around the trunk a band of tanglefoot fly paper. A special preparation 

 known as ' ' tree tanglefoot ' ' is desirable for this purpose. The bands 

 should be about 9 inches wide and placed at a convenient height on the 

 trunk. These bands will not protect trees already infested, and where 

 branches intermingle there is always a chance for outside infestation re- 

 gardless of bands. 



The application of arsenical poisons to the foliage of trees already in- 

 fested with the larvae is also recommended. The main reliance, however, 

 should be placed on the destruction of egg masses and the banding of trees. 

 Spraying is not only expensive but difficult to accomplish satisfactorily in 

 case of large trees. Lead arsenate is preferable for this purpose. This 

 should be used at the rate of five pounds of lead arsenate paste to 50 gal- 

 lons of water.
