HE SUGAR-BEET industry of the Rocky Moun- 
tain States is menaced by the presence of the 
beet leaf-beetle. Both the larva and beetle stages 
injure the foliage, especially of young sugar beets, 
and also attack table beets of all kinds and spinach. 
The beetles may be trapped by placing heaps of 
weeds or bundles of hay or straw where the beetles 
will seek them for winter quarters. Here they may 
be destroyed by burning between the middle of 
November and March. .
