core. The surface injury is rather more common, the hirva eating 

 out just under the skin hirge irregular winding or blotch mines. 

 Larvae of this species apparently do not reach full development as 

 earlv in the fall as those of the codling moth, and manv find their 

 way into barrels where they continue to feed, occasionally doing 

 considerable damage. The larvae are small, flesh-colored cater- 

 pillars, measuring about three-eighths of an inch long and are 

 easily confounded with those of the codling moth. The moth is 

 about one-fourth inch long, generally of a rusty red color with 

 grayish markings. 



Treatment. — The insect is controlled by the same treatments as 

 recommended for the codling moth. 



GREEN FRUIT WORMS 



These insects sometimes do serious injury by eating into the 

 young apples. They also attack pears, plums, cherries, peaches 



and quinces. The full-grown cater- 

 pillars measure from an inch to 

 nearly an inch and a half in length. 

 They are green or yellowish-green in 

 color with various irregular markings 

 and stripes, the most prominent of 

 the latter being a narrow, cream-col- 

 ored one down the middle of the back 

 and a wider one along each side. 

 The caterpillars are most destructive 

 during May, soon after the fruit has 

 formed. They continue feeding until 

 about the middle of June. They feed 

 mostly at night, resting on the under- 

 sides of the leaves during the day.
