Grains and Clovers. 



The Feit Fly (Oscinis carhonaria) along with the Wheat Stem Maggot 

 {Meromyza americana) caused appreciable injury to small grains. These insects 

 which have not, at least within recent years, been destructive in this region were 

 more plentiful than usual. 



Hessian Fly injury was observed by Mr. P. I. Bryce in the experimental 

 plots at Macdonald College. Hitherto these plots have been free from this pest. 

 As the plots worst affected were in the neighborhood of a manure pile it is prac- 

 tically certain that the insects were brought in with the manure. 



The more important insects of the clover during the season were the Clover 

 Seed Chalcid (Bruchophagus funehris), The Lesser Leaf Weevil {Phytonomus 

 nigirostris). The Clover Mite {Bryobia pratensis), The Pea Aphis 

 (Macrosiphum pisi), and Tychkis picirostris. The Seed Chalcid was quite des- 

 tructive during the seasons of 1913 and 1914. The injury due to it was not so 

 marked during the season under discussion, but its work was supplemented by 

 that of the Lesser Clover-leaf Weevil, the larvae of which destroyed a fair pro- 

 portion of the red clover seed. The Clover Mite was quite abundant in the latter 

 part of the season. 



Locusts. The locust outbreak was very severe in the Province of Quebec 

 during the past season. Not only forage and field crops, but some garden crops 

 were severely injured. The species most numerous and causing most injury at 

 Ste. Anne's was the red-legged locust (Melanoplus femur-ruhrum) . M. hivittatus 

 was also quite numerous. At Macdonald College the poisoned bran mash, Kansas 

 formula, was used to protect the experimental plots. For some reason the 

 mortality among the locusts was not as high as expected. The incursion of locusts 

 from neighboring untreated fields increased the difficulty of controlling the pest 

 and for this reason strong emphasis should be laid on co-operation among farmers 

 in combatting these insects. 



Field and Garden Crops. 



Cutworms. Another very serious outbreak of cutworms occurred in parts 

 of the Province, causing considsrable injury to garden and field crops. At Ste. 

 Anne's the species responsible for most of the injury was the striped cutworm 

 {Euxoa tessellata), but a few white cutworms and red-backed cutworms were also 

 found. Several parasites of these insects were actively at work, and the relatively 

 small number of moths observed holds out some hope that the cutworms will be 

 less destructive next year. 



Boot Maggots. Both the cabbage root maggot (Chortophila Irassicce) and 

 the seed corn maggot {Chortophila fusciceps) were the cause of much injury to 

 cruciferous crops. In some turnip fields a large proportion of the plants was 

 destroyed by the seed corn maggot even after the tops were practically full grown 

 and the roots had attained a fair size. The carrot rust fly (Psila rosce) was more 

 injurious than usual this year, causing considerable loss in small kitchen gardens. 



The Beet-Leaf Miner (Chortophila vicina) was injurious at Ste. Annes to 

 mangels, beets and spinach. Complaints were received also from other parts of the 

 Province. 



The Hop Flea-Beetle {PsylUodes punctulata). Beets and mangels were 

 badly attacked by this insect in the early part of the season. It was the only flea- 

 beetle which occurred in very large numbers at Ste. Anne's.
