beetles had largely disappeared of their own accord. As I was interested, I 

 visited the orchard and examined the ground around the trunks of several small 

 sprayed cherry trees and in each case found dead beetles. It looked to me very 

 much as though the spray had been at least fairly effective. 



Pear and Cherry Slug {Eriocampoides limacina). Though not quite so 

 conspicuous as usual, the work of this pest was easily visible in almost every 

 district. Young cherry trees were usually worst attacked; pears suffered but little. 



Grapes and Bush Fruits Insects. 



Grapevine Leaf-hopper {Typhlocijba comes). This leaf -hopper was present 

 in most vineyards but was not so destructive as last year. 



Currant Stem-girdler {Janus integer). Two years ago I reared this saw-fly 

 from currant twigs sent me from Lambton County. In June of this year I found 

 its fresh work at Fruitland. A considerable number of currant twi^s had been

girdled but not a sufficient number to cause any alarm. The owner of the planta- 

 tion had never seen the injury before and was anxious to discover the cause. 



Imported Currant Borer (Aegeria tipuliformis) . In abnost every currant 

 plantation a very large number of canes are attacked by this insect 



The Grapevine Flea-beetle (Haltica chalyyhea). Several vineyards in the 

 Niagara District were somewhat severely attacked by these beetles. The larvge 

 could be easily found on wild grape leaves in June. 



Raspberry Eoot-borer (Betnbecia marginata). Old raspberry plantations in 

 the Niagara District are very badly infested by this borer.
