SUGAR BEET. 



(See Beet.) 



SUGAR CANE. 



(Saccharum offidnarum Linnaeus. Family Gramineae.) 



Sugar cane is an important product of the Southern States, Hawaii, Porto Rico, and 

 the Philippines. It is grown in many parts of the world. Owing, however, to the 

 great danger of transporting insect enemies in the seed cane, its importation into 

 the United States, except through the Department of Agriculture, has been forbidden. 

 There is still a great possibility of the spread of its enemies from outside into the 

 islands. Some very important cane insects also attack corn. The sugar cane is host 

 to a multitude of insects which feed on its foliage, suck its juices, or bore in its stems or 

 roots. Many of these insects are not very likely to be imported, but in view of such a 

 possibility are briefly mentioned.
