A New Apple Pest. 645 



fii*e ; and any active boy could go over a large number of trees in a 

 very few days. The little sticks, as also the solution, could be carried 

 in an old billy-can in front of the operator. 



As the grubs of this moth, if not destroyed, remain a long time in 

 the trees (how long has not, I believe, been well ascertained) it will 

 be all the more necessary to tackle them at once, as prevention is, 

 after all, better than the cure. 



The use of a lamp, such a one as is figured [in the book referred 

 to], might also be tried with advantage in capturing the moths, both 

 males and females, which, as a rule, are not numerous. 



The forcing of steam into the holes made by this and other boring 

 insects would, I feel certain, be of great benefit, and as the moth 

 itself is not of a small size, and by its colour is somewhat conspicuous, 

 there should not be much trouble in combating the ravages of this 

 pest. 



Old and abandoned orchards are fertile sources of infection, and 

 should be carefully watched by growers and by all interested in fruit- 

 growing as a profitable industry."
