FLEA-BEETLES INJURING THE FOLIAGE 



265 



blue insects, one eighth to one fifth of an inch long, and rather broad. 

 They are able to fly readily and jump quickly. 



Eggs are soon laid, and the larvae feed on the surface of the leaves, 

 leaving the veins untouched. A pupal stage is passed in the ground, 

 and there is a sec- 

 ond generation in 

 midsummer, but 

 damage by this later 

 brood is not par- 

 ticularly noticeable 

 because the foliage 

 is relatively more 

 abundant. 



To control, spray 

 with 4 pounds of 

 arsenate of lead 

 and 1 gallon of 

 cheap molasses to 

 50 gallons of water. 

 Apply the spray 

 early, at the first 

 appearance of the 

 beetles, before they have opportunity to destroy the buds. Where 

 only a few vines are concerned, the adults may be jarred off onto 

 sheets, if the work is done early in the m.orning before the beetles
