60 FRUIT CULTURE. 



has been attacked falls prematurely, but usually 

 not until the worm has left. This is not always 

 so, and therefore this fallen fruit should always 

 be gathered. The moth is not attracted by 

 light, and hence cannot be caught to any extent 

 in this way. A more effectual remedy, as is 

 claimed by many Western orchardists, is the use

 trees at the time the fruit is first forming, in 

 a similar way to that hereafter described for the 

 canker-worm. It is earnestly to be hoped that 

 cautious experiments will indicate that this most 

 destructive pest may thus be controlled. 



The Apple Maggot is a footless, greenish-white 

 grub, one fifth of an inch long, with a pointed 

 head, but cut squarely off behind. It frequently 

 attacks apples that have been previously perfo- 

 rated by the codling moth. It is also frequently 

 very injurious to the fall varieties and those hav-

 No effectual remedy has been discovered. 



The Tent Caterpillar (Clisiocampa Ameri- 

 cana). This is a prevalent and conspicuous 

 enemy, but one easily met and destroyed. The 

 moth deposits its nest of 200 to 300 eggs in July, 

 near the ends of small branches, encircling them 

 as seen in Fig. 2. The eggs, being covered with
