REMEDIES. 397 



you reach the ground. This done, gather the scrapings care- 

 fully off the cloth, so that they can be burned or otherwise 

 destroyed immediately. 



Be careful that you do not neglect gathering carefully the 

 scrapings and destroying them, as on this point depends a 

 great deal of your success. By thus burning the debris taken 

 from the trees the larvte hibernating in the debris are de- 

 stroyed. 



B. After having completed scraping off the loose bark, the 

 trunk and limbs should be thoroughly washed or sprayed 

 (providing the tree is only treated against the codlin moth). 

 If the woolly aphis or scale insects are present, the whole tree 

 should be sprayed with No. 11 or No. 12, one pound of either 

 mixture to each gallon of water used. If projjerly applied, 

 this will destroy any larvte on the tree, and also produce a 

 new smooth bark. See No. '11. 



C. Not later than the 10th of May, bands should be placed 

 (.)n the trees as follows : 



Cut old grain sacks or cloth in strips from six to eight inches 

 wide, and place a band on each tree near the ground. (It is 

 expected that the rough bark has been scraped off between 

 the band and the ground). The fastening cord or wire should 

 be as near the upper edge as possible, allowing the lower edge 

 to spread out from the tree, say a cpiarter of an inch or so. 

 Paper will do for bands, but cloth is preferable. Pieces of old 

 sack, oY rags, should be placed in the crotches. The larvae, 

 after leaving the fruit, when looking for a place in which to 

 pass their transformations, will hide under the bands on the 

 trees, or the rags in the crotches, and make their cocoons or 

 nests. The bands and material in the crotches should be 

 examined every seventh day, without fail, and all the larva^ 

 found on them picked off and destroved. 



D. Note. — Notwithstanding the fact that recommendations 

 have been made that it is not necessary to examine the bands, 

 etc., every seventh da}^, the following fact would seem to indicate 

 otherwise ; a larva which I caught changed to a pupa on the 

 2Sth of June, 1883, and the moth emerged from the pupa on 

 July 6th ; length of time spent in the pupa state, less than 

 eight davs.
