of hay or paper. When bands are used, other places in which the 

 larvffi might spin cocoons should be destroyed or rendered unsuitable. 

 It is, of course, a most important point that the larvse which go under 

 the bands be destroyed. To accomplish this the bands should be 

 inspected regularly at intervals of ten days. At best, banding is but 

 little effective in badly infested localities if used alone, but it is a most 

 valuable adjunct to spraying. 



CONCLUSION. 



The results secured against this insect b}' these methods under the 

 different conditions found in the various apple sections of the United 

 States are very satisfactory. In the infested sections of the far West, 

 if no measures are used, from 85 to 100 per cent of the fruit is injured. 

 By an intelligent application of these preventive and remedial meas- 

 ures many practical tests show that from 85 to 98 per cent of the 

 fruit may be saved.
