LIST OF INTERCEPTED PLANT PESTS, 1939 
<List of Pests Recorded During the Period July 1, 1938, to June 30, 1939, Inclu- 
sive, as Intercepted in, on, or with Plants and Plant Products Entering United 
States Territory.) 
INTRODUCTION 
The period covered by this report is the twenty-sixth year for which lists of 
interceptions have been issued. The detailed table showing pest interceptions 
from various countries is limited to species of particular interest or importance. 
Brief summaries indicate some of the commoner species noted during the course 
of inspection. Following the introduction are notes calling attention to some of 
the more interesting findings. 
The records summarized in this report cover some of the pests intercepted in, 
on, or with plants and plant products (1) imported, (2) offered for but refused 
entry, (3) held as ships' stores, etc., and hence not imported through customs, 
(4) offered for entry for immediate export or for immediate transportation and 
exportation in bond, and (5) in domestic shipments reaching the mainland from 
Hawaii and Puerto Rico. 
Collections made late in the year are often included in the report for the follow- 
ing year, especially if not determined immediately. The data on which this paper 
is based are on file in Washington, D. C. In addition to routine reports and 
determinations by the personnel of this Bureau, State and customs officials furnish 
considerable information. Staffs of specialists maintained by the States of 
California and Florida and the Territory of Hawaii determine most of the inter- 
ceptions made there, and specialists in the Bureau of Plant Industry determine a 
large part of the more difficult plant disease material. 
The alleged origin of plant materials cannot be verified in all cases. Obviously 
doubtful items are either omitted or the origin is listed as unknown.
