of active life the young settle down and the protective scale is 

 formed. By the middle of June the females become mature, and 

 about that time the red-bodied, transparent-winged males 

 emerge. The second brood of eggs is laid the last of June, and 

 a third at the end of August ; females of the last brood become 

 mature in late October, in which condition hibernation takes 

 place. There are thus three generations at Washington, while 

 in Florida and Georgia there are said to be four broods. 



Treatment. 



Lime-sulfur as used against the San Jose scale has been found 

 satisfactory for the control of this pest. The use of dilute Ume- 

 sulfur for the control of brown rot would do much to prevent 

 the young from establishing themselves on the bark. The 

 young may also be killed by summer applications of whale-oil 

 soap, kerosene emulsion or tobacco extracts.
