12 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1933 
All field work to determine the present scope of the beetle outside the 51,339 
square miles then under regulation was performed with traps. The 1932 field- 
inspection work was of greater scope than any previously attempted. Traps 
were in operation in all Atlantic Coastal States and in selected cities in States 
as far west as Michigan. In all, 45,721 traps were used in determining the 
presence or absence of beetles in nonregulated territory. In most communities 
examined, 400 traps were distributed at points of likely infestation. Traps on 
each route were periodically visited by a trap inspector. Experienced men 
with small trucks were assigned to supervise the work of a number of trap 
inspectors. Trapping was already in progress in Florida, Georgia, North Caro- 
lina, South Carolina, Virginia, Maryland, West Virginia, and Ohio at the begin- 
ning of the fiscal year. During July, trap distribution began in Pennsylvania, 
New York, Massachusetts, New Hampshire, and Michigan. Final placement 
of traps was made in Vermont and Maine during August. Throughout the 
summer traps were operated for periods varying from 30 to 60 daj^s in 3 cities 
each in Florida and Georgia, 4 cities in South Carolina, 5 cities in North Caro- 
lina, and 3 cities in West Virginia. In the unregulated portions of States already 
partiall}'' quarantined, traps were in operation in 32 towns and cities in Vir- 
ginia, 35 communities in Maryland, 50 localities in Pennsylvania, 43 localities 
in New York, and in 62 Massachusetts towns and cities. The New England 
trapping program was carried on in 6 cities each in Maine, New Hampshire, 
and Vermont. In the East North Central States traps were placed in 13 Ohio 
cities, in Detroit, Mich., and Richmond, Ind. Selection of these 273 towns 
and cities as sites for trapping activities was made on the basis of their ranking 
as transportation centers, as possible destination points of illegally transported 
infested produce or nursery stock, or as possible centers affording favorable 
environments for the establishment of a few beetles accidentally carried from 
the zone of heavy infestation. 
Most remote from the regulated zone of the first-record finds are the infesta- 
tions of a few beetles each discovered at Florence, S.C.; Winston-Salem, Raleigh, 
and Durham, N.C.; Roanoke and Lynchburg, Va.; Wheeling, W.Va.; Canton, 
Cleveland, Columbus, Steubenville, and Zanesville, Ohio; Detroit, Mich.; 
Buffalo, Niagara Falls, Rochester, and Syracuse, N.Y.; Bellows Falls, Brattleboro, 
Rutland, and White River Junction, Vt. ; Dover, Keene, Manchester, Portsmouth, 
and Weot Lebanon, N.H.; and Augusta, Kennebunk, and Portland, Maine. 
Beetles in considerable numbers were collected at the site of the newly discovered 
infestation in Concord, N.H. In the unregulated portion of Pennsylvania, 
infestations in 27 localities were determined. Beetles were collected in 17 cities 
and towns in nonregulated territory of Virginia, and in 31 communities outside 
the then-restricted zone in Massachusetts. 
An incipient infestation discovered at Charleston, S.C., in 1931 and surface 
treated the following fall with arsenate of lead failed to disclose any beetles in 
1932. Nominal increase only was noted at previously discovered infestations in 
Annapolis and Chevy Chase, Md.; Boston, Mass.; Buffalo and Little Falls, N.Y.; 
Cleveland and Columbus, Ohio; Laughlintown, Ligonier, New Castle, Pittsburgh, 
and Tyrone, Pa.; and Richmond, Va. 
Trapping activities for the summer of 1933 were fully organized in North 
Carolina, South Carolina, Virginia, and West Virginia by the end of the fiscal 
year. First placement of traps was made in Charleston, S.C., on May 27. The 
only first-record find recorded was a catch of two beetles at Emporia, Va. 
SUPPRESSIVE MEASURES 
Intensive eradication meajures were applied at Erie, Pa. In conjunction with 
the season's trapping activities, surface application of lead arsenate was made to 
soil and sod in infested sections. Throughout the summer, trap inspectors made 
six applications of poison spray containing attractants to foliage in the infested 
district of the city. Traps distributed in Erie during 1931 yielded 170 beetles. 
Catches of 282 beetles were made in 1932, an increase which is not considered 
significant. 
Application of lead arsenate to tne two small sections in Detroit, Mich., where 
a few beetles were trapped in August 1932 was completed in September. This 
suppressive work was a joint project with the authorities of the State of Michigan 
and the city of Detroit. Similar poison application was made at the site where 
two beetles were trapped at Florence, S.C. Lead arsenate for the latter work was 
supplied by the State of South Carolina. 
Community spraying for Japanese-beetle control, in cooperation with the 
Maryland State Horticultural Department, was carried on during June 1933 in
