JAPANESE BEETLE 
Quarantine ictivitiefl Expanded 
Trap Bcouting to detect incipient infestations of the Japanese beetle 
le the regulated area was carried on in 1,410 localities in l_ States. 
Beetles were trapped in 204 Localities in L6 States. With the excep- 
tion of tlic continued occurrence of a small Dumber of beetles at St. 
Louis, Mo., mi beetles were found west of the Mississippi River 
ew infestations were found south of North Carolina and Ken- 
tucky. Many Bureau field stations, United States military establish- 
ments, and State agencies cooperated in the extensive survey. 
As a means of controlling the significant infestations discovered, 
soil treatments were applied on more than 900 acres in 27 Localities 
scattered in 9 States. Foliage was sprayed to kill the adult beetles at 
83 location- in 1 1 States. 
A public hearing to consider either the revocat ion of the quarantine 
or its extension to include seven additional States was held at Wash- 
ington, I). C, on March 30, 1951. Based on the testimony at the 
hearing, a notice was published in the Federal Register on Jul 
announcing the Department's intention to continue the quarantine, to 
amend the quarantine to include the State of North Carolina, to place 
extensive sections of North Carolina under regulation, and to extend 
the current regulated areas in New York. Ohio, Pennsylvania, and 
West Virginia to include all significant infestations discovered in 
nonregulated sections of these States. 
Continued emphasis was given to preventing the spread of the 
Japanese beetle by aircra ft. Approximately L5, 100 aerosol treatments 
of planes were made at 52 airfields within the infested area. An addi- 
tional L,600 residual treatments were given military and commercial 
airplanes at 26 airfields. DDT was applied to vegetation on which 
the pests might feed or light at 1 1 commercial and military airfields. 
This work was done cooperatively by airfield and Bureau employees. 
Surveys at outlying fields where treated plane- landed revealed no 
new infestations resulting from spread by airplanes. The State <>{ 
Georgia cooperated in applying control treatments at a previously 
discovered infestation at the Atlanta, Ga., airport. 
Products certified during the fiscal year for movement to points 
outside the regulated area included more than L16 million plant-. 
I. !."><> carloads and truckloads of fresh fruits and vegetables, and 
2,000 tons of soil. These had an estimated value oi $16,500. 
and shippers treated according to Bureau-approved methods 
all products likelj to be in fested. 
S isonal certification requirements for the movement <d' fruits and 
tables were made effective dune L2, L951. Whereas certification 
formerly required for all fruits and vegetables moving by refrig- 
erator car or motortruck, the L951 requirements were limited to I 
coin on the cob, fresh beans in the pod, cabbage, apple-, and peaches.
