112 PLANT QUARANTINE AND CONTROL ADMINISTRATION [April-June, 
apparent and lie has urged all department inspectors to give wide publicity 
to tlie need for the practice and if possible to secure its general adoption. 
The reports of finding infested Florida citrus fruit received from other 
States mention only the finding and destruction of such fruit, Doctor Marlatt 
says, and make no mention of any clean-up of storage places and premises. 
Doctor Marlatt is anxious that fruit handlers, dealers, and the public gener- 
ally realize the necessity of thoroughly cleaning and disinfecting cars, storage 
rooms in refrigerating plants, boxes and other containers, and the immediate 
surroundings, in shops or other places where such fruit has been kept. 
Risks of spreading the fruit fly and other pests can be very much reduced, 
Doctor Marlatt says, by making sure that all boxes and other containers are 
thoroughly cleaned, followed by very careful sweeping up of all dirt, dust,- 
and trash which may be beneath the boxes. Such sweepings should be care- 
fully taken up and burned. 
Applications of oil, boiling water, or steam to all places likely to be infested 
with the larvae of the fruit fly are advisable. 
Re Mediterranean Fruit Fly — Orchard and Packing-House 
Sanitation Urged for All Fruit Sections 
P. Q. C. A.— 235. June 5, 1929. 
The Mediterranean fruit-fly situation in Florida has emphasized the great 
desirablity in all fruit sections, of clean-up of fallen fruit and the destruction 
under safe means of fruit dumps and rejects, and this is particularly true 
of all commercial orchards and of packing houses. It is unnecessary to 
point out the increase of risk from such dumps and rejects and fallen fruit in 
orchards not only as to the Mediterranean fruit fly, but as to other common 
insect pests of the fruits. Such clean-up of orchards and safe disposition of 
packing-house culls is probably seldom made, but the necessity therefor is 
clearly apparent and you are urged to give wide publicity to this idea and, 
if possible, secure its general adoption. 
This is certainly a time when an accounting should be taken of methods 
of handling crops to safeguard against pests, but this is of special importance 
in relation to the present uncertainty as to the extent of spread of the Medi- 
terranean fruit fly.

MEDITERRANEAN FRUIT-FLY QUARANTINE REVISED TO PROHIBIT RESHIPMENTS 
OF FL0RD3A FRUITS AND VEGETABLES FROM NORTHEASTERN STATES TO 
SOUTH AND WEST 
[Press notice] 
* June, S, 1929. 
The Secretary of Agriculture announced to-day a revision of the Mediterra- 
nean fruit-fly quarantine effective immediately. The primary purpose of the 
revision is to provide for the regulations, issued therewith, forbidding the re- 
shipment of Florida host fruits and vegetables from Northern and North- 
eastern States into the territory of the South and West into which direct 
shipment from Florida is already prohibited. The revision is intended also to 
furnish the basis for the prompt handling of any infestations which may later 
be determined in other States. The Secretary points out that the regulations 
issued with this revision of the quarantine are merely supplemental to the 
regulations, and amendments thereto hitherto promulgated under the original 
edition of the quarantine, which latter regulations remain in full force and 
effect. 
Under the supplemental regulations issued with the revised quarantine, host 
fruits and vegetables which have been produced in and moved from the State 
of Florida shall not thereafter be reshipped or otherwise transported into the 
States of Alabama, Arizona, Arkansas, California, Georgia, Idaho, Louisiana, 
Mississippi, Nevada, New Mexico, North Carolina, Oklahoma, Oregon, South 
Carolina, Tennessee, Texas, Utah, or Washington, or into the Territory of Porto 
Rico. It is further provided that host fruits and vegetables which have been 
produced in a " protective zone " — i. e., the zones immediately surrounding 
infested zones — and moved into the area northeast of and including Potomac 
Yards, Va., the District of Columbia, and the States of Maryland and Pennsyl- 
vania, shall not thereafter be reshipped or otherwise transported to points in the- 
United States outside the said northeastern area.
