George W. Ellington, Sligo, reports that "Further tests, with para- 
dichlorobenzene at different temperatures, were conducted during the 
month against certain species of insects attacking stored seeds. Ata 
temperature of 80° F. (rice weevil) Sitophilus oryzae L. adults. were 
killed in 8 hours, whereas 17 hours is required to kill this insect at 
a temperature of 60° F. The same fumigant at the above temperatures 
. gave similar results against other stored seed insects." 
S. E. McClendon, Thomasville, Ga., reports that "insects in stored 
grains have been active all winter, there being no cold weather to check 
them. Last November 100 ears of corn were collected in Glynn County, 
each ear was wrapped separately in paper, and the weevils counted in 
January with the following results: Eighteen ears were free of rice wee- 
vils; &2 ears had 3,608 rice weevils, or an average of 44 to the ear; 
66 ears had broad—nosed grain weevils." The numbers of rice weevils to 
the ear ranged from 5 to 112. Under conditions as favorable as those 
of the past winter considerable rice weevil activity in corn on Southern 
farms might be expected. 
E, M. Livingstone, of the cured tobacco insect investigations, 
Richmond, Va., has under observation about 600 larvae of the tobacco 
moth (Ephesti ne elutella Hbn.), according to W. D. Reed, who says: "The 
Climate has been so mild that these larvae had not gone into hibernation 
on January Sl. They have fed on the tobacco some during warm days, and 
remained sluggish in their feeding tunnels during cool weather. The last 
emengence in the laboratory took place on November 23. * * * Due to the 
unusually warm weather throughout January some activity of this insect 
continued throughout the month. The superintendent of the infested 
warehouses in Richmond reported that they observed living moths occasion-— 
ally until January 31. A. W. Morrill, jr., and I collected a living moth 
from one of the warehouses on January 6. On January 26 we examined eight 
hogsheads (8,000 pounds) of flue-cured tobacco from one of the infested 
warehouses. A number of living larvae were collected, all in active con- 
dition. They averaged 8.1 mm, in length, being about two-thirds grown.” 
Mr. Reed states also that "On January 15 we received a sample of 
flue—cured tobacco from a firm in Greenville, N. ©. In a l-pound sam- 
ple of this tobacco Mr. Morrill found 100 grown larvae and 35 adults 
of’ the tobacco beetle (Lasioderma serricorne Fab.). All of these in- 
sects were active and *pparently had not been in hibernation. This 
sample was collected from the surface of a hogshead in Greenville on Janu- 
ary 14. Examinations of hogsheads of flue-cured tobacco in the Richmond 
district during January did not reveal any active infestation." 
The work of examining bean samples from warehouses at Modesto, 
Calif., "has been finished for the season," writes C. K. Fisher. A table 
whick gives "the infestation of all the samples of all varieties of the 
19351 crop" is sybmitted by Mr. Fisher, who says: "Frem the table it will 
be seen that the total number of samples examined was 3,532 and that 2,286
