose of all in- 

 jurious insects and tree diseases which may have a tendency to re- 

 tard the good results to be obtained under favorable conditions. 

 The fruit growing industry in Pennsylvania is of vast importance, 

 and we tind an ever increasing and a profitable market for choice 

 fruits such as this State is capable of producing. 



The Division has afforded assistance in every way possible to 

 farmers and fruit growers, by placing at their disposal and dissem- 

 inating such information, that will nuike possible for them to fully 

 understand and put into practice such remedial measures as has 

 been suggested. The San .Jos*' Scale predominates to a very large ex- 

 tent, it being reported from nearly every portion of the iState. Of 

 course there are sections where it exists to a very small degree, while 

 in other parts it is very prevalent, notably in eastern Pennsylvania, 

 wliere fruit growing is carried on to a greater extent, and where 

 tlie majority of the nurseries are located. The interest taken in the 

 suppression of the San Jos«^ Scale is widespread, the nurserymen 

 particularly are doing efficient work for its eradication. Of course
