368 EXPEEIMENT STATION RECORD. [Vol.38 



The black peach aphis, which was very prevalent during the year, was found 

 to be best controlled by the use of 40 per cent nicotin sulphate solution, reduced 

 at the rate of 1 to 500, with 0.5 lb. laundry soap dissolved in each 3 gal. of the 

 reduction. The rose chafer, which caused considerable injury to young 

 peaches, eating from one-third to two-thirds of the fruit, was quite satisfac- 

 torily controlled by the u.se of 6 lbs. of arsenate of lead to 50 gal. of water, 

 sweetened with 1 gal. sorghum. The ash-gray blister beetle, which occurred 

 in swanns in parts of east Tennessee, caused considerable loss to alfalfa, soy 

 beans, and cowpeas. It was disseminated by cutting the crop at the time of 

 the attack, there being no known case of a second infestation occurring in the 

 same field. 



In experiments at the station apiary it was found that bees In double-wall 

 hives come through the winter much stronger than those in the single-wall 

 hives and with 25 per cent less honey required to feed them.

 on the browTi-tail moth, which is said to be the most injurious pest in Nova 

 Scotia; the dock sawfly (Ametastegia glabrata), first recognized as a serious 

 pest in the winter of 1915-16; the leaf sewer (Ancylis nubeculana), widely 

 distributed throughout the Province, which in one orchard during the previous 

 season attacked 90 per cent of the leaves ; the tussock moth, severe outbreaks of 

 which occur once in every eight or ten years ; and the cankerworm, which almost 

 totally defoliated many orchards during 1915 and was even more injurious dur- 

 ing 1916.
