Iii Michigan, from September 18 to November 15, 63 acres were 
treated, approximately 50 acres in Detroit and the remainder in 
Dearborn. Birmingham, Grosse Pointe, and Melvindale. 
In St. Louis, Mo., applications were made to 27 acres to cover 
the premises on which 26 beetles were trapped in the summer of 
1939. Not one beetle was caught in treated areas where previously 
hundreds had been taken. 
At Dansville, N. Y., the local nurserymen's association, acting on 
the advice of State officials, initiated their own soil-treating program, 
contributing one-half and underwriting the other half of the $4,000 
required to treat an infestation that has not yet spread to any of the 
extensive nursery-growing sections in that vicinity. During the first 
2 weeks of November 19.3 acres in Dansville were treated in the area 
where 116 beetles were discovered during the 1939 trapping season. 
In North Carolina 302.5 acres in 17 cities and towns received ap- 
plications. Every known infestation in the State, excepting 1 at 
Asheville, was treated at a dosage of 1,000 pounds per acre. Treat- 
ment was begun September 25 and completed December 16. 
In Ohio 4 acres were treated at Belpre between June 29 and July 
6, 1939. At Ashtabula, Belpre, Conneaut, Gallipolis, and Marietta 
166.35 acres received applications during the spring of 1940. At 
Zanesville 12.6 acres were sprayed between May 10 and 21. 
At Berry ville, Va., where three beetles were trapped in the sum- 
mer of 1939, 4.34 acres received applications between December 11 
and 13. From March 11 to April '3, 1940, 29.5 acres in Winchester 
were treated. 
Throughout the year the treating work has been largely spon- 
sored by either the State or the municipalities affected. The Bu- 
reau *s contribution included furnishing spray equipment, drivers for 
the spray trucks, and supervisors to cooperate with the men in charge 
of the work for the sponsoring agency. Labor and materials were 
furnished by the cooperating agencies, which also made all local 
arrangements. 
FEDERAL AND STATE REGULATORY MEASURES 
At a public conference held in Washington, D. C, on February 
27, 1940, to consider the present status of the Japanese beetle quar- 
antine, there was a large attendance of nursery association repre- 
sentatives. State plant-pest officials, and others interested. This 
was the first public meeting to consider this quarantine since the 
hearing held on November 16, 1935. A majority of those present 
favored retention of the quarantine. 
This year there was no necessity to consider the advisability of 
placing any additional States under quarantine, With the exception 
of Asheville, N. C, all important infestations discovered in unquar- 
antmed States were treated with a dosage of lead arsenate >uflicient 
to eliminate all hazard of beetle spread from these communities. 
By an amendment to the Japanese beetle quarantine regulations, 
effective July 1, 1939, four townships in Cuyahoga County, Ohio, 
were added to the regulated area, bringing the entire county within 
the area. With the extension of the continuous regulated' area to 
include Cleveland, all restricted commodities moving from this point
