 curled up in them as caterpillars until spring opens, when 

 they transform, through the pupa, to the 

 moth (Fig. 243), thus completing their 

 yearly life-cycle. 



No panacea for the codling-moth has 

 yet been found, but by thorough work 

 with a Paris green spray one can often 

 s'ave at least 75 per cent, of the apples 

 that would otherwise be ruined by the 

 worms. Where two or more broods of the 

 insect occur during the season, as in Kan- 

 sas, Nebraska, Oregon, New Mexico, and 

 neighboring localities in the West, and 

 in the South, the poison spray is not so 

 effective, for, although 75 per cent, of the
