 visit their vines. 



There are a few other insect enemies 

 which have been found in Canada prey- 

 ing upon the vine, but thus far they 



ters of fruit. Figure No. 6, c?, shews the 

 perfect beetle. Should the beetles be- 

 come numerous, so that they threaten 

 serious damage to the vines, the follow- 

 ing method of destroying them may be 

 adopted :

The Grape Vine Flea-Beetle is a little 

 greenish-blue, jumping fellow, that 

 should be carefully looked after when- 

 ever he makes his appearance, lest the 

 number should multiply so as to become 

 formidable. It feeds on the grape-vine 

 in both the larva and the beetle state. 

 Figure No. 6, a, shews the insect in the 

 larva state, and its manner of feeding 

 upon the leaves. At this time there is 

 no difficulty in gathering and destroy- 

 ing them, but in the beetle state they 

 are so active as to make it difficult to 

 catch them. If anything they are more 

 destructive in the beetle state, eating 

 into the bursting buds, and devouring 

 the entire embryo branch with its clus- 



Take two pieces of common cotton 

 sheeting, each being two yards long and 

 half as wide; fasten sticks across the 

 end of each piece to keep the cloth 

 open, and then drench with kerosene. 

 Give the sheets thus prepared to two 

 persons, each having hold of the rods 

 at opposite ends of the sheets. Then 

 let the persons pass one sheet on either 

 side of the vine, being careful to unite 

 the cloth around the base of the vine ; 

 then let a third person give the stake 

 to which the vine is attached a sharp 

 blow with a heavy stick. Such a blow 

 will, in nearly every case, jar the beetles 

 into the sheets, where the kerosene kills 

 them instantly. 



This process, after a little experience, 

 can be performed almost as rapidly as
