Overwintering of the raisin moth in a vineyard.--Perez Simmons, 
of the Fresno, Calif., laboratory, reports: "Working in a vineyard 
of Zante granes (currants) where the infestation by Ephestia figu- 
dilella Greg. was exceptionally heavy, apparently because much waste 
fruit was on the ground, H. C. Donohoe obtained information about 
the locations in which larvae vf this insect pass the winter. By 
examination of soil samples with the trendle sifter, and of. the bark 
on grape trunks, the relative concentreticns of larvae in strips 
parallel to the rows of vines was cbtuined, as follows:

Inmature stages of Jap beetle in the soil.--In connection with 
the regular seasonal soil surveys conducted by H. Fox, Moorestown, 
N. J., it is of interest to nota that one egg and four first-instar 
larvae were found close together in a digging at the Tavistock Golf 
Course in Haddonfield, N. J., on January 26. The larvae have been 
definitely identified as Popillie japonica Newm., and, insofar as it 
is possible to determine by close examination, the egg appears to be 
of the same species. The egs was transferred to an incubator but 
failed to hatch, which is in accord with experiments conducted in 
1930, indicating that eggs exoosed for more than a month to tempera- 
(ae he) 
tures below 55° F. are killed.
