Description of the life history and habits of the boll weevil. Weevils at 

 work in squares can be recognized readily by what is called "flaring," an opening 

 out and spreading down from the bloom of the involucre or shuck, exposing them.

Ann. Sess. and the 6th of the La. Stock Breeders' Assoc., p. 64-71. 



General account of the insect, including life history and habits. The neces- 

 sity for maintenance of quarantines against cottonseed products and other farm 

 products likely to carry boll weevils is emphasized in connection with remaks 

 on the protection of Louisiana from invasion.

 17. 



First, it was suspected that this insect might have some native food plants 

 other than cotton. It was impossible, however, to find the weevil upon any plants 

 except cotton. It was feeding upon "loose cotton," and upon "kidney cotton." The 

 weevil is not especially common upon or injurious to either one of these species, 

 but the evidence obtained indicates that the "kidney cotton" is the original food 

 plant of the cotton boll weevil, and the author believes that this insect has no other 

 food plant than species of cotton. No parasites of the cotton boll weevil were 

 found in Cuba.

 Mex. ano 11, p. 503-504 and p. 515-516. Aug. 30.

 the distribution of the weevil in Mexico is given. Various remedies suggested by 

 investigators are presented. 



1904 - Wilcox, E. M. The Mexican cotton boll weevil. Ala. Expt. Sta. B. 129:91-104. 



A review of the introduction, history, and present distribution of the cotton 

 boll weevil within the United States. Notes are given on the habits and life history 

 of this pest. While a number of natural enemies have been mentioned as likely to 

 assist in the control of this pest, the author believes that improved methods of 

 cultivation are the only effective means of controlling the boll weevil so as to 

 raise profitable crops.

 and destructiveness of the pest, artificial remedies, the relation of birds to the 

 boll weevil, and insects frequently mistaken for this pest.
