THE REPORT OF THE 



No. 36 



Grape ant> Small Fruit Insects. 



The Grape Leaf Hopper (Typhlocyba comes). There was a serious out- 

 break of the grape leaf hopper in the Niagara district, particularly in the sertion 

 between Grimsby and the Niagara river. During late summer and autumn badly 

 infested vineyards were conspicuous from a distance on account of the brownish, 

 or, as some growers put it, "rusty" condition of the foliage. The severe injury to 

 the leaves naturally affected both the size and quality of the fruit. 



Agawam grapes. — A. Typical bunch from sprayed vines. 

 B. Typical hunch from hopper-infested vines. 



As a general rule, the leaf hopper is only troublesome in the vicinity of wood- 

 lots and waste land, where the fallen leaves, long grass, weeds, etc. afford the 

 insect favorable hibernating quarters, but this year it was abundant and injurious 

 even in vineyards with comparatively clean surroundings. 



Immense numbers of hoppers went into hibernation in the fall and no doubt, 

 if the winter is favorable for the insect, there will be another outbreak next year. 



Rose Chafer (Macrodactylus suhspinosus) . A severe outbreak of the rose 

 chafer occurred at Fenwick, and in the affected section graperies, which were not 

 sprayed, ■ were completely or almost completely stripped clean of blossoms and 

 newly-set fruit. The chafers were present in the vineyards for some three weeks. 



There was also a small outbreak of the chafer near Beamsville. 



Strawberky Leaf Beetle (Paria canella). Strawberry leaf beetles occurred 

 in exceptionally large numbers last spring in the Vineland-Jqrdan district, and 

 attacked and riddled the foliage of. strawberries. They also attacked. the opening 

 buds of raspberries and in some cases destroyed them. _The larvae were commonly
