AN ANNOTATED BIBLIOGRAPHY OF THE MEXICAN 

 COTTON BOLL WEEVIL. 



{Anthonoinus grandis Boh.) 



By F. C. BisHOPP, Agent and Expert. 

 INTRODUCTION.! 



The invasion of the United States b}^ the cotton-boll weevil has 

 caused revolutionary changes in the area in which cotton is produced. 

 Not only have agricultural practices been changed, but the whole 

 economic structure of the States concerned has been affected. More- 

 over, through trade relations the boll-weevil problem has attracted 

 extensive attention outside of the United States. The literature 

 that has naturally grown up on this subject is of interest to various 

 persons. It interests entomologists on account of the detailed inves- 

 tigation of the insect and for other reasons; cotton planters, on 

 account of their own experience in producing the staple ; cotton mer- 

 chants, on account of the manner in which the size and distribution 

 of the crop has been affected; and historians and economists, on 

 account of the manner in which institutions, such as the relation 

 between tenant and landlord, liave been affected. 



The object of the present publication is to furnish an index to this 

 literature for the use of the persons who have been mentioned and 

 others. There is a present demand for such a publication, especially 

 in the Eastern States of the cotton belt, and this demand will 

 undoubtedly increase as time passes. 



The literature on the boll weevil is probably as extensive as that 

 on any other injurious insect. It is scattered through hundreds of 

 publications, covers about 3,500 pages, and is in several languages. 

 This paper includes all of the more im])ortant writings, comprising 

 297 titles. In order to include a considerable number which are of
