a piece of cotton cloth b}' which it is fastened to the tree making an 

 inverted funnel. 



Whatever apparatus is used care should be taken to stop any 

 holes made by irregularities of the bark or trunk. Cotton batting, 

 straw or rags can be used for this purpose. When sticky substances 

 are applied they should be renewed occasionally during the time the 

 moths ascend or the larvaj descend. This involves considerable 

 time but pays. 



Fall plowing has been recommended to expose the cocoons to the 

 weather and birds. Hogs are said to root up the chrysalids and eat 

 them. Hens eat the larvae. 



Canker worms are preyed upon by a species of mite, by ichneu- 

 mons, a tachina fly, a wasp, a soldier bug, and by several species 

 of pedaceous beetles, which help hold them in check. Insect eating 

 birds devour them. 



THE EYE-SPOTTED BUD-MOTH. 



Tmetocera ocellana, (Schifl). 



Attention was called last spring to an insect doing injur}- to the 

 terminal buds of apple trees in the college orchard, and about a 

 hundred larvae were taken from a single tree, part of which were 

 allowed to transform and proved to be the species named above. 

 We also noticed in the orchard of Mrs. A. A. Sutton of Orono 

 several 3oung trees so badly affected by this insect that nearly all 

 the terminal clusters had turned brown. If as plentiful else^vhere it 

 must do considerable damage. It does not confine its depredations 

 to the leaf clusters but will attack the flower clusters and even the 

 newly-formed Iruit; also the small twigs from which the blossoms 

 come, tunneling them down the center, causing their death. It 

 does not confine its mischief to the apple, but attacks also the 

 cherry and plum. 



Perfect inaect — A moth of an ash gray color which expands half 

 an inch. Fore wings banded across the middle with whitish gray, 



^^A^^„^^ and each wing bearing two small eye-like spots, one 



^■HE^ Jiear the tip, composed of four little black marks on 



a light brown ground, the other formed of three mi- 



-■ ^^^^ ^-^ nute black spots arranged in a triangle and located 



near the hind angle. Hind wings dusky brown. The moth natural 



size is shown in Fig. 21.
