Codling-moths cannot always be controlled by spraying, especially in the 

 south-western section of Ontario, where a second brood appears later in the sea- 

 son. 



In addition to spraying, in this district, use bandages around the trees. Make 

 them from four to six inches wide, three or four inches thick, of any kind of 

 cloth. Old bags, sacks, carpets, coarse material of any kind will do. Bands of 

 straw and tow have been used with some success. During the first week in June 

 bind one around each tree three or four feet from the ground ; secure it either 

 with cord or small nails; take it off every twelve days, and carefully examine for 

 codling cocoons. These may be readily destroyed by crushing. Replace the 

 bands as before. 



Tent-caterpillars are controlled by burning the webs or nests in May ; by col- 

 lecting and destroying the clusters of eggs in fall and winter; by banding the 

 trees ; and by spraying the young caterpillars with Paris green. 



Canker-worms may be largely controlled by banding the trees in autumn and 

 early spring ; and by spraying with Paris green when the worms appear.
