The Oblique Banded Leaf Roller. 



^'^ 669. Sir, — What shall I do for a worm that rolls up the leaves of currant and goose- 

 berry bushes, fastening the leaves up with a web. I have noticed it also on the leaves of 

 trees, e.g., the apple and plum. I send you a specimen. 



C. P. Morgan, Traro, N. S. 



Reply by Prof. James Fletcher ^ Central Experimental Farjn, Ottawa. 



The specimens sent by Mr. C. P. Morgan, from Truro, N. S., which he 

 had found so troublesome upon his currant and gooseberry bushes, of which 

 they rolled up the leaves and destroyed the foliage, are the caterpillars of the 

 Oblique banded Leaf Roller ( Cacoecia rosaceana^ Harris). This insect has been 

 rather more abundant and injurious this year than usual. It is sometimes a 

 troublesome pest upon apple trees. This year it has been sent to me as an 

 enemy of the birch, apple, pear, gooseberry and currant (it is always rather 

 abundant upon these), and a rather interesting attack, in which it destroyed the 

 seeds only of the silver maple. In fact this insect seems to be a pest on a very 

 large number of shrubs and trees, upon any one of which it may develop inju- 

 riously upon special occasions. The general practice of spraying fruit trees for 

 the codling moth and Leaf Roller, will certainly reduce very largely the occur- 

 rence of this pest, and spraying the bushes with Paris green, or any of the well- 

 known insecticides, will keep it in check. 



Seedling Currants. 



670. Sir, — I will mail you to-day some sample currants — 3 seedlings red — one of 

 which is the best in quality I ever saw ; to distinguish it I call it the Foundling. In size 

 it is about as large as the Cherry, but the bush being old and every available branch being 

 layered, it is not as large this season as formerly. It is an upright grower and very heavy 

 bearer. I send with them some others to test them by, as you may not have any on hand. 

 I am rather late in sending them, as currants left long on the bush tastes a little bitter. 

 I may also send a sample of red raspberry if I can find any on the bush ; it is one that I 

 crossed. 



F. W. Porter. 



The samples very much resemble the Cherry currant, but are too much 

 bruised to test the quality ; the raspberries are entirely mashed. They need 

 packing with cotton, so that they cannot move about. 



To Destroy Borers. 



6*71. Sir, — On page 269 you give Mr. Hillborn's method against the peach borer. 

 Would the same be effective against the currant borer ? If so, how should it be applied 

 Is there any certain method of dealing with this pest except cutting out the wood affected ? 



W. H. RowsoN, Burlington. 



We do not know of any experiments in this direction having yet been made. 

 The application to currants of this mixture with a brush would be too much
