This bulletin presents the results of studies of this species carried on in 1920 and 1921 at the field station maintained at Wallingford, Conn., for the study of fruit insects, by the Bureau of Entomology, in cooperation with the Con- necticut Agricultural Experiment Station at New HISTORICAL The native home of the bud moth seems to be Europe, where it has been mentioned in entomological literature since 1776, when it was described by Denis and Schiffermtiller (l)2 under the name Tortrix ocellana. The bud moth was presumably introduced into the United States with the early importations of apple and other nursery stock, but no mention seems to have been made of it until 1841, when Harris (3) gave a short account of it under the name Penthina During the next 40 years only occasional short mention of the pest was made. 1 The work of the Wallingford station has been under the direction of Dr. A. L. Qpaintance. The writer was assisted In 1920 by C. H. Alden and in 1921 by H. M. Tietz. The writer wishes also to thank Carl Helnrlch, of the Bureau of Entomology, for asslst- ance in the preparation of t
