Excerpt from List of Intercepted Plant Pests: List of Pests Recorded During the Period July 1, 1931, to June 30, 1932, Inclusive, as Intercepted In, On, or With Plants and Plant Products Entering United States Territory

This is the thirty-eighth paper of aseries issued under various names and at more or less irregular intervals and listing intercepted plant pests. The present list covers the nineteenth 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 collaborators (state and customs o leials) of the Plant Quarantine and Control Administration, here after to be known as the Bureau of Plant Quarantine. A large part of the insect determinations are made by specialists of the Bureau of Entomology and 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, numbering some thousands, are omitted from the list.
