in Chester, Huntington, Moundsville, and Parkersburg. Recurring infestations 
at Clarksburg, Fairmont, Martinsburg, and ^'heeling increased in number of 
beetles trapped, and the new infestations determined at Chester and Parkers- 
burg involved finds of a fair number of insects. There was a general increase 
in the number of traps used in West Virginia. 
Trapping in Virginia in 1935 extended to 37 towns and cities, with resulting 
catches in 24 localities. These included first-record catches at 11 points, the 
most important of which were in suburban sections of Richmond. 
Traps set in 39 North Carolina communities revealed infestations in 16 cities. 
The largest infestation in the State was disclosed at Winston-Salem, where a 
few beetles had been collected in both 1932 and 1933. 
With the single exception of a one-beetle find at Emmitsburg, the Maryland 
infestations were found where beetles had been discovered in previous years. 
A number of the localities were first found infested as long ago as 1932. 
There was a further progressive decrease in the number of beetles that could 
be collected in Erie, Pa. • Since 1932, when 2S2 beetles were caught, trapping 
in successive years has netted 1G7, 114, and, in 1935, 73 beetles. 
Trapping in New York was carried on in 14 cities, with beetle captures 
recorded in 6 localities where infestations had been determined in previous 
years. 
In the nonregulated section of Maine, increases were noted in the infestations 
at Auburn, Gorham, and Lewiston. 
Early-season trapping activities in 1936 began with the placement of traps 
in St. Louis, Mo., on May 4. Southern trapping began in South Carolina witli 
the distribution of traps in 11 cities throughout the State between May 26 and 
June 11. Trap setting was completed in Athens, Augusta, and Savannah. Ga., 
between May 29 and June 10. 
By the end of the year additional traps were in operation in 4 cities and 
towns in Illinois, 6 cities in Indiana, 4 localities in Kentucky, 57 nonregulated 
communities in Maryland, 3 other cities in Missouri, 27 North Carolina towns 
and cities, 10 Ohio communities. 4 Tennessee cities, 65 cities and towns in 
Virginia, and at 3 points in West Virginia. For the purpose of checking an 
apparently erroneous report of the finding of a single Japanese beetle on the 
farm of the Kansas State College at Manhattan, Kans., traps were operated 
during June at that point with negative results. The earliest beetle catch in 
the season of 1936 was made at Charleston, S. C, on May 30. 
Trap captures recorded during May and June included a single beetle in 
Savannah, Ga. ; 23 beetles in St. Louis, Mo. ; 2 beetles in Bristol, Tenn. : small 
captures at 10 points in North Carolina ; 15 and 11 beetles, respectively, in 
Greenville and Charleston, S. C. ; 2 beetles in Bon Air, Va. : and 1 beetle at 
Marietta, Ohio. Finds at Savannah, Ga., Wilson, N. C, and Bristol. Tenn.. 
were first records ; the others were survivals of previously determined infes- 
tations. 
SUPPRESSIVE MEASURES 
Application of lead arsenate to two new Japanese beetle infestations in St. 
Louis, Mo., began on August 8, 1935. and was completed on October 8. From 
September 27 until completion of the work the spraying was performel with 
State-supplied labor. Approximately 100 acres were sprayed at the rate of 1,000 
pounds of lead arsenate per acre. 
Similar applications of lead arsenate were made between October 9 and 24 
to the soil in newly discovered infested sections of Indianapolis, Ind.. outside o^ 
the section treated in 1934. Two federally owned sprayers were shipped to 
Indianapolis from the central Pennsylvania warehouse, and the two sprayers that 
had been in St. Louis were driven to Indinnapolis. In addition to an extension 
of the area treated in 1934, two isolated sections were sprayed. Approximately 
20 tons of State-purchased lead arsenate were applied at the rate of 1,000 
pounds per acre. Labor for the Indianapolis project was paid from relief funds 
Several light snowfalls interrupted soil treatments applied in Erie, Pa., from 
April 13 to 24. 1936. Two federally owned tank sprayers were provided to apply 
the State-purchased lead arsenate. Hosemen and other laborers were also pro- 
vided by the Pennsylvania Department of Agriculture. Four tons o\' lead arse- 
nate were sprayed on 8 acres of ground in sections of Erie outside of previously 
poisoned areas where Japanese beetles were trapped in 1935. 
Treating operations began in Detroit, Midi, on April 30. A Works Progress 
Administration conservation project in Detroit provided funds for the pur
