and the Seed Corn maggot (C fusciceps). The Carrot Rust Fly {Psila 

 rosae) was the cause of much injury to carrots. 



The Beet-Leaf Miner {Chortophila vicina) was very abundant on 

 mangels, beets and spinach. Complaints were received from various 

 parts of the province where this insect was reported as causing much injury. 



The Hop Flea Beetle (Psylliodes punctulata) was injurious to beets 

 and mangels at Ste. Annes. The insect causes great loss to hop growers 

 in the west where it also attacks several other crops. This is the first 

 record of injury by this insect in the province of Quebec. 



The Parsnip Web Worm (Depressaria heracliana) gained prominence 

 as a pest last season owing to the fact that parsnips were grown for seed 

 here for the first time. The caterpillar is greenish yellow above and lighter 

 beneath, and bears numerous setigerous black spots. It usually enters the 

 developing flower heads where it constructs a nest and feeds on the flower 

 buds, seeds and young leaves. It has been present on wild parsnips in the 

 neighborhood of Ste. Annes for years but it did not before invade the 

 cultivated fields, owing to the fact that no attempt had previously been 

 made to produce parsnip seed. 



Insects Attacking Fruit 



The Bud Moth (Eucosma ocellana) has been for several years one of 

 the most injurious apple tree insects in the province. It was again abundant 

 last season. Experiments were carried on last year on the control of this 

 insect and the results showed that the best two-spray combination was 

 the second and third sprays of the ordinary spray calendar, i.e., a spray 

 applied three days before the opening of the petals, and one shortly after 

 the petals fall. 



An interesting example of the value of parasitic insects was observed 

 last season when the Minute Chalcid Fly (Pentarthron minutiim) practically 

 controlled the Plum Slug {Eriocampoides limacina) . This pest was quite 

 injurious during 1913 and 1914, and the number of eggs laid in the spring 

 gave promise of a similar destructiveness in 1915. The eggs, however, 

 were so effectively parasitised that it was not necessary to spray specially 

 for this slug. 



Other insects very abundant in some neighbouring orchards last year 

 were the Apple Maggot, the Cigar Case Bearer, and the BufTalo Tree 

 Hopper. 



The most important pests of small fruit were the Currant Saw Fly, 

 the Raspberry Saw Fly and the imported Currant Borer.
