the trees are to be treated for scab, the Paris green may be com- 

 bined witli the Bordeaux mixture. 



As previously stated the female moth is wingless and must crawl 

 up the tree if she deposits her eggs on the branches. Advantage 

 is taken of this condition and traps arfe used to prevent the female 

 moths from ascending the tree. Cloth or paper bands five or six 

 inches wide, made sticky with tar, printers' ink or some other sticky 

 substance, are fastened around the trunks of the trees. Care should 

 be taken to leave no ci-evice under the band through which either 

 the moths or the young worms might crawl. The bands must be in 

 position to catch those moths which emerge on warm days in spring, 

 sometimes before the snow is all gone and they must be examined 

 every two or three days if necessary, smearing them afresh and 

 keeping them in working condition. Bands of raw cotton or of 

 wool have also been advocated for this purpose. 



In opposing this insect it should be remembered that prevention 

 is better than cure and the trees should be sprayed regularly with 

 arsenites each season as advocated for the codling moth and bud 

 moth. Where an orchard has been allowed to become badly 

 infested, probably more than one season's work will be necessary to 

 free it from this pest and all practical remedies should be used 

 vigorously and thoroughly. 



Case Bearer. — The larvse of this curious insect may be found in 

 the spring attached to the twigs in what Saunders^ describes as 

 a pistol-shaped case. As the buds begin to swell, tlie insect com- 

 mences to feed on them, often leaving nothing but the empty shell. 

 Later on they move to the leaves and continue their depredations. 

 Here they may be seen with their heads attached to the leaves on 

 which they are feeding and the cases containing their bodies pro- 

 jecting out from the surface of the leaves. 



Remedy. — In some sections of the State these insects have 

 appeared in sufficient numbers to damage the foliage to a consider- 

 able extent. In orchards where they are so numerous as this Paris 

 green should be applied when the buds begin to open as recom- 

 mended for the bud moth. If in addition to this treatment Paris 

 green be used with Bordeaux mixture in the apple scab treatment 

 this insect will probably be held in check. 



Codrng Motlj. — The adult insect is a small brown moth that
