40 THK EEPORT OP THE No. 36 



The Army Worm (HeJiophila imipunctata) which was so abundant this 

 year, has been dealt with by Mr. Baker in a separate paper. 



. Grasshoppers {Melanoplus atlanis, M. femur-rubrum, and Camnula pel- 

 lucida) were very abundant in a number of localities, especially in old pastures 

 and waste places. The new Kansas remedy was used with excellent results and 

 can be highly recommended. 'Results should not be looked for until two or 

 three days after the application. Beekeepers feared injury from this sweetened 

 poison, but field observations and experiments showed their fears were not justified. 



Garden and Greenhouse Insects. 



Millipedes. The last few years an increasing number of complaints of 

 injuries to garden plants from these have been sent in. It would be a boon to 

 learn of any simple and effective remedy. 



Tarnished Plant-Bug {Lygus pratensis). This insect is a great foe to 

 growers of dahlias as it punctures and destroys the blossom buds. A remedy is 

 badly needed. 



The Greenhouse Leaf-Tier {Phlyctmiia ferrugalis) . The caterpillar of 

 this small brown moth seems to be quite abundant in some greenhouses, and so 

 far as my experience goes, is most common on Chrysanthemums, the leaves of 

 which it ties together and feeds upon. 



Rose Leaf-Hopper (Typhlocyha rosq'). It is remarkable how many roses 

 have their foliage injured by this little pest. Tests with soluble sulphur — 2 lbs. 

 to 40 gals, water — and with lime-sulphur, 1.010 specific gravity, and also with 

 Black-leaf 40 and a small quantity of-soap, showed that any one of these would 

 control the pest if applied in May before the nymphs had become full grown. 



Forest and Shade Tree Insects. 



The Bronze Birch-Borer {Agrilus anxim) has during the last two seasons 

 destroyed many beautiful European 'Cut-leaved Birches in the neighbourhood of 

 Guelph. 



Cryptorhynchus lapatlii is in several parts of the Province doing much injury 

 to some species of swamp willows, and in some cases to some of the so-called 

 weeping willows on lawns. 



The European Fruit-Lecanium (Lecanium corni) has again become very 

 abundant, especially in a number of forest trees. It is, however, becoming heavily 

 parasitized. 



The Cottony Maple Scale (Pulvinaria vitis) was abundant on soft maples 

 at Guelph this autumn, but is heavily parasitized by Coccophagus lecanii Fitch. 



Addenda. 



Glassy Cutworm (IlaJena devastairir). Since writing the above, speci- 

 mens of this cut-worm have been sent me froui Grey County with the statement 

 that much damage is being done to winter wheat in fields that were not ploughed 

 early but late, or comparatively late. The larvae at this date (November) are 

 for the most part, about one inch long, though a few are an inch and a half. 



Prof. Caesar : I should like to hear from Prof. Crosby on the Tarnished Plant 

 Bug. and how to control it.
