102 INSECTS INFESTING THE APPLE TREE. 



They feed on the foliage at night and hide themselves in the 

 ground and dark places in the day time ; recent reports state 

 that in some sections they have damaged the foliage of young 

 trees. 



Description. — Length, four and one quarter lines ; form, 

 elongate ovate, narrowing toward the head ; color, reddish- 

 chestnut, but grows darker with age ; antennte, lamellate. 



The larva of this species I have not found, but it probably 

 lives in the ground, feeding upon the roots of grasses, etc., near 

 the roots of the trees on which the perfect insect feeds. 



Remedy. — Use No. 38. 



CHAPTER LI. 



The Codlin Moth, or Apple Worm. (Cal.) 



( Ca rpocapsa pomoneUa . — Linn. ) 



Order. Lepidoptera ; Family, Tortricid.e. 



[Living in apples, etc., a whitish, sixteen-legged worm.] 

 It is generally conceded that this insect was imported into 

 this State in shipments of apples received from states east of 

 the Rocky Mountains, and placed on exhibition at the State 

 Fair in or about the year 1873. Its first appearance in an 

 orchard in the vicinity of Sacramento was in the Spring of

 at the present time infesting orchards in thirt3'-four counties. 

 The moth belongs to the family Tortricidtel, and is known 

 to naturalists as Carpocapsa pomonella (the codlin or apple 

 moth). It passes the Winter in the larva state, and in some 

 instances in the chrysalis form. The larva can be found 

 hibernating under the loose bark, in crotches or indents, or in 

 cracks in the bark of the trees infested the previous year, or in 

 the crevices of wood, or woodwork of rooms, or places where 

 fruit infested by the larva was stored or packed, and in empty 

 packages in which fruit was shipped or gathered. It is often 

 found hibernating on bark of trees, from one to six inches 

 below the surface of the ground, especially if the tree has
