suitable shelter, and spins its cocoon. Here it may remain until the 

 next spring, but in the Central and Southern states there is a second 

 brood. The larvae of the 

 latter often feed merely on 

 the surface of the apple in- 

 stead of boring into it. 



Control consists in spray- 

 ing with arsenate of lead. 

 The most important point is 

 to apply the material just 

 after the blossoms fall, while 

 the calyx cup is still open, 

 and to direct the spray so 

 that the poison will lodge in 

 the blossom end of the up- 

 turned apples. A second 

 spraying about three weeks 

 later, at the time when the 

 worms are just hatching, will augment the value of the first, because 

 the larvae feed a little on the leaf before going to the apple. For the 



second brood in midsummer 

 arsenate of lead is used, as 

 for the fu"st brood. 



The Lesser Apple Worm 



(Laspeyresia {Enarmonia) 



prunivora Walsh) 

 Injury to the fruit of ap- 

 ples by the lesser apple worm 

 is often confused with that 

 of the codling moth, but is 

 distinct on careful examina- 

 tion. Early in the season 

 the injury is apt to take the 

 form of small cavities eaten
