THE OBLIQUE-BANDED LEAFROLLER 



Archips rosaceana Harris^ 

 By E. DwiGiiT Sanderson and Alma Drayee Jackson 



In July, 1909, our attention was called to a case of very serious 

 injury caused by the Oblique-banded Leafroller in a large rose house 

 at Madbury, N. H. This is one of the largest rose conservatories in 

 the country, the two houses having a total length of nearly one-half 

 a mile and covering three acres. The roses on one or two benches had 

 been entirely defoliated for over 200 feet as shown in Plate 15. Brief 

 reference to entomological literature gave practically no information 

 of value concerning the pest, so that an investigation was commenced 

 at once. Mrs. Jackson kindly took entire charge of the rearing work 

 and is responsible for the account of it, while the senior author is 

 responsible for the rest of the present article. 



History 



This insect is an interesting example of one of our best known and 

 much be-written species about which there seems to be but little infor- 

 mation. Among the sixty-eight references given in the bibliography, 

 less than a dozen give any very original information of any impor- 

 tance. The great bulk of the literature is mere compilation and 

 quotation from Harris, the original describer. Coquillett seems to 

 have made the most observations upon the species, but not until 1903 

 were the eggs briefly mentioned by Hart, and no one seems to have 

 observed the stage which passes the winter. The insect has been a 

 common one thruout the United States and, as the bibliography shows, 

 has been noted for over half a century wherever entomologists have 

 been located. 



Injury 



Serious injury by it has, however, been only occasionally reported. 

 In 1894 Fletcher reported injury to the foliage and young fruit 

 of pears in Ontario. In 1895 Piper noted considerable injury to 

 prunes in Washington. In 1896 Lintner recorded serious injury to 

 apple foliage and by the larvfe gnawing into young apples in eastern 

 and central New York. The same year Lugger reported that Russian 

 apples are sometimes defoliated by the caterpillars in Minnesota. No 

 very serious injury to roses was noted until Chittenden in 1903 men- 

 tioned a case in which roses received from Ohio at Libonia, Pa., in 



^Moths were determined for us by the courtesy of Prof. C. H. Fernald.
