THE FRUIT-TREE LEAE-ROLLER. 93 



in Bulletin No. 9 of the Missouri State Fruit Experiment Station, 

 page 22 (1903), states that it was very destructive in 1901. In Bul- 

 letins Nos. 94, pages 9-11, and 114, page 7, of the Colorado Experi- 

 ment Station, Gillette again discusses this species. The most com- 

 plete account is by Stedman in Bulletin No. 71, Missouri Agricultural 

 Experiment Station. In the last edition (1909) of "Insects of New 

 Jersey," by Smith, it is included and mentioned as a very general 

 feeder throughout the State. An article by Herrick appeared in the 

 Rural New Yorker, March 2, 1912, page 263, in which it was discussed 

 as a "new pest of the apple in New York." The same writer, in 

 Bulletin 311 of the Cornell University Agricultural Experiment Sta- 

 tion, gives a full account of the species, as based on its occurrence 

 in New York State. 



The above includes all the important articles on this insect, so 

 far as the writer has been able to determine. 



DISTRIBUTION. 



The fruit-tree leaf-roller is generally distributed throughout the 

 United States. Stedman, in Bulletin No. 71 of the Missouri Experi- 

 ment Station, page 7, states that "this insect is found in damaging 

 numbers practically all over the United States from Maine to the 

 Gulf and westward to the Pacific coast and up as far as Oregon." 

 Packard, in 1870, gave its distribution as "Maine to Oregon and 

 Texas and Missouri." Holland gives its range as "Atlantic to 

 Pacific." So far as the writer has been able to determine from litera- 

 ture on hand, the species has been definitely recorded from New 

 York, New Jersey, Georgia, Missouri, Texas, Colorado, and California. 

 The writer reports it in New Mexico from Espanola, Santa Fe, and 

 Taos. It is also reported from Kiverside, N. Mex. In Colorado it 

 is recorded from Canon City, Vineland, Avondale, Cortez, Olathe, 

 Fort Collins, Brewster, Penrose, and Garden Park. The writer has 

 been unable to get a list of specific localities for other States. 



Although widely distributed throughout the United States, it 

 ranks as a pest at the present time in only a few localities in Colorado, 

 New Mexico, and New York, where conditions seem to have been 

 favorable, for some reason or other, for it to appear in enormous 

 numbers. 



FOOD PLANTS. 



The insect is a very general feeder and consequently has been 

 reported on a large number of plants. It appears at times in injuri- 

 ous numbers on apple, pear, plum, cherry, apricot, quince, peach, 

 rose, currant, raspberry, and gooseberry. It has also been recorded 

 feeding more or less on black walnut, horse-chestnut, soft maple, 

 hickory, oak, elm, wild cherry, ash, honey locust, box-elder, sassafras.
