Suggestions for construction of plunging and growing beds
and their maintenance uider beetle-free conditions
in accordance with regulations of the white-
fringed beetle quarantine

Nursery stoc witx soil attached is eligible for certification

for movement from areas uder quarntine on account of the white-fringed

beetle provided it has been grown and maintained under beetle-free con-

dition8, as strcaiied in paragraph (b) of Regulation 5 of Quarantine

No, 72o

The following types of units are st-ggested as means of providing

for beetle-free condition and if properly maintained, should be effective

in preventing n, tra1 infestatio by the white-fringed beetle.

RAISED !,N-.V T BEDS

Beds or bentAe indoors or outside, which are at least 12, preferably

18 inches, above the grod and which are protected from infestation in

manner and by mthod atisfactory to an authorized inspector. Structures

of the type lAStrt' dn the accompanying plates are to be protected

against itestatio by approved oil or other barriers.

n~iACE 'VININ OR GR XING BES

A heeling-in ar -r growirg grounds enclosed within walls extend-

ing far nog er omn t, prevent larvae from passing under. ThIs

may require a wal as much as 24 inches in depth, The walls should be

of sufficien t above groud ';o permit the construction of oil or

other barriers on a ievei 12, preferably 18 inches, above the ground






The soil or other material contained or used therein should be treated

in approved maniier under the supervision and direction of an authorized

inspector. Such articles not immediately placed in the units should be

adequately protected from infestation,

During the a-ttJe adult beetle season, barriers constructed in

connection with pun4i and growing beds should be properly maintained,

and dd protective measures should be taken by estab-

lishments concerns to fully protect the approved units from infestation.

Vegetation should be kept down end calcium arsenate dust or other speci-

fied treatment applied to the atisfaction of an authorized inspector.



It will be necessary to protect the beds during the season of

adult activity by appr ed barrier. (See plates 3, 4, and 5)

Whenever practLcable, the oil barrier is recommended. The

heavy construction enales it to withstand jars or jolts which would

greatly decrease the efficiency of the all metal barrier.

Barriers should at all tines be maintained in a manner that will

assure their efficiency.

APPROVED OIL BARRIER

The type of barrier illustrated is
constructed of si inch pipes cut in
half. It is attached to the side wall
by means of strap iron cleats welded
to the pipe and braced from the bottom 1.
with iron braces, Pet cocks or set
screws are placed at strategi points.
in the bottom of the pipe to facilitate
cleaning and draLinrg0 The cc i is
made of 28 gauge sheet metal9 hinged
and built in section so that they may be ; cm ILeva
raised to facilitate inspection cleaning .""6po#e
and refilling. Oil barriers may be
constructed of 28 gauge sheet meta I or
such other durable metals as may be
approved by an authorized inspector.

APPROVED MA BARRI


This barrier ie constructed of 28 gauge sheet steel Its effic:?oncy is
in direct proportion to the smoothness of its surface. Care must be
exercised to keep the gaps between the tier- properly maintained _1d ti
prevent trash or litter from filling the spaces between the tie-.
