THE EEPOET OF THE 



No. 36 



Bud Moth. This small insect was very abundant on the Island of Montreal 

 in May and June. In one instance more than 100 specimens were obtained from 

 a snxall five-year-old apple tree. Pupation occurred about June 15th, and adults 

 appeared on July 9th. 



Buffalo Tree-hopper. This bug was quite abundant, and many apple 

 branches were observed to be badly wounded. An interesting feature of the occur- 

 rence of the nymphs was their abundance on clover, so that the presence of clover 

 fields must be taken into consideration in devising methods of control. 



Plum Cueculio (Fig. 31). This insect is not destructive at Macdonald Col- 

 lege, though in near-by orchards there was evidence of considerable injury, especi- 

 ally to plums. 



Oyster-shell Scale. This scale insect is perhaps the most abundant insect 

 in Quebec orchards, and does a great amount of damage, especially in neglected 

 orchards.

Apple Plaxt Louse. Aphis mail was abundant on the young trees, and 

 caused considerable damage. 



Clover-root Borer. The roots of old red clover plants in the sod of the 

 plum orchard at Macdonald College were observed to contain many larvae of the 

 Clover-root Borer. 



Clover-leaf Midge (Fig. 32). This insect was quite abundant on leaves of 

 white clover at the College. 



Striped Cucumber Beetle. This pest was destructive to squashes. 



Asparagus Beetle. The 12 spotted species were abundant, but very few of 

 the asparagi were observed. 



Turnip Flea-beetle. This insect was abundant but did not appear until the 

 plants had got a good start, so that the damage was inconsiderable. 



Easpberry-cane Borer. Considerable wilting of canes occurred in July 

 owing to punctures made by this insect. 



Currant Saw-fly (Fig. 34.) Large numbers of the larvae of this insect were 

 observed on currant hushes during June and July. Pupation began about June 

 10th, and adults began to appear on the 22nd. 



Currant Aphis. This plant louse was quite abundant, and caused consider- 

 able damage to the leaves.
