19291 SERVICE AND REGULATORY ANNOUNCEMENTS 51 
The likelihood of carriage of infested fruits into the Cotton Belt States 
was obvious, and even prior to the taking of Federal quarantine action, the 
nature of this risk was brought to the attention of the appropriate officials 
of these States in communications on April 23, in which such officials were 
urged to have inspections made of all Florida fruits in markets or storage 
so that any infested shipments could be promptly destroyed. The Federal 
department assisted in this survey of other States to the extent of supplying 
some funds and personnel. 
This work resulted in the discovery of some 14 shipments of infested fruit — 
a good deal of it in carload lots — distributed to 10 localities in the following 
States : Arkansas, Georgia, Louisiana, North Carolina, and Texas. The infesta- 
tion in North Carolina was at Raleigh, and was based on the discovery of adult 
Hies which had emerged in a small grocery store from infested Florida fruit. 
Intensive clean-up operations were conducted at this point by the State offi- 
cials with Federal cooperation. Additional instances of infested fruit were 
reported from New York and Ohio. Especially extensive field surveys were 
undertaken in vicinities in which infested fruit was discovered, but their results 
were all negative and up to the time of the preparation of this report no ap- 
pearance of the fruit fly has been determined anywhere outside of the central 
area of Florida — a situation which greatly favors the eradication effort. 
QUARANTINE ACTION 
The State Plant Board of Florida promulgated on April 15 a State quarantine 
covering the then known area of infestation, together with a wide protective 
zone. Federal quarantine action restricting all movement of host fruits and 
vegetables from all parts of the State of Florida followed as soon as the 
required legal notices permitted. This quarantine, as issued April 26, became 
immediately effective as to all areas in that State which had been determined 
as infested, and was effective throughout the remainder of the State on May 1. 
As the surveys revealed new properties involved outside the known infested 
areas, the State regulations were amended to cover such additional districts. 
Modifications making additions of this kind were issued by the State plant 
board on April 27, May 4, May 13, May 28, June 8, and June IT. 
Both Federal and State regulations prohibited any movement whatever from 
groves within 1 mile of infested properties and placed especially severe restric- 
tions as to destination on fruit produced within 9 miles of infested properties 
In this manner the quarantine restrictions were automatically extended to new 
territory as rapidly as new infestations were discovered. 
The host fruits and vegetables listed in the Federal quarantine regulations 
as first issued included all wild and cultivated citrus and noncitrus fruits 
(except watermelons, pineapples, coconuts, and other nuts) and the following 
kinds of vegetables: Peppers of all kinds, gourds, pumpkins, squashes, toma- 
toes, beans of all kinds, and eggplants. Later, in August, strawberries, squashes, 
pumpkins, gourds, and all kinds of beans except Lima beans and broad beans 
were released from restriction, as the experimental work failed to reveal ade- 
quate evidence of their being susceptible to attack. 
DESTRUCTION OF FRUIT 
The destruction of host fruits on Infested properties and properties in the 
Immediate vicinity — that is, within 1 mile — constituted the first point of attack 
in the eradication effort. By the end of May 86336 acres had been cleaned 
and the equivalent of 563,067 boxes of citrus fruit destroyed. Within this 
area 77.702 acres had been covered by the crew-- the second time and were 
reported as haying been recleaned. During June 33,913 additional acres were 
cleaned the first time, r.L'.:;."! acres recleaned, and the equivalent of 15,433 
boxes of citrus fruit destroyed. 
SPRAYING 
Following the destruction of the Infested fruit, the aext step was to elimi- 
nate the Hies remaining in the district to prevent their migrating elsewhere 
To accomplish this the infested moves and Others within 1 mile thereof as to all 
points of infestation were promptly sprayed with a sweetened poison hait and 
these sprayings were repeated at frequent Intervals—If possible, every week, 
and. at the beginning in the heavily infested areas, even oftener.
