Control. 



The grape-blossom bud midge has not been found an easy 

 insect to control. The flies feed very little, if at all ; the eggs are 

 deposited in the interior of the bud, where maggots complete 

 their growth out of the reach of poisons. It has been suggested 

 that thorough cultivation of the soil might destroy a large 

 part of the larvae in their hibernating quarters, but the fact that 

 many well-cultivated vineyards are badly infested would in- 

 dicate that little protection can be expected from this method. 



Recent experiments conducted in New York show that '^ Black 

 Leaf " tobacco extract, 1 gallon in 50 gallons of water, is of con- 

 siderable value in deterring the flies from depositing eggs, 

 and thus lessens the number of injured buds. The first ap- 

 plication should be made just as the buds of the early vari- 

 eties begin to show an opening at the apex between the tips 

 of the petals, and the second should follow in about one week.

The Grape (-urculio 



Craponius incequalis Say 



While widely distributed throughout the United States east 

 of the Rocky Mountains the grape curculio has been most 

 destructive in Missouri, Illinois, Ohio, Kentucky, West Vir- 

 ginia and North Carolina. In West Virginia losses from this 

 cause of from 50 to 75 per cent of the crop are not uncommon. 

 It is a native American insect which fed originally on the various 

 species of wild grapes. 



The small, inconspicuous, brownish snout-beetles, one 

 tenth of an inch or less in length, emerge from hibernation and
