Remedies. — Kerosene emulsion is the most effec- 

 tive insecticide with which to combat this insect. It 

 should be sprayed upon the infested trees early in 

 the season, before the aphides become too abundant. 

 The best time to apply it would be just after the 

 young lice hatch from the eggs; they are then very 

 tender and easily killed.
