Results. An insignificant percentage of the buds were destroyed in this 

 patch and a splendid crop of berries was harvested — about 350 crates per acre. 

 ]n a patch about l^ mile from Mr. Church's at least 60 per cent, of the buds wore 

 destroyed by the weevil and the yield was only 100 crates per acre. 



Results in Other Steawbekry Patches. 



In every strawberry field where the dust was put on at the right time excel- 

 lent control was obtained. All the growers who used tlie dust remedy expressed 

 themselves as beino- well satisfied with the results. 



INSECTS OF THE SEASON IN ONTARIO.

The past year was a notable one from the entomologist's point of view. The 

 mild winter of 1918-19 and the hot, dry summer were very favourable to insect 

 life, and consequently injurious insects of many kinds were numerous.

Orchard Insects. 



It is worth while noting here that the carefully and regularly sprayed apple 

 orchards were practically the only ones which had crops of fruit this year. 



Codling Moth (Cydia pomo7ieUa). This well-known pest was very much 

 more abundant than usual and caused great loss in the warmer parts of the 

 Province where the percentage of second brood is largest. Some unsprayed orchards 

 in the Niagara District had almost every apple infested. Orchards, well sprayed 

 this year, but which in preceding years had been neglected or poorly sprayed had 

 as high as 50 per cent. " sideworm injury." On the other hand, orchards in 

 districts that had been well sprayed for several years suffered little injury, tlms 

 showing the cumulative effects of good spraying. 



Cigar Case-bearer (Coleopliora fletcherella). This species is usually of 

 comparatively small importance, even in unsprayed orchards, but this year it was 

 present in very large numbers and made the foliage of unsprayed trees ver}' tattered 

 and unsightly.
