ments such removal was begun two months later, in May--in other words, 
scheduled to meet the normal activity of the weevils in relation to 
available new cotton. A limited number of natural Shelters were also 
used in these experiments, excluding a number of types of shelters and 
material which had little or no relation to any normal hibernating con— 
aevions. - C, L, M. 
Cooperative boll weevil cage hibernation tests.—-R. C. Gaines, Tal- 
lulah, presents "a summary of boll weevil emergence in hibernation cages 
at the various State and Federal stations. * * * At stations where the 
records are available on emergence in cages prior to June l, comparisons 
with previous years' records are interesting. At Poplarville, Miss., 
0.53 per cent of the weevils had emerged prior to June 1 in 1932, as 
compared with O per cent in 1929, 0.10 per cent in 1928, 0.20 per cent 
in 1927, and 0.10 per cent in 1926. At Auburn, Alabama, 5.47 per cent 
of the weevils had emerged prior to June 1 in 1932, as compared with 
0.20 per cent in 1929, 0.07 per cent in 1928, 0.24 per cent in 1927, 
0.60 per cent in 1926, and 14.80 per cent in 1925. * * * At Tallulah 
10.27 per cent of the weevils had emerged prior to June 1, by far the 
highest figure ever recorded at this station, the average for the years 
of 1916 to 1931, inclusive, being less than 1.00 per cent." 
Boll weevil hibernation at College Station, Tex.--E. W. Dunnam and 
R. W. Moreland report that "The number of weevils emerging from the hi- 
bernation cages this month was somewhat less than that of last month, 
* * * The three series of weevils installed in moss are yet yielding 
more weevils than the three series installed in ccrnstalks. It is in- 
teresting to note that in the two woods series this is the first month 
that more weevils were taken from the moss than from the leaves. We 
have observed right along that proportionately more weevils emerge from 
the November 1 moss cages in the woods than from the November 1 moss 
cages located in the field." 
Chemotropism of boll weevil.--— G. L. Smith and assistants submit 
from Tallulah, La., "a summary of the results of the chemotropic 
studies of the boll weevil during February, March, and April, when green 
cotton plants were absent from the fields. The greatest gain (recorded) 
for trymethylamine over the untreated flight screens was 31.6 per cent, 
with 4 per cent solution of trimethylamine. The greatest gain for am- 
monium hydroxide over the untreated screens was 20.3 per cent, with a 
1-1/3 per cent solution, Comparing trimethylamine with ammonium hydroxide, 
the 4 per cent solution of trimethylamine showed a gain of 15.6 per cent 
over 4 per cent solution of ammonium hydroxide, but trimethylamine showed 
a loss of 13.9 per cent when compared with 1 per cent solution of am-— 
monium hydroxide."

Sand-fly larvae killed by creosoted pine sap.—-W. E. Dove, Charles— 
ton, S. C., reports that "Spray tests made with creosoted pine sap dur-— 
ing the spring gave a kill of sand fly larvae ranging from 1A tO 
per cent. The spray treatments were not made on the open marshes.
