INSECTS AND OTHER ANIMAL Pests [NyuRIOUS TO Firtp Beans 1015 
present. This work in stored beans is the only loss occasioned by this 
insect in New York (Plate LX XI, 3). 
In an effort to determine the summer habits of the weevils that emerge 
from infested seed when it is planted, the writer, on June 18, 1918, placed 
weevils, and beans containing larvae and pupae 
of the insect, in a field cage in which small bean 
plants were growing. On July 2 it was noted 
that the parent beetles had eaten small pieces 
from the leaves of the plants; and on August 15 
the beans just below the surface of the ground, 
that had not germinated, were filled with larvae, 
pupae, and adults of the insect. This condi- 
tion still prevailed on October 1. 
Bean weevils are not a serious pest under 
New York conditions, because of the low tem- 
perature during the winter. Garman (1917) 
has shown by experiments that a temperature 
of 0° F. for twenty-four hours will destroy all 
stages of this pest. Thus the insects are prob- 
ably never able to live thru the cold winters pee eee as 
in the bean fields. At a temperature of 50° F., 
feeding and reproduction are so checked that little harm results. A erower 
in New York who saves his seed from his crop of the preceding year and 
keeps it in a barn or some other cold place, need have little fear of weevil 
injury. lke same is true where seed is kept in bean warehouses at low 
temperatures. In warm stores and seed- 
a a - houses, however, which often have a few 
weevils present in left-over stock, the 
continuous multiplication of the pests 
often results in almost total destruction 
of the beans.

THE BLUE-BANDED MILLEPEDE 
(Julus caeruleocinctus Wood) 
In July, 1917, a bean field near Ba- 
tavia, New York, showed a heavy infes- 
tation of the millepede, or thousand- 
HT OOM Tan BLUR -BANDED mur legged worm, Julus caeruleocinctus (Of 
PEDE, X 23 the order Diplopoda) (fig. 99). The soil 
in this field is sandy, and when observed 
by the writer it was dried out and crusted, altho only two weeks before it 
had been very wet. The millepedes were feeding on the plant parts below 
ground and had eaten the main roots to such an extent that some of the 
plants were almost severed from them (fig. 100,C). Nearly every plant
