and tor the rental of spray tracks ased to supplement those owned by the 
citj of Detroit At the height of the work as many as M Bprayers were In use 
and Ti; Laborers were employed. The work was completed oo June 3. f

distrl • 
in cooperation with officials of the South Carolina State Crop Pesl Commis- 
sion, three employees of the division, working from April 22 to May 5, applied 
B tons of lead arsenate to L6 acres in and surrounding the sections of Greenville, 
.» beetles were caught during 1085. An appropriation of $1,000 
from tii" State contingent fund was available for the purchase of material. 
Two high-pressure sprayers were driven to Greenville from the project's ware- 
house at New Cumberland, Pa. 
Following the quarantine hearing in November, the Ohio Department of 
culture and Conservation obtained an emergency appropriation 1 from 
the Ohio Board of Control for treatment of approximately 250 acres in Ohio 
cities and towns where Japanese beetle Infestations were found during 1935, 
The funds were made available too late to apply the lead arsenate effectively 
before freezing weather. Had the treating plans been carried out, the Insecticide 
would have been applied in the spring of L936. The Dumber of traps scattered 
throughout Ohio during L935 were not sufficient to delimit the Infested sections 
in the several communities where apparently established infestations were found 
to exist, in the absence of definite information on the limits of each area, it 
did not appear practicable to treat the known infested sections, because of the 
Likelihood thai intensive trapping during 1936 would considerably extend the 
zones requiring soil poisoning to suppress the larval population. Accordingly, 
the Ohio treatments were deferred pending the results of another season's 
trapping. 
Approval was received during March hy the Missouri Department of 
culture of a State Works Progress Administration project for combined lead 
arsenate treatment and intensive trapping Of the infested sections of St. Louis. 
A balance of an original allotment of $5,000 by the city of St. Louis was also 
available during the year. Lead arsenate application- were begun on Jtr 
FEDERAL AND STATE REGULATORY MEASURES 
Seventy-five QUrserymen, nursery association representatives, and State of- 
ficials from 23 States and the District of Columbia attended a public hearing 
neid in Washington, l>. C, on November 16, 1035, to consider the advisability 
of revoking the Japanese beetle quarantine or extending it to the Stab 
Illinois, Indiana. Michigan, Missouri. Ohio, North Carolina, and South Carolina. 
Testimony at the hearing was almost unanimously in favor of continuance of 
the quarantine. Recommendations were also made that the small isolated 
Infestations should not be included in the quarantined area but that every effort 
should be made to suppress these infestations. 
Conferences and exchanges of correspondence with officials in uonregulated 
States concerning the established infestations from which secondary spread 
might be expected resulted in the adoption of several different plans to prevent 
dispersal oi th" Insect 
Following assurances from officials of uonquarantined states containing iso- 
lated Infestations that adequate asures would be taken to prevent the spread 
of the beetle from infestations within their borders, revised regulations were 
I, effective March in, 1936, to extend the restricted zone to cover Important 
Infestations determined by traps set in Lewiston, Gorham, and Auburn. Maine: 
[thaca, N. v : ;i series of communities in 'Loudoun, Fauquier, and Culj 
Counties, and suburban areas contiguous t" Richmond, Va.; ami a scattering 
of Maryland Localities in Carroll, Howard. Caroline, Prime «, ges, and 
< lharies < lount les. 
Supplementary Intrastate quarantines i>sneii by the states of Maryland. New 
York, Virginia, and West Virginia placed under regulation the newly federally 
regulated area in each State, together with Isolated infestations at Hurlock 
and Frederick, Aid.; Buffalo, \. v.: Charlottesville, Roanoke, and Salem, Va.; 
and Chester, Clarksburg, Fairmont, ami Parkersburg, w. Va. 
factory treating programs in Detroit, Mich., Qreenville, B.C., Brie, Pa., 
Louis, Mo., and Indianapolis, Ind., adequately protected noninfested sec- 
tions from secondary dissemination of the pest from these detached points.
