DUTCH ELM DISEASE QUARANTINE
NOTICE OF QUARANTINE NO. 70
Provision was originally i:inide i thiis qu;rlalntinet' for tihe importation from
Europe of elm veneer logs if free froin bark and wood-infesting insects, and
with a prescribed hot-water treatment required before release. It has been
found, however, that the complete removal of all vestiges of bark, which alone
would eliminate both adult and larval stages of the scolytid beetles known to
be instrumental in spreading the Dutch elm disease, has not been effectively
accomplished in the majority of shipments presented for entry under this pro-
vision. Both nalult and larval stages ,,41f scolytils hl:ive been found in bark
remnants on these elmi burl logs. even where bark removal evidently had been
attempted before shipment. Under these circumsiitaices it seems hopeless to
expect a bark nrtmoval complete enouizh to eliminate these carrier insects from
the deep crevices of gnarled and twisted hurls, and since the presence of such
insects in any stage, in any number, at any Iport. is regarded as involving a
definite danger of further introduction of the D)utch telii disease, this quaran-
tine has been revised to exclude all elm veneer l,,ogs froin Euroipeain sources.
