refused entry. Immediately upon confirmation by specialists of t he- 
identity of the nematodes, permits authorizing the importation of 
potatoes from Spain and the Canary Islands were -suspended. 
TRANSIT INSPECTION 
Transit inspection of domestic mail was coordinated with the inspec- 
tion of foreign mail during the year. As a result both activities were 
broadened and strengthened. The new arrangement permits more 
effective utilization of manpower. It permits the performance of 
foreign mail inspection at several points formerly manned only by 
transit inspectors. Foreign and domestic mail inspection was resumed 
after a lapse of several years at Omaha, Nebr., an important center 
for both of these activities. 
During the year, more than 1,166.545 shipments were examined 
at the 18 stations where transit inspection was conducted. Inspectors 
found 1,169 shipments that were moving contrary to the major Federal 
or comparable State quarantines. Another 3,148 shipments failed 
to comply with District of Columbia plant regulations or quarantine 
or nursery inspection requirements of the States. 
Foreign mail inspected upon arrival in the United States was found 
to contain such destructive pests as the golden nematode, the olive 
fly, citrus canker, and another disease of citrus, Phoma citricarpa. 
Hundreds of packages of shamrocks from Ireland intercepted in the 
mails were fumigated to kill cysts of the golden nematode. 
JAPANESE BEETLE 
Trap-Scouting Detects Beetle Spread 
Surveys to detect spread of the Japanese beetle continued with traps 
set in 1,700 communities in 36 States outside the infested area. One 
beetle was taken for a first-record collection in Los Angeles, Calif. 
The site at which this beetle was collected and 5 acres surrounding it 
were treated with chlordane shortly after the discovery. An estab- 
lished infestation in South Bend, Ind., was discovered. Foliage was 
sprayed with DDT and soil surface treatments with DDT or chlor- 
dane were applied to 184 acres in this locality. In addition, State 
quarantine regulations were issued covering the South Bend infesta- 
tion. There were other significant beetle collections in New York and 
in a number of Midwestern and Southern States adjacent to regulated 
areas. 
Regulated Area Extended to Include Established Infestations 
Following the 1951 survey season, regulated areas were extended, 
effective August 14. 1051, in four of the quarantined States and North 
Carolina was placed under Federal quarantine for the first time. Also, 
effective June 4, 1952, further amendments added additional territory 
to the regulated areas in New York, Ohio, Virginia, and West Vir- 
ginia. They also established a procedure for restricting the move- 
ment of regulated articles to an isolated regulated area when it has 
been determined that such movement presents a hazard of spreading 
Japanese beetle infestation.
