THE IJEPORT OF THE Xo. 36 



Plum Curculio very plentiful iji })luui orchards tliis season, considerable 

 damage to apples. 



San Jose Scale appears to be considerabl}' winter killed during severe winter 

 of Januar}^, 1918, still quite plentiful in uncared for orchards. 



Tent caterpillar not common, few nests seen. Fall webworms rather plentiful. 



ApJiids. Considerable damage to tree fruits, very effectively controlled by 

 tobacco decoction. 



Peach tree borer very plentiful especially on trees which winter killed last 

 winter. 



Apple Maggot noticeably plentiful in one orchard, very little damage on the 

 whole. 



Fruits and Vegetables. Melon aphid an<l cucundjcr aphid again this 

 season accounted for a great loss among the cucumlier and melon growers hut 

 after the experience of last year a great many fields were saved by early spraying, 

 tobacco decoction being the most popular remedy. 



Onion thrips very ])lentiful in the Pelec marsh, no remedy as yet found 

 satisfactory. 



Onion root maggot again very plentiful, considerable acreage lost. 



Asparagus beetles plentiful but as the acreage is limited very little reported. 



Capsids were considered by Dr. Bethune to have been the cause of white 

 spots appearing on the early tomato crop. Upon careful examination no insects 

 wei"e found and no cause could l)e located. It occurred in two fields and accounted 

 for considerable loss. 



Squash bugs and cucumber beetles. Considerable loss to the pickle growers 

 resulted from these insects. Trapping was tried but with little success, application 

 of a repellant seemed to have only partial results. 



Greenhouse Insects. Greenhouse men experienced considerable trouble during 

 the winter of 1917-18 with greenhouse white fly and with aphids. Nematodes 

 were also plentiful. The best growers, however, practised soil sterilization and 

 occasionally fumigated with hydrocyanic gas. 



The President: I shall now ask Father Leopold to read his paper on 

 '"' Economic Entomology in Quel)ec." 



Father Leopold: Mr. President, I was so anxious to secure further informa- 

 tion on spraying that I did not prepare a paper but a series of questions which 

 I hope you and other entomologists who have been studying spray mixtures will 

 answer. I believe this will be of more value than my paper would have l)cen. 

 My questions are : — 



1. What spray mixtures should I recommend to our people next year for 

 apple orchards? 



2. Is it true that Bordeaux mixture causes very great injury by russeting 

 the fruit? If so, which application causes most of the russeting? 



3. What recommendations should be made in regard to dusting? 



The President: As neither Mr. Sanders nor Prof. Brittain are here from 

 Xova Scotia I shall ask Dr. Hewitt to tell us something about Mr. Sanders' 

 results and wdiat he intends to recommend this year in Xova Scotia. 



Dr. Hkavitt: I cannot, of course, respond to your request with as much 

 satisfaction to those who are interested m this subject as Mr. Sanders would liave 

 been able to aive had he been here.
