absence of rain. * * * The mixture has now been applied to 200 acres of 
shade-grown tobacco under a great variety of conditions. An entirely 
satisfactory kill has been obtained and no burn has been observed or re— 
ported." The value of this new control method had been estimated as 
follows: "Saving by elimination of burned leaves and by additional flea— 
beetle control, 7 per cent. Shade-grown tobacco in this immediate sec— 
tion, 2,700 acres; yearly average value, $2,000,000; yearly saving, 
$149,000." 
"During. this month (July)," writes J. U. Gilmore, of the Clarxs— 
ville, Tenn., field laboratory, "chemotropic control of the green June 
beetle adult was attempted in asmall area near Guthrie, Ky., where the 
larvae of this beetle have done considerable damage in former years. As 
a result of previous observation upon this type of control, a series of 
30 flat pans were placed upon stakes about 4 feet long. These pans were 
of 2-quart size, and 11/2 quarts of the following mixture was placed in 
each pan: Brown sugar, 2 pounds per gallon of water. During the first 
week of the experiment, only water was added to the pans to increase the 
quantity of the fluid so that the June beetles could be drowned in it, 
which was the method of retaining the catch. Later, new batches of brown 
sugar mixture were added from time to time. In the last few days of the 
experiment, honeybees seriously interfered by carrying away the mixture.” 
The total number of Cotinis nitida cavght during July was 9,820. 
Harvest of the 1931 field experiments for the control of the 
seed-corn maggot as a pest of newly planted seed potatoes was completed 
the first week in July. The work was conducted by W. J. Reid, jr., in co- 
operation with the U. S. Bureau of Plant Industry, and was located at 
Charleston, S. C., Chadbourn, N. C., and New Bern, N. C. Mr. Reid says: 
"The field control experiments of the 1931 season were confined almost 
entirely to tests of the value of seed suberization, or corking, in ad- 
vance of planting as a means of preventing seed-—corn maggot injury to 
seed potatoes. This process gave very promising results as a control 
measure in experiments of three previous seasons. The results of the 
1931 tests were also very encouraging. In each of the l2 different field 
control experiments potato seed suberization in advance of planting gave 
excellent, 98.86 per cent, control of the seed—corn maggot." 
On the control of the European earwig, S. E. Crumb, Puyallup, 
Wash., reports: "Recently we have had an opportunity to determine the 
feasibility of controlling earwigs after they have taken up their abode 
in beehives. It is known that earwigs are fond of honey, and it was 
feared that they might remain permanently in the hives, where control 
might be quite difficult. Strange to say, the bees do not seem to resent 
the presence of earwigs, since the earwigs are often found in situations 
such that the bees could readily attack them. Dissections of stomachs of 
earwigs from beehives gave evidence that they had fed freely upon the 
honey, but in every case the stomachs contained a considerable amount of 
vegetable matter, indicating that the earwigs found it necessary to leave 
the hive to obtain a portion of their food. Acting upon this indication 
earwig bait was scattered about the hives with excellent results."
