can be obtained from the State Insectary. Ashes or lime placed on 

 the damp vines is recommended. 



The Black Peach Aphis and the Wolly Aphis attack both the 

 top and the roots, the Black Peach Aphis attacking peach and other 

 stone fruit trees, and the Woolly Aphis attacking apple trees. 



The Black Peach Aphis seems not to be seriously regarded in 

 the East, but on sandy soils of this County, it has caused much 

 alarm and some trees have been killed to stop it from spreading. 



Wooly Aphis (Schizoneura lanigera Hausm) ; a.-root in- 

 jury by the underground form ; b. -wingless female; 

 c.-winged female. (U. S. Dept. Agrcl.) 



Black Peach Aphis (Aphis persicae-niger) 



The only remedy here seems to be a solution of potassium cyanide 

 placed in a trench around the roots of the tree, or carbon bisulphide 

 put about one foot below the surface, close to the tap root, and 

 either remedy is quite likely to kill the tree, though the cyanide is 

 least severe. In each case the top should be sprayed well with 

 krosene emulsion at the same time. 



The Woolly Aphis is controlled by the application of wood ashes, 

 tobacco stems, or kerosene emulsion about the roots near the 

 tree, and the kerosene emulsion spray for the top. This treat- 

 ment is recommended by many authorities for the Black Peach 

 Aphis, but it is not efficient here for this species. 



The swollen yellow bodies of the Orange and Rose Aphis, with 

 a hole in the top of each, show the work of the parasitic fly which 

 keeps them in control, and if any treatment is needed, tobacco 

 solution will do the work.
