LIST OF INTERCEPTED PLANT PESTS 
(List of pests recorded during the period July 1, 1932, to June 30, 1933, inclusive, 
as intercepted in, on, or with plants and plant products entering United States 
territory) 
FOREWORD 
This is the thirty-ninth paper of a series issued under various names and at 
more or less irregular intervals and listing intercepted plant pests. The present 
list covers the twentieth year of the period since the lists were started and includes 
intercepted plant pests for which determinations were received during the period 
specified, including those 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. 
The list is compiled in the Washington office from files maintained here. 
Much of the information summarized is furnished by inspectors and collaboiators 
(State and customs officials) of the Bureau of Plant Quarantine. A large part 
of the insect determinations are made by specialists of the Bureau of Entomology 
and many of the plant-disease 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, statements as to the origin 
of fruits and vegetables carried as ships' stores, as well as of plants used for 
decorative purposes and of plant materials carried by passengers, cannot always 
be verified, but every effort is made to give the origin of such plants and plant 
products as accurately as possible.

ludens) in grapefruit, mango, orange, and sweet lime from Mexico l ; dark fruit
