at the rate of two tablespoonfuls in a gallon of water. This is 

 the best way to handle all plant lice on the ends of branches upon 

 trees not too high for such treatment. 



Cherry-leaf Beetle. Ordinarily, attacks on the part of this 

 insect (Galerucella cavicolis Lee.) are confined to wild cherry, but 

 early in the summer these beetles freely attack cherries in orchards. 



Description and Life History. The adults are small red beetles 

 which lay their eggs in the spring in soil close to the trees, but 

 they may be placed on the bark. About three weeks are required 

 for hatching. The grubs are born with black head. When full 

 grown they are about one-third of an inch long. The pupae are 

 found in the ground during the latter part of July (Fig. 153). 



Remedial Measures. Use arsenate of lead spray or nicotine 

 sulfate.

 sects which attack the cherry. See page references to those de-

The Fig Eater or June Bug. For a description of this insect, see

up and destroyed.
