1911 ENTOMOLOGICAL SOCIETY. 19 



It is rather remarkable that plant lice, which were responsible for consider- 

 able damage in the orchard and field in 1909, were scarcely in evidence this season. 

 The same is true of the cutworms and the codling moth. 



Slight exceptions to the general freedom from insect pests were the Colorado 

 potato beetles, which were unusually abundant. Some complaint was also made 

 of the ravages of the Cankerworm {Paleacrita vcrnata), which did some injury 

 to the beech, maple and apple trees. Maple trees in Gait and vicinity have been 

 attacked by the Pigeon Tremex (Tremex columha), but investigation showed that 

 no very serious injury has been done. 



Division 'No. 3, Toronto District — J. B. Williams, Toronto. 



I have been away in England most of the summer; so that the only matter 

 on which I can report anything is the well-worn subject of the Tussock Moth. 



These insects have been very numerous in Toronto during the past summer, 

 and I have noticed quite a large number of trees that have been seriously damaged by 

 tliem, notliing being left on large portions of the foliage, except the veins of the 

 leaves. 



Our Park Commissioner obtained, this autumn, a grant of $3,500 for the 

 purpoee of collecting the egg masses of the cocoons; and, I believe, he is employ- 

 ing three gangs of men in this work as long as the fund lasts; but the egg masses 

 must be more generally collected in the private grounds and gardens of t!he city 

 if the work is to be really successful. 



Great numbers of the cocoons this year were found on two apple trees in the 

 garden of the house where I live, though there were no signs that the caterpillars 

 had been feeding on the leaves of these trees. I picked a large handful of the 

 egg masses off them a few days ago ; and so did a little towards the destruction of 

 this troublesome pest. 



Division No. 7, Niagara District — E. C. Treherne. 



I have the honour to present my first report as representative for the Niagara 

 District. 



I regret to say that my report must be lacking in detail, for the reason that 

 I have been absent from the district for a greater part of the summer, consequently 

 I am compiling this report with the assistance of friends residing in the district 

 and from a few notes I had in hand previous to leaving the district. 



The fruit-growers of the Niagara district are still greatly troubled by several 

 very serious insect pests. There are four insects which are present every year, and 

 which, I regretfully have to believe, are yearly increasing over a larger area. These 

 four are — 



1. The Codling Moth (Carpocapsa pomonella). 



2. The Plum Curculio (Conotrachelus nenuphar). 



3. The San Jose Scale (Aspidiotus perniciosus). 



4. Shot Hole Borer {Scohjtus rugulosus). 



In none of these cases am I able to give figures or statistics, showing effects 

 of spraying or degrees of infestation. I can merely mention them as being the 

 most serious pests with which the fruit-grower has to contend. 



The Codling Moth has been more than ever abundant this year, especially 

 so in unsprayed orchards. Even in cases where orchards have been sprayed at the
