22 THE REPORT OF THE .No. 19 



Mr. Caesar said he was afraid that no remedy could possibly ward off 

 attacks because he thought that winged females flew from plot to plot and 

 rendered all remedies more or less futile. 



Mr. Bethune : I think that it is the long continued dry weather that 

 has allowed the Apliids to become so very numerous and destructive this 

 year. It is very difficult to suggest a remedy to a farmer who is growing 

 turnips by the acre, because he will not apply a troublesome spray, and 

 what I recommend them all to do is to be on the lookout when they are 

 hoeing the crop and trample underfoot any affected foliage. Some farmers 

 said that their crops were entirely destroyed, while otliers said that the 

 turnips were all right though the foliage was very badly affected. 



Another insect which has been serious in a great many places is the 

 Turnip Maggot, similar to the Cabbage Maggot. These insects cause the 

 turnips to be all distorted and with woody or rotten spots. They are then 

 useless for any purpose as the cattle will not ^eat them and they are of no 

 use in any other way. I do not know any remedy that is really practicable 

 for dealing with this insect. 



The Bag Worm. 



Mr. Jarvis : I wish to call your attention to another insect that was 

 found by Eaymond Zavitz, of Guelph, this year, the Bag Worm. It was 

 found on a cherry tree. I think it has been found here for the first time. 

 I would like to hear what Dr. Felt says about this pest. "We have it here 

 this year and it is probably the first time that it has been reported in the 

 Province. I saw a note about its being found in New York State. 



Dr. Felt : The Bag Worm is in New York State, rather commonly 

 about New York City, and I should say off and on ranging rather abun- 

 dantly for thirty miles around. This last summer I was rather surprised to 

 receive the Bag Worm from Red Cedar, forty miles south of Albany. T 

 think it is an unusual record for New York State and just why you should 

 find the insect here I do not understand, because this must be equivalent 

 to about fifty miles further north than the latitude of Albany, and perhaps 

 the weather is a little more extreme in winter. 



Dr. Bethune : I had a specimen of the moth given to me two years ago, 

 which was taken in this part of Ontario and I thought it was extremely 

 remarkable. I never heard of the Bag Worms in Ontario before. Here in 

 Guelph we are just on the verge of the upper Austral and the Canadian 

 Boreal zones and we get a little of the fauna and flora of both zones, so that 

 we find a few insects reach us here that hardly extend further north or south, 

 as the case may be, and it seems we are free from most of the southern 

 species which are troublesome along the shores of Lake Erie. This insect 

 certainly is remarkable for having come to such a point as this. 



As far as these zones are concerned I suppose we are rather more than 

 fifty miles further north than Albany. It is never safe to say where the 

 line between these zones should be drawn. 



We find many things growing quite luxuriantly about .Dundas and in 

 the vicinity of Hamilton, which will not grow here at all. We are, I 

 think, about 1,100 feet above the level of the sea and are more than twice as 

 high above Lake Ontario as the Hamilton Mountain, so that there is a dif- 

 ference in altitude as well. 



After some further informal discussion on a variety of injurious insects, 

 the meeeting adjourned.
