INTRODUCTION

oducts Entering United 
This report covers the twenty-ninth year for which lists of pest interceptions 
liave been issued. The records summarized include 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 between Hawaii and Puerto Rico and the 
mainland. 
Determinations of collections made near the close of the preceding year are 
included with data for the current year. In addition to routine reports and deter- 
minations by the personnel of this Bureau, considerable information is supplied 
by State and customs officials. 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 of the Bureau of Plant Industry determine a 
large part of the more difficult plant-disease material. 
The scientific names of insects are checked by specialists in this Bureau and 
those of hosts and fungi by specialists in the Bureau of Plant Industry to make 
sure they conform to the appropriate international rules of nomenclature. 
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.
