Banding'. 



The use of bands to trap the full-grown hxrvfe of the codling moth 

 was the only remedial measure of value eraploj'ed before arsenical 

 sprays were discovered. If an orchard has been given good care, and 

 spraying is thoroughly done, it may be unnecessary to use bands. If, 

 however, the trees are old and cracked, and have holes in the trunks 

 and branches, or are planted close together, so that spraying is diiBcult, 



the use of bands 



will materially aid 



'wringing the in- 



in 



sect under control. 



Banding for this 

 insect is simply af- 

 fording it a good 

 place to spin its 

 cocoon, and killing 

 the larva or pupa 

 after it has gone 

 beneath the band. 

 Cloth bands, from 

 10 to 12 inches in 

 width, are folded 

 once lengthwise and 

 placed around the 

 tree. They can be 

 fastened in such a 

 way as to be easily 

 removed and re- 

 placed, by driving 

 a nail through the 

 ends and then nip- 

 ping off the head 

 at an angle so as to 

 leave a sharp point.

If a tree is large, one band should be placed on the trunk and one on 

 each of the larger limbs (fig. 2). Cloth bands of any heavy, dark- 

 colored stuff are much preferable to bands of hay or paper. When 

 bands are used, the trees should be scraped clean of rough or loose 

 bark, to leave as few other attractive places as possible in which the 

 larva? might spin cocoons. Inspection of the bands should be made 

 regularly at intervals of ten days, and all larvae and pupes found 

 beneath them should be destroyed with a knife. If used alone, band- 

 ing is but little effective in badly infested localities, but it is a most 

 valuable adjunct to spraying. Under no circumstances should band- 

 ing be used as a substitute for spraying.
