Bur. Ent. & P. Q. Issued August 1936 United States Department of Agriculture BUREAU OF ENTOMOLOGY AND PLANT QUARANTINE SERVICE AND REGULATORY ANNOUNCEMENTS LIST OF INTERCEPTED PLANT PESTS, 1935 (List of Pests Recorded During the Period July 1, 1934, to June 30, 1935, Inclusive, as Intercepted in, on, or with Plants and Plant Products Entering United States Territory) INTRODUCTION This is the forty-first paper of a series issued under various names at more or less irregular intervals listing intercepted plant pests. The present list covers the twenty-second year of the period since the lists were started and includes intercepted plant pests for which determinations were received and indexed during the period specified. The sources from which the data were derived and the manner of preparation are discussed in previous lists. Most of the insect determinations were made by specialists of the Bureau and many of the plant-disease and host determinations by specialists of the Bureau of Plant Industry. The States of California and Florida and the Territory of Hawaii maintain their own staffs of specialists and make many of their own determinations. Frequently the intercepted material is in a stage that is not determinable or is too badly damaged or is inadequate for determination. Many times the only organisms recognized are innocuous. Such interceptions, num- bering some thousands, are omitted from the list. As pointed out in previous lists of interceptions, statement as to the origin of fruits and vegetables carried as ships' stores, as well as of plants used for decora- tive purposes and of plant material carried by passengers, cannot always be veri- fied, but every effort is made to give the origin of such plants and plant products as accurately as possible.
