fS.I The young worms again eat tlieiv way into the apples, and remain 

 insiili" the fruit for another twenty days or so. The first brood enters the 

 apple mainly by the caliix cud ; hence the necessity of having the poison well 

 down in the calyx cup and ready for them. The second lirood enters the 

 apple anywhere, but usually not by the calyx. When the mature worm 

 emerges from the apple again he does not. about Moscow, change again this 

 season into the moth, but seelis a hiding-place, spins about him his cocoon, 

 and there spends the winter. Rarely they remain in the apple when stored. —

The following is from the V. S. Farmers' Bulletin, No. 247: — 



li(tndin<i. — The use of bauds to trap the full grown larva? of the codling 

 moth was the onl.v remedial measure of value employed before arsenical spra.vs 

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

 thoroughly done, it may be unnecessary to use Viands. 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 diflicult, the use of bands will materially 

 aid ill bringing the insect under control. 



Handing for this insect is simpl.y affording 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 lengthwi.se and 

 placed around the tree. They can lie fastened in such a way as to be easily 

 removed and replaced, liy driving a nail through the ends and then nipping 

 off tlie 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 linilis. Cloth 

 liands of an.v heavy dark-coloured stuff are much preferable to bands of hay 

 or jiaiier. 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 

 larvre might spin cocoons. Inspection of the bands should be made regularly 

 at intervals of ten days, and all lar\Te and pup,'e found beneath them should 

 be destro.ved with a knife. If used alone, liandiug is but little effective in 

 badly infested localities, but it is a most valuable ad.lunct to spraying. Under 

 uo circumstances sliould banding be used as a substitute for spra.ving. 



The use of ar.senate of lead for the codling moth is thus referred to in the 

 New Zealand Agricultural Iteport, 1007 : — 



" HiiriiiiiiKi fur Codliitu Moth. 



" Such excellent results in the control of the moth have been derived 

 through sjiraying with disparene (which Is onl.v another name for arsenate of 

 lead ) that it seems jn'obable that either disparene or Swift's arsenate of lead 

 will take the place of other forms of arsenic as an insecticide for codling
