We, unfortunately, cannot prevent the Tortrix attack as we can 

 the Winter Sloth, and at present we know of no treatment which is 

 likely to destroy the eggs. 



We are liound to spray to kill the larva', and to be of a.iy help 

 this must be done before the lar\xe form those leaf-rolls or spin one 

 or two leaves together. Aljout mid April seems to lie tlie time when 

 we can catch most of tliese pests in the open, when tliey are small and 

 have done but little damage. Arsenate of lead has been found quite 

 successful, but two sprayings may be necessary, a second one in late 

 May for killing some of tlie last hatched caterpillars. 



Tlie ordinary spraying for AYinter Motli destroys the lairtrices at 

 the same time.
