The Woolly Aphis. 



Prof. HuTT brought up the subject by remarking that the Woolly Aphis 

 was very abundant this year in some districts. 



Mr. Jarvis : I should think it was. In the orchards around here nearly 

 every young tree has every little crevice or wound on the bark filled with 

 them. 



Mr. Crovs^ : I have noticed that they are very bad in the College orchard, 

 but I do not think they have injured the trees much. 



Br. Fletcher: When did you notice that they were numerous? Was 

 it in summer or autumn"? 



Mr. Jarvis : In autumn. 



Dr. Fletcher : Has anyone ever found the WooHy A^nis in the root 

 form in Canada? Personally I never have, though it is found in the United 

 States and does much injury there. 



Mr. Frier : When we were taking up some young conifers in the 

 Forestry Department this year, we found a great number of Woolly Aphids 

 amoncr the roots. Would these be the kind you refer to? 



Dr. Fletcher: No, these are a different species. "Woolly aphids" are 

 found on many kinds of trees and there are many different species. 



Prof. HuTT : It is very interesting to see the chickadees eating these 

 insects. They seem to devour them with great relish, and soon destroy a 

 great number of them. 



Bees and the Yield of Frttit. 



Prof. HuTT : I should like to call the attention of members to the lack 

 of bees for fertilization this year. I am told that in many districts nearly 

 80 per cent, of the bees perished during the winter or early spring. Added 

 to this the fact, that during the blossoming season we only had a few really 

 good days for the bees to work. I believe it was owing to this that so smajl 

 an amount of fruit set this year, smaller than usual. I firmly believe that 

 fruit-growers should keep more bees. I notice that men who keep bees have 

 a better set of fruit. Mr. Dempsey, of Trenton, is a good example of these 

 men. He has bees and never fails to get a good set of fruit. 



Dr. Fletcher: I am glad you brought this subject up. Mr. Macoun, 

 of the Experimental Farm at Ottawa, called my attention to the splendid 

 crop of apples we had this season, whereas the apple crop for miles around 

 Ottawa was almost a failure. The only explanation I can find is that we 

 had bees to help us and other people had not. 



Prof. HuTT : Do wild bees assist to any extent in the fertilization of 

 fruit blossoms? 



Dr. Fletcher : Certainly, but not to the same extent individually as 

 the honey bee. The latter seems to be especially liuilt for this purpose. He 

 seems to delight in getting covered all over with pollen and conveying it from 

 one blossom to another. 



Dr. Brodie : Many families of wild bees do a great and excellent work 

 in fertilization: especially is this true of the great family Andrenidae, of 

 which there are about 100 species; the Syrphidse and Halictus, also, do good 

 work in fertilizing fruit Blossoms, 



San Jose Scale. 



A short discussion on this scale was brought about by the reading of thb 

 following letter from Mr. J. Fred. Smith, San Tos6 Scale Inspector for On- 

 tario :
