burned. The soil was sprinkled with petroleum, carefully plowed, harrowed, 

 rolled, oiled, reharrowed, rerolled, and rerolled. The land was then flooded for 

 5 consecutive days.

 An account is given of the habits, life history, and depredations of this pest, 

 based in part upon publications of the U. S. D. A. Experiments were conducted by 

 the Mexican Commission of Agricultural Parasitology for the purpose of deter- 

 mining successful means of combating the pest. It is recommended that attention 

 be given the proper rotation of crops, careful selection of seed, flooding of the 

 lands, and destruction of cotton plants in the fall. 



1904 - Hunter, W. D. Information concerning the Mexican cotton-boll weevil. U.S. D. A. 

 Farmers' B. 189:31, 8 fig. 



As a result of the investigations thus far made in combating this insect, it is 

 concluded that there is not even a remote probability that the boll weevil will ever 

 be exterminated. The belief is expressed, however, that the insect can be suffi- 

 ciently controlled to allow the production of profitable crops by practicing a num- 

 ber of preventive measures, such as early planting, use of seed of early varieties, 

 thorough cultivation of the fields, planting rows far apart, destroying all the cotton 

 stalks in the fields when the weevils become so numerous that all fruit is being 

 punctured, and more extensive use of fertilizer. 



1904 - Hunter, W, D, The most important step in the cultural system of controlling the 

 boll weevil. U. S. D. A., Bur. Ent. C. 56:7. 



Promotion of early crops of cotton for the prevention of boll weevil injury 

 has been actively carried on by the Department. The matter of obtaining an early 

 crop, however, is considered secondary in importance to the destruction of cotton 

 plants in the field during the fall. 



The author mentions that fall destruction of cotton plants prevents the de- 

 velopment of many weevils which would otherwise become adult within a few 

 weeks of the time of hibernation and also destroys a great majority of the weevils 

 which have already become adult. The only weevils which survive the winter are 

 those which become adult late in the season. The clearing of the cotton field in 

 the fall permits the practice of fall plowing.

25:157-170, 6 fig. 



Contains a review of the work done on this insect, a statement of the methods 

 of control recommended, and the changes made in these recommendations as the 

 investigations proceeded. Attention is called to the fact that spraying has been 

 generally abandoned as a remedy and that hand picking is meeting with little favor.

gations. U. S. D. A., Farmers' B. 216:32, 5 fig. 



This bulletin was prepared to replace Farmer's B. 189. It contains a restate- 

 ment of the previous recommendations of the Bur. of Ent. regarding the means of 

 controlling the boll weevil, together with an account of more recent work which 

 has substantiated those recommendations. 



1906 - Newell, W. The remedy for the boll weevil. La. Crop Pest Comn. C. 3:20, 5 fig. 



Maps show the gradual advance of the boll weevil into La. with reference to 

 the effects of cold rainy winters upon the pest. It is believed, however, that the 

 boll weevil will be able to winter successfully in the cotton regions of La. Cul- 

 tural methods are considered the only efficient remedy for controlling the boll 

 weevil. These consist of early planting, the use of varieties which mature quickly, 

 the application of fertilizers, thorough cultivation, and destruction of cotton plants 

 in the fall, as well as other material in which the beetles may hibernate.
