We hope and expect that the wet weather we have had this fall along Avitli 

 lliL' coming winter will reduce the hibernating adnlts to insignificant proportions. 



CiiAMBiD Attacking Wheat (Cramhus mliglnosellus).* In the seven-acre 

 field of wheat in AVainfleet Township, Welland County, over 60 per cent, of ilie 

 wheat was destroyed by a crambid or sod-worm. Because of the very wet spring 

 this particular field was not worked until August and as a result had been covered 

 with weeds and grasses most of the year. One-half of the field was ploughed about 

 August 1st. This part was not seriously injured. The other half was not ploughed 

 until the middle uP August and in this the wheat was so badly damaged that it 

 had to be rcsown. 



Clover Seed Ciialcis {Bruchophagus fimehris). Judging from samples of 

 f?ced sent in last winter from Kent County, this insect must have been very abund- 

 ant there in ]918. One correspondent claimed that much of the seed produced 

 in Kent County ^\as destroyed by this tin}' insect.

 and short-winged forms of the

Glassy Cutwokm {Sidemia devasiatrix). This cutworm caused some alarm 

 in Middlesex County in mid-June by cutting oft' wheat plants. Tlie total loss, 

 however, was not great. 



Hessian Fly (Mayctiola destructor). So far as observed, this insect did nut 

 cause any appreciable injury in any district. In several fields approximately 

 r") ])er cent, of the plants were attacked. 



Miscellaneous. 



Warble Flies (Ilypod^rina hovis and H. lineatum) threatened to be very 

 numerous judging 1iy the great numbers of warbles seen on the backs of cattle 

 in i\iQ spring. Fortunately the danger so far, at least, as the heel fly was concerned 

 did not materialize, and very few complaints of cattle gadding were received. 



Spruce Gall Lice (Chermes ahietis and C. similis). Galls caused by those 

 insects were somewhat more conspicuous than they have been for several years. 

 There are evidently ])owerful natural factors keejnng these insects under control. 



Grasshoppers. Few complaints were received regarding grasshoppers or 

 locusts. In the Smithville district, however, these pests were more abundant than 

 they had been for many years. Garden crops, alfalfa and oats were very freely 

 attacked. 



Cotton Worm (Alabama argillacea). IMoths of this species visittd many 

 faifs of Ontario this autumn and attracted considerable attention. 



*Species determined by Dr. McDunnough.
