In economic Entomology there are imp' rtant papers by C. P. Lonnsbury on Insect Bites 

 ;(t;d thfir efl'ects ; T. I'ergande on a Plant-louse injurious to Violets ; Prof. F. M. Webster on 

 the Purs'ane Faw-fly, Harpalus caliginosus as a Strawberry Pest and the Diptera found in 

 wheat tields ; Prof. W G. Johnson on the Destructive Pea Aphis, and Prof G. H French on a 

 Fly causing Ejailepsy. 



En addition to the forejioing publications, a General Index to the thirty Annual Reports of 

 the Society (1870 to 1899) has been prepared by the editor, Rev. Dr. Bethune, and published by 

 the Ontar o Department of Agriculture. It is very full and complete and will prove of much 

 value to aU who have occasion to refer to these volumes. 



INJURIOUS INSPECTS OF THE SEASON OF 1901. 



Bv Prof. VV. Lochhead, Ontario Agricultural College, Guelfh. 

 Al•'FECTI^<; Farm Crops. 



In the south-west portion of the Province the wheat crop suffered severely from the attacks 

 of the Hessian fly. In several counties the yield per acre was very much reduced, notwith- 

 standing the plowing under of a large area both in the fall and spring. 



So urgent was the demand for more information regarding the life-history and habits of 

 the pest, that a bulletin was published by the Department of Agriculture in August, and distri- 

 buter! freely throughout the infested areas. This bulletin emphasized the great need for co- 

 operation among the farmtrs themselves, if they ever hoped to cope with the fly. Late sowing, 

 good preparation of the land to be sown to wheat, and trap-strips, will be found effective if al] 

 the tields are treated alike ; but if some tields are sown early and become infested with the fly in 

 the fall, there is no way of preventing the flies which emerge from these fields in May from 

 migrating to uninfested fields and damaging them before harvest. 



Orchard Insects. 



As in previous years, the codling worm (Fig. 17). was the most destructive orchard insect, 

 especially in the sections where the insect is double-brooded. A word of warning maybe given 

 here, lest owners of orchards become lax in the matter of spraying with Paris green immediately 

 after blossoming, while attempting to entrap the second brood by bandages. We c-in never 

 afford to give up spraying* with Bordeaux and Paris green, for by doing so the codling worm 

 and fungus diseases are kept in check. The frequent rains about the blossoming period inter- 

 fered with the spraying operations, and when the applications were not renewed, the effect of 

 'he Paris green was very slight indeed.
