We have often found the younf^' wood 

 of the peach and apple affected, but 

 to no serious extent, by the same in- 

 sect. The only remedy yet suggested 

 worth using is the one our corres- 

 pondent has been doing, viz : to cut 

 off the limbs that are stung, and 

 burn them up, eggs and all.

 ing this insect, see " Saunders Insects 

 Injurious to Fruits," 2nd edition, p.

34. Can strawberries be raised successfully 

 beneath trees ? — ^W.A.Brownlee.M/. Forest. 



No. Strawberries must have open 

 ground for successful cultivation. 



Duty on Garden Seeds and Nursery 

 Stock 



35. Can you tell me what is the duty, if 

 any, on garden seeds and nursery stock ? — 

 C.B. Parker, Mt. Brydgcs, Out. 



Major Anderson, surveyor, H.M's. 

 Customs, Grimsby, says garden, field, 

 and other seeds for agricultural pur- 

 poses—not otherwise provided for, 

 when in bulk or large parcels — fifteen 

 per cent, ad vnlonni ; when put up 

 in small papers or parcels, twenty- 

 five per cent. 



The Bud Moth 



36. For some years an insect has injured 

 my apple and other fruit trees by laying an 

 egg in the bud. In Spiing, it hatches, and 

 the bud expands and glues the young leaf 

 tips together, preventing growth. Within 

 this I find a small red worm which matures 

 in a few weeks, then by a small silken thread 

 descends to the ground. In vain have I 

 searched all my entomological works for a 

 description of this pest. Would you, Mr. 

 Kditor, or some reader of your instructive 

 Hortici;ltur!st, name this insect and sug- 

 gest a remedy for its increasing depredations ?

I quite agree with you that the 

 moth mentioned in Mr. Coleman's 

 letter, is Tmetocera occllatia and per- 

 haps after all it may have the habit 

 of occasionally letting itself down bv 

 a silken thread. Of course it Leathers 



together the leaves amongst which it 

 feeds with this material. I should 

 refer him to Saunders' book for the 

 remedies, under the head of " Eye- 

 spotted Hud- Moth. I have an idea 

 that much good might be done by 

 spraying a kerosene emulsion over 

 apple trees just before the buds ex- 

 pand. I believe that this insect 

 hibernates on the twigs as a larva 

 and that it, the oystershell bark-louse, 

 the apple aphis (then in the egg state), 

 and many other insects would thus 

 be destro}'ed. At any rate it is 

 worth fruit growers trying the 

 experiment. 



The Pea Weevil 



37. I AM told that the pea weevil cannot 

 endure a temperature of 15° below zero. 

 Can you give me any definite information on 

 this point ? — G. F. , Fnrmaii P.O.

 mental Farm, Ottawa. 



I am unable to find any mention 

 of the fact that Bnichns fisi cannot 

 stand a temperature of 15° Faren- 

 heit. I have tried in vain to get 

 either infested peas or a temperature 

 so low as that this year, since you 

 wrote. However, I believe that the 

 grain weevils Callandra ozzie and 

 C. irranaria are imable to withstand 

 low temperatures, and it is possible 

 that B. pisi ma}- also succumb to the 

 same easy treatment. Undoubtedly 

 the easiest and best treatment is to 

 subject the seed to the I>isulphide of 

 Carbon treatment, which consists of 

 putting about a bushel of seed in any 

 tight receptacle and then placing on 

 the top any small vessel which will 

 hold about half a wine-glass of Bi- 

 sulphide of Carbon. Tiiis will eva- 

 porate in about twelve hours and the 

 heavy vapor will fall down and per- 

 meate the whole measure of seed. 

 This vapor is extremely inflammable 

 and the operation should be carried 

 on out of doors in a shed, and the 

 seed emptied out in the open air 

 away from all fire. The vessel should 

 be kept closed for forty-eight hours 

 when every insect will be destroved.
