and killed in the traps, and therefore reduction of the future beetle population 
will be in direct proportion to the efficiency of the method. 
Similar trapping will be carried out by the Plant Quarantine and Control 
Administration at a number of other isolated points. 4 For Maryland these 
include Baltimore, Cambridge City, Frederick, and Hagerstown — a single beetle 
was found at Hagerstown and two at Frederick. Additional outlying points 
are Marysville and Say re, Pa., Hartford and New London, Conn., and Spring- 
field, Mass. 
These traps have been developed as a result of experimentation extending 
over a number of years conducted in the heavily infested Japanese-beetle areas 
in New Jersey. In such areas in the period of beetle abundance it is possible 
to collect a quart or more of beetles in a single night in one trap, and with 
many traps in an orchard beetles may be collected in enormous numbers. 
To have any great benefit in effectively controlling the pest in areas of heavy 
infestation it would be necessary for all property owners to place traps abun- 
dantly, otherwise the few ind vidual property owners utilizing the traps would 
by the same means, attract the beetles from adjacent properties and any 
advantage might thus be more than offset by newcomers. As already indicated, 
in outlying points such as those mentioned, this objection does not adhere and 
every beetle killed is a reduction of potential increase in population during 
the breed. ng season of June, July, and August. The bait used in these traps 
is geraniol, a manufactured product which is a very powerful attractant to 
the adult Japanese beetle. So far as known, this bait is not attractive to 
other insects. The public is urged to respect these traps and give them the 
full opportunity to do their job of control work. 
MEDITERRANEAN FRUIT FLY QUARANTINE (No. 68) 
MEDITERRANEAN FRUIT FLY DISCOVERED IN FLORIDA 
April 15, 1929. 
The Mediterranean fruit fly, an extremely destructive pest of fruits and 
vegetables, has been discovered in Orange County, Fla., at points In and adjacent 
to Orlando, according to an announcement issued by the Department of Agri- 
culture to-day. 
Immediately on the confirmation of the discovery, Doctor Marlatt, chief of 
the Plant Quarantine and control administration of the department, went to 
Florida and is working in full cooperation with the State officials. 
Growers and packers are cooperating with the State officials and since the 
discovery no dangerous fruit or products likely to carry the pest have been 
allowed to move from infested orchards or packing houses. Steps have ai 
been taken to clean up all infested groves and packing plants. 
The Florida State Plant Board is to-day meeting at Gainesville. Fla., and it 
is antic pa ted that this meeting will be followed by an announcement of an 
eradication program. 
The Secretary of Agriculture to-day announced a public hearing to be held 
at it; a. in.. April 22, before the Plant Quarantine and Control Administration 
and Federal Plant Quarantine Board ;it ITli!) New York Avenue. NW.. Washing- 
ton, 1>. C, t«> consider the advisab "lily of quarantining the State of Florida on 
account of and of restricting or prohibiting the movem< aches, 
plums, grapefruit, i a d all other host- of this insect from that state or 
from any district therein. 
The Mediterranean fruit fly Is the most widely distributed and dangerous 
fruit fly known and OCCUra in many places In the tropics and suhtropics o\' the 
New and Old World. Heretofore it lias not gained entry into the United States. 
it attacks a large variety of fruits, including melons, and a restricted Dumber 
of vegetables.
