This scale insect occurs in spariuL^ numbers in the southern portions of 

 New York State and occasionally becomes somewhat abundant on rose, 

 raspberry and blackberry bushes. It begins to breed in Pennsylvania about 

 the middle of May, and in New York the young may be expected the 

 latter part of the month and for several weeks thereafter. Thorough 

 spraying with a kerosene emulsion or whale oil soap solution should be 

 effective in checking this scale insect whenever it is at all abundant. \Scc
