80 ANNUAL REPORTS OF DEPARTMENT OP AGRICULTURE, 1953 
treatments were applied to planes. Trap- and foliage i reatments were 
used to reduce beet le infestal ions at many infested airfields from which 
there was outgoing t raffic to noninfe-ted arm-. Approximately 2 mil- 
lion hectic- were collected m these trap-. Cooperating military and 
commercial airline employees removed Large but unrecorded numbers 
of beetles from clothing and hand baggage of passengers entering 
planes. 
Cooperal ive experiments to kill beetles in airplane- were continued. 
These showed that a commercially available low-pressure throw-away 
dispenser containing standard insecticide aerosol G-G51 or military 
stock aerosol is effect ive against the hectic. 
In cooperation with State pest-control agencies, soil and foliage 
treatments to control isolated beetle infestations were applied in 93 
localities in 11 States during 1952. In these treatment- 64,000 gallons 
of DDT foliage spray and L65 tons of soil insecticide-, mostly DDT, 
were used. Cooperating States and local interests furnished most oi 
the material and labor for these treatments. The Bureau's contribu- 
tions were principally technical assistance and special equipment. 
Cooperative control treatments were applied during dune L953 in 
East St. Louis, 111.: Covington, Russell, and Louisville, Ky.: Atlanta 
and Dahlonega, Ga. ; and in 16 Ohio localities. 
The use of soil insecticides applied in powder form with low-cost ap- 
plicators was recommended by the Bureau and accepted DV some State 
cooperatives with a consequent saving in Labor costs. This permitted 
more extensive and timely treatments. This method was used in 
Louisville, Ky., where t35 acres were surface treated with DDT. 
A new nursery treatment using a mixture of ethylene dibromide and 
chlordane was authorized on dune L5, L953, for use on hare-rooted 
plants. This provides for immediate certification of treated plants 
without a holding period subsequent tot reatment 
Spot checks during April and May L953 made at State highway- 
patrol weighing stations showed considerable nursery stock moving 
via motor truck westward from the regulated areas. While most of 
the Stock originated in Ohio and Pennsylvania, some of it came from 
nurseries in New Jersey, Connecticut, West Virginia, New York, and 
Rhode [sland. All truckers had proper quarant ine cert ificat ion. 
Seasonal-cert ificat ion requirements for fruits and vegetables moving 
via refrigerator car or vent ilated motor truck wen' instituted on dune 
L8, L953, 
Quarantine certification services involved the certification ^( L72 
million plant-. 30,000 packages of fruits and vegetables, and 1,000 
tone of -oil. These were cert ified for 1,930 commercial establishments 
and 680 individual shippers in the regulated area. Articles certified 
had an est [mated value of $13 million. 
sine.' many nursery establishments in eastern North Carolina are 
now affected by both the Japanese hectic and white fringed beetle 
quarantine, a joint certificate covering both quarant ines r as prepared 
and issued to eligible nurseries. A similar joint Japanese beetle and 
gypsy moth certificate has been in use for many years in the \ 
England Stato .
