THE REPOET OF THE

second brood that was responsible for these side injuries, in fact there was only 

 a very small' second brood this year even in Niagara district. 



It seems to me we may possibly account for the larger number of side 

 injuries this year in two ways. (1) There were very few apples and hence more 

 larvae would attack these apples than if there were a larger crop* (2) Many 

 of the moths emerged very late and laid their eggs after the pubescence was off 

 the little fruits, and in the absence of this entered the side of the apples much 

 more readily than if the pubescence had been present. A poison spray three 

 weeks after the blossoms fell gave good results this year in all cases where it was 

 well applied. 



The White-marked Tussock Moth (Remerocampfl leucostigma) . 



Judging from the number of egg masses to be seen this autumn the Tussock 

 Moth will be very abundant in many of our cities and larger towns next year. 

 Complaints have already come in from as far east as Belleville and as far west 

 as Goderich. In Toronto I counted 500 egg masses on a single maple tree in 

 the Exhibition Grounds. 



Not only are the egg masses abundant in cities and towns but also in many 

 orchards. One wide awake young fruit grower said to me a few days ago that 

 in his opinion this would be one of our main orchard pests next year in Western 

 Ontario. In Niagara it is likely to do a good deal of damage and if it is not 

 destroyed will in apple orchards injure a large percentage of fruit. 



Work on apples of the larvEe of the White-marked 

 Tussock-moth. 



In destroying the insect in orchards and for that matter also on shade trees, 

 a person is very likely to overlook the egg masses concealed in leaves. This 

 spring I asked my men to remove the eggs in one of our experimental orchards, 

 but did not call their attention to the leaves. On visiting the orchard again 

 I saw that these had been overlooked so that the work had to be done again. 

 Mr. W. E. Biggar, the Provincial Fruit ?ests Inspector, has used a small wire 

 brush about six inches long and one inch wide and fastened to the end of a pole. 

 A single stroke of this tears the egg masses to pieces. This brush has been used 

 in St. Catharines and some other places and given satisfaction. In my opinion 

 it is very good for the lower part of trees to the height of ,say. 15 or possibly 

 20 feet, but above that I think a hook, especially if toothed along the sides and 

 ends, will prove better. A test of crude creosote was used, but it seems to me
