1913 ENTOMOLOGICAL SOCIETY. 75 



The varieties worst injured by egg punctures were Tolman's Sweet, Greening, 

 Golden Eusset, Ben Davis, Alexander, and Duchess. The worst injured by feeding 

 were Tolman's Sweet and Alexander. They were extremely injurious to Bartlett 

 Pears. 



I have nothing to oi!er in the way of remedies, because I have not performed 

 any experiments as yet in cultivation or spraying. Jarring is offered by Sanderson 

 as a remedy. How effective this may be on young trees, I cannot say, but to 

 shake them from old trees would result in a large loss of fruit because they hold 

 to it so firmly. 



My reasons for dealing at such length on this insect are : first, it has not 

 received any careful investigation; and, secondly, it is the most injurious insect 

 on apples and pears in this portion of Quebec. 



INSECTS OF THE SEASON IN ONTARIO. 



L. Caesar, B.A., B.S.A., Guelph. 



With a few exceptions this season has been comparatively fr^e from any 

 serious insect injuries, several of our worst pests being much less destructive than 

 usual. 



Orchard Insects. 



Codling Moth (Carpocapsa pomonella). This insect ha? not been so abun- 

 dant as usual, prohably because the wet, cold season retarded development and so 

 lessened the percentage of the second brood. Each year very gratifying progress 

 is being made in the number of fruit growers who are meeting with excellent 

 success in controlling the Codling Moths by thorough spraying. It is worth 

 noting that only those who spray very thoroughly, so that the trees having much 

 bloom are literally drenched, are getting really satisfactory results. This sort of 

 spraying is also giving us apples free from scab and no injurious results are 

 reported from it. I do not recommend so heavy spraying for any later applications 

 that may be given. 



Lesser Apple Worm (Enannonia prunivora). This caterpillar which so 

 closely resembles the codling moth larva is found in abundance almost every year 

 in haws. It is apparently not very destructive to apples in the Province. I have 

 found it attacking apples at Guelph and in the Niagara District. This year 

 infested apples were sent in from Prince Edward County on July 7 which con- 

 tained larvae almost full grown. Both of these had entered by the calyx end and 

 were feeding a short distance below the inner cavity. I mention this as indicating 

 that these larvse evidently mature about as early as the earliest Codling Moth 

 larvse. There is, of course, a second brood. I also found the larva in sour cherries 

 this year at St. Catharines. 



Plum CtJRCULio {Conotrachelus nenuphar). As usual, much damage was 

 done by this beetle to cherries, plums, peaches, apples, and pears. I did not, how- 

 ever, see so many evidences of its fall work on apples as usual: whether this was 

 due to the wet weather I cannot say. Apricots, wherever grown in the Niagara 

 District, seem to be particularly attractive to the Curculio.
