PREBACE. 

The acreage devoted to sugar-cane culture in the southern United 
States has increased rapidly in recent years. Some of the cotton 
lands, abandoned because of the depredations of the cotton boll 
weevil, are being planted to cane. New lands are being planted to 
the crop in the Rio Grande valley and in the reclaimed areas in the 
lower Mississippi valley. It is stated that quite an area of land 
in process of reclamation in the State of Florida will be planted to 
sugar cane. It is desirable that the experience obtained through 
investigations of insects injurious to sugar cane in the Hawaiian 
Islands be placed at the disposal of the planters in our Southern 
States in order that the sugar industry in those States may receive 
practical benefit therefrom. 
The Hawaiian planters are well provided with expert advice and 
have at hand numerous reports dealing with the subject, which latter, 
unfortunately, are not available for general distribution. This report 
is written primarily, therefore, for the information of our mainland 
planters. 
Acknowledgment should be made of the courtesies extended*to 
the writer by the members of the entomological staff of the Hawaiian 
Sugar Planters’ Association Experiment Station during his return 
visit to the Hawaiian Islands in March and April, 1909.
