imported into Canada without its native parasites it may prove a 

 very injurious pest in the future. Nygmia phaeorrhoea, Don. (brown- 

 tail moth), the cankerworm and the tussock moth are also dealt with 

 in respect to their prevalence during the year under review.

This paper records the first experiments in dusting apples in Nova 

 Scotia. The results indicate that dusting is undoubtedly a superior 

 method to lime-sulphur spraying, and it is thought that the former 

 method will be largely employed as soon as it has been proved successful 

 in controlUng apple scab under Nova Scotia conditions at all seasons.

Some figures are given illustrating the steady decrease in the numbers 

 of Nygmia phaeorrhoea (bro\Mi-tail moth). Other species dealt w4th 

 are Ametastegia glahrala (dock saw-fly) [see this Review, Ser. A, v, p. 241], 

 Ancylis nubecidana (leaf-sewer) [see this Review, Ser. A, v, p. 106],

The question of dusting versus spraying is discussed, chiefly with 

 regard to apple scab infestation. The work in connection with green
